  Base class for all sketches that use processing.core.

  Note that you should not use AWT or Swing components inside a Processing applet. The surface is made to automatically update itself, and will cause problems with redraw of components drawn above it. If you'd like to integrate other Java components, see below.

  The Window Size and Full Screen page on the Wiki has useful information about sizing, multiple displays, full screen, etc.

  As of release 0145, Processing uses active mode rendering in all cases. All animation tasks happen on the "Processing Animation Thread". The setup() and draw() methods are handled by that thread, and events (like mouse movement and key presses, which are fired by the event dispatch thread or EDT) are queued to be (safely) handled at the end of draw(). For code that needs to run on the EDT, use SwingUtilities.invokeLater(). When doing so, be careful to synchronize between that code (since invokeLater() will make your code run from the EDT) and the Processing animation thread. Use of a callback function or the registerXxx() methods in PApplet can help ensure that your code doesn't do something naughty.

  As of Processing 2.0, we have discontinued support for versions of Java prior to 1.6. We don't have enough people to support it, and for a project of our (tiny) size, we should be focusing on the future, rather than working around legacy Java code.

  This class extends Applet instead of JApplet because 1) historically, we supported Java 1.1, which does not include Swing (without an additional, sizable, download), and 2) Swing is a bloated piece of crap. A Processing applet is a heavyweight AWT component, and can be used the same as any other AWT component, with or without Swing.

  Similarly, Processing runs in a Frame and not a JFrame. However, there's nothing to prevent you from embedding a PApplet into a JFrame, it's just that the base version uses a regular AWT frame because there's simply no need for Swing in that context. If people want to use Swing, they can embed themselves as they wish.

  It is possible to use PApplet, along with core.jar in other projects. This also allows you to embed a Processing drawing area into another Java application. This means you can use standard GUI controls with a Processing sketch. Because AWT and Swing GUI components cannot be used on top of a PApplet, you can instead embed the PApplet inside another GUI the way you would any other Component.

  Because the default animation thread will run at 60 frames per second, an embedded PApplet can make the parent application sluggish. You can use frameRate() to make it update less often, or you can use noLoop() and loop() to disable and then re-enable looping. If you want to only update the sketch intermittently, use noLoop() inside setup(), and redraw() whenever the screen needs to be updated once (or loop() to re-enable the animation thread). The following example embeds a sketch and also uses the noLoop() and redraw() methods. You need not use noLoop() and redraw() when embedding if you want your application to animate continuously.

       public class ExampleFrame extends Frame {

           public ExampleFrame() {
               super("Embedded PApplet");

               setLayout(new BorderLayout());
               PApplet embed = new Embedded();
               add(embed, BorderLayout.CENTER);

               // important to call this whenever embedding a PApplet.
               // It ensures that the animation thread is started and
               // that other internal variables are properly set.
               embed.init();
           }
       }

       public class Embedded extends PApplet {

           public void setup() {
               // original setup code here ...
               size(400, 400);

               // prevent thread from starving everything else
               noLoop();
           }

           public void draw() {
               // drawing code goes here
           }

           public void mousePressed() {
               // do something based on mouse movement

               // update the screen (run draw once)
               redraw();
           }
       }

- - ### Field Detail

    - #### javaVersionName

          public static final String javaVersionName

      Full name of the Java version (i.e. 1.5.0_11). Prior to 0125, this was only the first three digits.

    - #### javaVersion

          public static final float javaVersion

      Version of Java that's in use, whether 1.1 or 1.3 or whatever, stored as a float.

      Note that because this is stored as a float, the values may not be exactly 1.3 or 1.4. Instead, make sure you're comparing against 1.3f or 1.4f, which will have the same amount of error (i.e. 1.40000001). This could just be a double, but since Processing only uses floats, it's safer for this to be a float because there's no good way to specify a double with the preproc.

    - #### platform

          public static int platform

      Current platform in use, one of the PConstants WINDOWS, MACOSX, MACOS9, LINUX or OTHER.

    - #### useQuartz

          public static boolean useQuartz

      Setting for whether to use the Quartz renderer on OS X. The Quartz renderer is on its way out for OS X, but Processing uses it by default because it's much faster than the Sun renderer. In some cases, however, the Quartz renderer is preferred. For instance, fonts are less thick when using the Sun renderer, so to improve how fonts look, change this setting before you call PApplet.main().

           static public void main(String[] args) {
             PApplet.useQuartz = false;
             PApplet.main(new String[] { "YourSketch" });
           }

      This setting must be called before any AWT work happens, so that's why it's such a terrible hack in how it's employed here. Calling setProperty() inside setup() is a joke, since it's long since the AWT has been invoked.

      On OS X with a retina display, this option is ignored, because Apple's Java implementation takes over and forces the Quartz renderer.

    - #### useNativeSelect

          public static boolean useNativeSelect

      Whether to use native (AWT) dialogs for selectInput and selectOutput. The native dialogs on Linux tend to be pretty awful. With selectFolder() this is ignored, because there is no native folder selector, except on Mac OS X. On OS X, the native folder selector will be used unless useNativeSelect is set to false.

    - #### g

          public PGraphics g

      The PGraphics renderer associated with this PApplet

    - #### frame

          public Frame frame

      The frame containing this applet (if any)

    - #### displayWidth

          public int displayWidth

      ( begin auto-generated from screenWidth.xml ) System variable which stores the width of the computer screen. For example, if the current screen resolution is 1024x768, displayWidth is 1024 and displayHeight is 768. These dimensions are useful when exporting full-screen applications.
      To ensure that the sketch takes over the entire screen, use "Present" instead of "Run". Otherwise the window will still have a frame border around it and not be placed in the upper corner of the screen. On Mac OS X, the menu bar will remain present unless "Present" mode is used. ( end auto-generated )

    - #### displayHeight

          public int displayHeight

      ( begin auto-generated from screenHeight.xml ) System variable that stores the height of the computer screen. For example, if the current screen resolution is 1024x768, screenWidth is 1024 and screenHeight is 768. These dimensions are useful when exporting full-screen applications.
      To ensure that the sketch takes over the entire screen, use "Present" instead of "Run". Otherwise the window will still have a frame border around it and not be placed in the upper corner of the screen. On Mac OS X, the menu bar will remain present unless "Present" mode is used. ( end auto-generated )

    - #### recorder

          public PGraphics recorder

      A leech graphics object that is echoing all events.

    - #### args

          public String[] args

      Command line options passed in from main().

      This does not include the arguments passed in to PApplet itself.

    - #### sketchPath

          public String sketchPath

      Path to sketch folder

    - #### DEFAULT_WIDTH

          public static final int DEFAULT_WIDTH

      Default width and height for applet when not specified
      See Also:
        Constant Field Values

    - #### DEFAULT_HEIGHT

          public static final int DEFAULT_HEIGHT

      See Also:
        Constant Field Values

    - #### MIN_WINDOW_WIDTH

          public static final int MIN_WINDOW_WIDTH

      Minimum dimensions for the window holding an applet. This varies between platforms, Mac OS X 10.3 (confirmed with 10.7 and Java 6) can do any height but requires at least 128 pixels width. Windows XP has another set of limitations. And for all I know, Linux probably lets you make windows with negative sizes.
      See Also:
        Constant Field Values

    - #### MIN_WINDOW_HEIGHT

          public static final int MIN_WINDOW_HEIGHT

      See Also:
        Constant Field Values

    - #### defaultSize

          public boolean defaultSize

      true if no size() command has been executed. This is used to wait until a size has been set before placing in the window and showing it.

    - #### pixels

          public int[] pixels

      ( begin auto-generated from pixels.xml ) Array containing the values for all the pixels in the display window. These values are of the color datatype. This array is the size of the display window. For example, if the image is 100x100 pixels, there will be 10000 values and if the window is 200x300 pixels, there will be 60000 values. The index value defines the position of a value within the array. For example, the statement color b = pixels[230] will set the variable b to be equal to the value at that location in the array.
      Before accessing this array, the data must loaded with the loadPixels() function. After the array data has been modified, the updatePixels() function must be run to update the changes. Without loadPixels(), running the code may (or will in future releases) result in a NullPointerException. ( end auto-generated )
      See Also:
        `loadPixels()`, `updatePixels()`, `get(int, int, int, int)`, `set(int, int, int)`, `PImage`

    - #### width

          public int width

      ( begin auto-generated from width.xml ) System variable which stores the width of the display window. This value is set by the first parameter of the size() function. For example, the function call size(320, 240) sets the width variable to the value 320. The value of width is zero until size() is called. ( end auto-generated )

    - #### height

          public int height

      ( begin auto-generated from height.xml ) System variable which stores the height of the display window. This value is set by the second parameter of the size() function. For example, the function call size(320, 240) sets the height variable to the value 240. The value of height is zero until size() is called. ( end auto-generated )

    - #### mouseX

          public int mouseX

      ( begin auto-generated from mouseX.xml ) The system variable mouseX always contains the current horizontal coordinate of the mouse. ( end auto-generated )
      See Also:
        `mouseY`, `mousePressed`, `mousePressed()`, `mouseReleased()`, `mouseMoved()`, `mouseDragged()`

    - #### mouseY

          public int mouseY

      ( begin auto-generated from mouseY.xml ) The system variable mouseY always contains the current vertical coordinate of the mouse. ( end auto-generated )
      See Also:
        `mouseX`, `mousePressed`, `mousePressed()`, `mouseReleased()`, `mouseMoved()`, `mouseDragged()`

    - #### pmouseX

          public int pmouseX

      ( begin auto-generated from pmouseX.xml ) The system variable pmouseX always contains the horizontal position of the mouse in the frame previous to the current frame.
      You may find that pmouseX and pmouseY have different values inside draw() and inside events like mousePressed() and mouseMoved(). This is because they're used for different roles, so don't mix them. Inside draw(), pmouseX and pmouseY update only once per frame (once per trip through your draw()). But, inside mouse events, they update each time the event is called. If they weren't separated, then the mouse would be read only once per frame, making response choppy. If the mouse variables were always updated multiple times per frame, using line(pmouseX, pmouseY, mouseX, mouseY) inside draw() would have lots of gaps, because pmouseX may have changed several times in between the calls to line(). Use pmouseX and pmouseY inside draw() if you want values relative to the previous frame. Use pmouseX and pmouseY inside the mouse functions if you want continuous response. ( end auto-generated )
      See Also:
        `pmouseY`, `mouseX`, `mouseY`

    - #### pmouseY

          public int pmouseY

      ( begin auto-generated from pmouseY.xml ) The system variable pmouseY always contains the vertical position of the mouse in the frame previous to the current frame. More detailed information about how pmouseY is updated inside of draw() and mouse events is explained in the reference for pmouseX. ( end auto-generated )
      See Also:
        `pmouseX`, `mouseX`, `mouseY`

    - #### firstMouse

          @Deprecated
          public boolean firstMouse

      Deprecated. Please refrain from using this variable, it will be removed from future releases of Processing because it cannot be used consistently across platforms and input methods.
      Used to set pmouseX/Y to mouseX/Y the first time mouseX/Y are used, otherwise pmouseX/Y are always zero, causing a nasty jump.

      Just using (frameCount == 0) won't work since mouseXxxxx() may not be called until a couple frames into things.

    - #### mouseButton

          public int mouseButton

      ( begin auto-generated from mouseButton.xml ) Processing automatically tracks if the mouse button is pressed and which button is pressed. The value of the system variable mouseButton is either LEFT, RIGHT, or CENTER depending on which button is pressed. ( end auto-generated )

      ### Advanced:

      If running on Mac OS, a ctrl-click will be interpreted as the right-hand mouse button (unlike Java, which reports it as the left mouse).
      See Also:
        `mouseX`, `mouseY`, `mousePressed()`, `mouseReleased()`, `mouseMoved()`, `mouseDragged()`

    - #### mousePressed

          public boolean mousePressed

      ( begin auto-generated from mousePressed_var.xml ) Variable storing if a mouse button is pressed. The value of the system variable mousePressed is true if a mouse button is pressed and false if a button is not pressed. ( end auto-generated )
      See Also:
        `mouseX`, `mouseY`, `mouseReleased()`, `mouseMoved()`, `mouseDragged()`

    - #### mouseEvent

          @Deprecated
          public MouseEvent mouseEvent

      Deprecated. Use a mouse event handler that passes an event instead.

    - #### key

          public char key

      ( begin auto-generated from key.xml ) The system variable key always contains the value of the most recent key on the keyboard that was used (either pressed or released).
      For non-ASCII keys, use the keyCode variable. The keys included in the ASCII specification (BACKSPACE, TAB, ENTER, RETURN, ESC, and DELETE) do not require checking to see if they key is coded, and you should simply use the key variable instead of keyCode If you're making cross-platform projects, note that the ENTER key is commonly used on PCs and Unix and the RETURN key is used instead on Macintosh. Check for both ENTER and RETURN to make sure your program will work for all platforms. ( end auto-generated )

      ### Advanced

      Last key pressed.

      If it's a coded key, i.e. UP/DOWN/CTRL/SHIFT/ALT, this will be set to CODED (0xffff or 65535).

      See Also:
        `keyCode`, `keyPressed`, `keyPressed()`, `keyReleased()`

    - #### keyCode

          public int keyCode

      ( begin auto-generated from keyCode.xml ) The variable keyCode is used to detect special keys such as the UP, DOWN, LEFT, RIGHT arrow keys and ALT, CONTROL, SHIFT. When checking for these keys, it's first necessary to check and see if the key is coded. This is done with the conditional "if (key == CODED)" as shown in the example.
      The keys included in the ASCII specification (BACKSPACE, TAB, ENTER, RETURN, ESC, and DELETE) do not require checking to see if they key is coded, and you should simply use the key variable instead of keyCode If you're making cross-platform projects, note that the ENTER key is commonly used on PCs and Unix and the RETURN key is used instead on Macintosh. Check for both ENTER and RETURN to make sure your program will work for all platforms.
      For users familiar with Java, the values for UP and DOWN are simply shorter versions of Java's KeyEvent.VK_UP and KeyEvent.VK_DOWN. Other keyCode values can be found in the Java KeyEvent reference. ( end auto-generated )

      ### Advanced

      When "key" is set to CODED, this will contain a Java key code.

      For the arrow keys, keyCode will be one of UP, DOWN, LEFT and RIGHT. Also available are ALT, CONTROL and SHIFT. A full set of constants can be obtained from java.awt.event.KeyEvent, from the VK_XXXX variables.

      See Also:
        `key`, `keyPressed`, `keyPressed()`, `keyReleased()`

    - #### keyPressed

          public boolean keyPressed

      ( begin auto-generated from keyPressed_var.xml ) The boolean system variable keyPressed is true if any key is pressed and false if no keys are pressed. ( end auto-generated )
      See Also:
        `key`, `keyCode`, `keyPressed()`, `keyReleased()`

    - #### keyEvent

          @Deprecated
          public KeyEvent keyEvent

      Deprecated. Use a key event handler that passes an event instead.
      The last KeyEvent object passed into a mouse function.

    - #### focused

          public boolean focused

      ( begin auto-generated from focused.xml ) Confirms if a Processing program is "focused", meaning that it is active and will accept input from mouse or keyboard. This variable is "true" if it is focused and "false" if not. This variable is often used when you want to warn people they need to click on or roll over an applet before it will work. ( end auto-generated )

    - #### online

          @Deprecated
          public boolean online

      Deprecated.
      Confirms if a Processing program is running inside a web browser. This variable is "true" if the program is online and "false" if not.

    - #### frameRate

          public float frameRate

      ( begin auto-generated from frameRate_var.xml ) The system variable frameRate contains the approximate frame rate of the software as it executes. The initial value is 10 fps and is updated with each frame. The value is averaged (integrated) over several frames. As such, this value won't be valid until after 5-10 frames. ( end auto-generated )
      See Also:
        `frameRate(float)`

    - #### frameCount

          public int frameCount

      ( begin auto-generated from frameCount.xml ) The system variable frameCount contains the number of frames displayed since the program started. Inside setup() the value is 0 and and after the first iteration of draw it is 1, etc. ( end auto-generated )
      See Also:
        `frameRate(float)`

    - #### finished

          public volatile boolean finished

      true if the sketch has stopped permanently.

    - #### paused

          public volatile boolean paused

      true if the animation thread is paused.

          public static final String ARGS_EDITOR_LOCATION

      Position of the upper-lefthand corner of the editor window that launched this applet.
      See Also:
        Constant Field Values

    - #### ARGS_EXTERNAL

          public static final String ARGS_EXTERNAL

      Location for where to position the applet window on screen.

      This is used by the editor to when saving the previous applet location, or could be used by other classes to launch at a specific position on-screen.

      See Also:
        Constant Field Values

    - #### ARGS_LOCATION

          public static final String ARGS_LOCATION

    - #### ARGS_SKETCH_FOLDER

          public static final String ARGS_SKETCH_FOLDER

      Allows the user or PdeEditor to set a specific sketch folder path.

      Used by PdeEditor to pass in the location where saveFrame() and all that stuff should write things.

      See Also:
        Constant Field Values

    - #### EXTERNAL_STOP

          public static final String EXTERNAL_STOP

      When run externally to a PdeEditor, this is sent by the applet when it quits.
      See Also:
        Constant Field Values

    - #### EXTERNAL_MOVE

          public static final String EXTERNAL_MOVE

      When run externally to a PDE Editor, this is sent by the applet whenever the window is moved.

      This is used so that the editor can re-open the sketch window in the same position as the user last left it.

      See Also:
        Constant Field Values

    - #### requestImageMax

          public int requestImageMax

      By trial and error, four image loading threads seem to work best when loading images from online. This is consistent with the number of open connections that web browsers will maintain. The variable is made public (however no accessor has been added since it's esoteric) if you really want to have control over the value used. For instance, when loading local files, it might be better to only have a single thread (or two) loading images so that you're disk isn't simply jumping around.

  - ### Constructor Detail

    - #### PApplet

          public PApplet()

  - ### Method Detail

    - #### init

          public void init()

      Applet initialization. This can do GUI work because the components have not been 'realized' yet: things aren't visible, displayed, etc.
      Overrides:
        `init` in class `Applet`

    - #### sketchQuality

          public int sketchQuality()

    - #### sketchWidth

          public int sketchWidth()

    - #### sketchHeight

          public int sketchHeight()

    - #### sketchRenderer

          public String sketchRenderer()

    - #### sketchFullScreen

          public boolean sketchFullScreen()

    - #### orientation

          public void orientation(int which)

    - #### start

          public void start()

      Called by the browser or applet viewer to inform this applet that it should start its execution. It is called after the init method and each time the applet is revisited in a Web page.

      Called explicitly via the first call to PApplet.paint(), because PAppletGL needs to have a usable screen before getting things rolling.
      Overrides:
        `start` in class `Applet`

    - #### stop

          public void stop()

      Called by the browser or applet viewer to inform this applet that it should stop its execution.

      Unfortunately, there are no guarantees from the Java spec when or if stop() will be called (i.e. on browser quit, or when moving between web pages), and it's not always called.
      Overrides:
        `stop` in class `Applet`

    - #### pause

          public void pause()

      Sketch has been paused. Called when switching tabs in a browser or swapping to a different application on Android. Also called just before quitting. Use to safely disable things like serial, sound, or sensors.

    - #### resume

          public void resume()

      Sketch has resumed. Called when switching tabs in a browser or swapping to this application on Android. Also called on startup. Use this to safely disable things like serial, sound, or sensors.

    - #### destroy

          public void destroy()

      Called by the browser or applet viewer to inform this applet that it is being reclaimed and that it should destroy any resources that it has allocated.

      destroy() supposedly gets called as the applet viewer is shutting down the applet. stop() is called first, and then destroy() to really get rid of things. no guarantees on when they're run (on browser quit, or when moving between pages), though.
      Overrides:
        `destroy` in class `Applet`

    - #### registerMethod

          public void registerMethod(String methodName,
                            Object target)

      Register a built-in event so that it can be fired for libraries, etc. Supported events include:
      - pre – at the very top of the draw() method (safe to draw)
      - draw – at the end of the draw() method (safe to draw)
      - post – after draw() has exited (not safe to draw)
      - pause – called when the sketch is paused
      - resume – called when the sketch is resumed
      - dispose – when the sketch is shutting down (definitely not safe to draw)
        In addition, the new (for 2.0) processing.event classes are passed to the following event types:
        - mouseEvent
        - keyEvent
        - touchEvent
        The older java.awt events are no longer supported. See the Library Wiki page for more details.
      Parameters:
        `methodName` - name of the method to be called
        `target` - the target object that should receive the event

    - #### unregisterMethod

    - #### setup

          public void setup()

      ( begin auto-generated from setup.xml ) The setup() function is called once when the program starts. It's used to define initial enviroment properties such as screen size and background color and to load media such as images and fonts as the program starts. There can only be one setup() function for each program and it shouldn't be called again after its initial execution. Note: Variables declared within setup() are not accessible within other functions, including draw(). ( end auto-generated )
      See Also:
        `size(int, int)`, `loop()`, `noLoop()`, `draw()`

    - #### draw

          public void draw()

      ( begin auto-generated from draw.xml ) Called directly after setup() and continuously executes the lines of code contained inside its block until the program is stopped or noLoop() is called. The draw() function is called automatically and should never be called explicitly. It should always be controlled with noLoop(), redraw() and loop(). After noLoop() stops the code in draw() from executing, redraw() causes the code inside draw() to execute once and loop() will causes the code inside draw() to execute continuously again. The number of times draw() executes in each second may be controlled with frameRate() function. There can only be one draw() function for each sketch and draw() must exist if you want the code to run continuously or to process events such as mousePressed(). Sometimes, you might have an empty call to draw() in your program as shown in the above example. ( end auto-generated )
      See Also:
        `setup()`, `loop()`, `noLoop()`, `redraw()`, `frameRate(float)`

    - #### size

          public void size(int w,
                  int h)

      ( begin auto-generated from size.xml ) Defines the dimension of the display window in units of pixels. The size() function must be the first line in setup(). If size() is not used, the default size of the window is 100x100 pixels. The system variables width and height are set by the parameters passed to this function.
      Do not use variables as the parameters to size() function, because it will cause problems when exporting your sketch. When variables are used, the dimensions of your sketch cannot be determined during export. Instead, employ numeric values in the size() statement, and then use the built-in width and height variables inside your program when the dimensions of the display window are needed.
      The size() function can only be used once inside a sketch, and cannot be used for resizing.
      renderer parameter selects which rendering engine to use. For example, if you will be drawing 3D shapes, use P3D, if you want to export images from a program as a PDF file use PDF. A brief description of the three primary renderers follows:
      P2D (Processing 2D) - The default renderer that supports two dimensional drawing.
      P3D (Processing 3D) - 3D graphics renderer that makes use of OpenGL-compatible graphics hardware.
      PDF - The PDF renderer draws 2D graphics directly to an Acrobat PDF file. This produces excellent results when you need vector shapes for high resolution output or printing. You must first use Import Library → PDF to make use of the library. More information can be found in the PDF library reference.
      The P3D renderer doesn't support strokeCap() or strokeJoin(), which can lead to ugly results when using strokeWeight(). (Issue 123)
      The maximum width and height is limited by your operating system, and is usually the width and height of your actual screen. On some machines it may simply be the number of pixels on your current screen, meaning that a screen of 800x600 could support size(1600, 300), since it's the same number of pixels. This varies widely so you'll have to try different rendering modes and sizes until you get what you're looking for. If you need something larger, use createGraphics to create a non-visible drawing surface.
      Again, the size() function must be the first line of the code (or first item inside setup). Any code that appears before the size() command may run more than once, which can lead to confusing results. ( end auto-generated )

      ### Advanced

      If using Java 1.3 or later, this will default to using PGraphics2, the Java2D-based renderer. If using Java 1.1, or if PGraphics2 is not available, then PGraphics will be used. To set your own renderer, use the other version of the size() method that takes a renderer as its last parameter.

      If called once a renderer has already been set, this will use the previous renderer and simply resize it.

      Parameters:
        `w` - width of the display window in units of pixels
        `h` - height of the display window in units of pixels

    - #### size

          public void size(int w,
                  int h,
                  String renderer)

      Parameters:
        `renderer` - Either P2D, P3D, or PDF

    - #### size

          public void size(int w,
                  int h,
                  String renderer,
                  String path)

    - #### createGraphics

          public PGraphics createGraphics(int w,
                                 int h)

    - #### createGraphics

          public PGraphics createGraphics(int w,
                                 int h,
                                 String renderer)

      ( begin auto-generated from createGraphics.xml ) Creates and returns a new PGraphics object of the types P2D or P3D. Use this class if you need to draw into an off-screen graphics buffer. The PDF renderer requires the filename parameter. The DXF renderer should not be used with createGraphics(), it's only built for use with beginRaw() and endRaw().
      It's important to call any drawing functions between beginDraw() and endDraw() statements. This is also true for any functions that affect drawing, such as smooth() or colorMode().
      the main drawing surface which is completely opaque, surfaces created with createGraphics() can have transparency. This makes it possible to draw into a graphics and maintain the alpha channel. By using save() to write a PNG or TGA file, the transparency of the graphics object will be honored. Note that transparency levels are binary: pixels are either complete opaque or transparent. For the time being, this means that text characters will be opaque blocks. This will be fixed in a future release (Issue 80). ( end auto-generated )

      ### Advanced

      Create an offscreen PGraphics object for drawing. This can be used for bitmap or vector images drawing or rendering.
      - Do not use "new PGraphicsXxxx()", use this method. This method ensures that internal variables are set up properly that tie the new graphics context back to its parent PApplet.
      - The basic way to create bitmap images is to use the saveFrame() function.
      - If you want to create a really large scene and write that, first make sure that you've allocated a lot of memory in the Preferences.
      - If you want to create images that are larger than the screen, you should create your own PGraphics object, draw to that, and use save().

             PGraphics big;

             void setup() {
               big = createGraphics(3000, 3000);

               big.beginDraw();
               big.background(128);
               big.line(20, 1800, 1800, 900);
               // etc..
               big.endDraw();

               // make sure the file is written to the sketch folder
               big.save("big.tif");
             }

      - It's important to always wrap drawing to createGraphics() with beginDraw() and endDraw() (beginFrame() and endFrame() prior to revision 0115). The reason is that the renderer needs to know when drawing has stopped, so that it can update itself internally. This also handles calling the defaults() method, for people familiar with that.
      - With Processing 0115 and later, it's possible to write images in formats other than the default .tga and .tiff. The exact formats and background information can be found in the developer's reference for PImage.save().
      Parameters:
        `w` - width in pixels
        `h` - height in pixels
        `renderer` - Either P2D, P3D, or PDF
      See Also:
        `PGraphics.PGraphics()`

    - #### createGraphics

          public PGraphics createGraphics(int w,
                                 int h,
                                 String renderer,
                                 String path)

      Create an offscreen graphics surface for drawing, in this case for a renderer that writes to a file (such as PDF or DXF).
      Parameters:
        `path` - the name of the file (can be an absolute or relative path)

    - #### createImage

          public PImage createImage(int w,
                           int h,
                           int format)

      ( begin auto-generated from createImage.xml ) Creates a new PImage (the datatype for storing images). This provides a fresh buffer of pixels to play with. Set the size of the buffer with the width and height parameters. The format parameter defines how the pixels are stored. See the PImage reference for more information.
      Be sure to include all three parameters, specifying only the width and height (but no format) will produce a strange error.
      Advanced users please note that createImage() should be used instead of the syntax `new PImage()`. ( end auto-generated )

      ### Advanced

      Preferred method of creating new PImage objects, ensures that a reference to the parent PApplet is included, which makes save() work without needing an absolute path.
      Parameters:
        `w` - width in pixels
        `h` - height in pixels
        `format` - Either RGB, ARGB, ALPHA (grayscale alpha channel)

    - #### handleDraw

          public void handleDraw()

    - #### canDraw

          public boolean canDraw()

      Not official API, not guaranteed to work in the future.

    - #### redraw

          public void redraw()

      ( begin auto-generated from redraw.xml ) Executes the code within draw() one time. This functions allows the program to update the display window only when necessary, for example when an event registered by mousePressed() or keyPressed() occurs.
      structuring a program, it only makes sense to call redraw() within events such as mousePressed(). This is because redraw() does not run draw() immediately (it only sets a flag that indicates an update is needed).
      redraw() within draw() has no effect because draw() is continuously called anyway. ( end auto-generated )
      See Also:
        `draw()`, `loop()`, `noLoop()`, `frameRate(float)`

    - #### loop

          public void loop()

      ( begin auto-generated from loop.xml ) Causes Processing to continuously execute the code within draw(). If noLoop() is called, the code in draw() stops executing. ( end auto-generated )
      See Also:
        `noLoop()`, `redraw()`, `draw()`

    - #### noLoop

          public void noLoop()

      ( begin auto-generated from noLoop.xml ) Stops Processing from continuously executing the code within draw(). If loop() is called, the code in draw() begin to run continuously again. If using noLoop() in setup(), it should be the last line inside the block.
      When noLoop() is used, it's not possible to manipulate or access the screen inside event handling functions such as mousePressed() or keyPressed(). Instead, use those functions to call redraw() or loop(), which will run draw(), which can update the screen properly. This means that when noLoop() has been called, no drawing can happen, and functions like saveFrame() or loadPixels() may not be used.
      Note that if the sketch is resized, redraw() will be called to update the sketch, even after noLoop() has been specified. Otherwise, the sketch would enter an odd state until loop() was called. ( end auto-generated )

    - #### postEvent

          public void postEvent(Event pe)

      Add an event to the internal event queue, or process it immediately if the sketch is not currently looping.

    - #### mousePressed

          public void mousePressed(MouseEvent e)

    - #### keyPressed

          public void keyPressed(KeyEvent e)

          public void keyPressed()

      ( begin auto-generated from keyPressed.xml ) The keyPressed() function is called once every time a key is pressed. The key that was pressed is stored in the key variable.
      For non-ASCII keys, use the keyCode variable. The keys included in the ASCII specification (BACKSPACE, TAB, ENTER, RETURN, ESC, and DELETE) do not require checking to see if they key is coded, and you should simply use the key variable instead of keyCode If you're making cross-platform projects, note that the ENTER key is commonly used on PCs and Unix and the RETURN key is used instead on Macintosh. Check for both ENTER and RETURN to make sure your program will work for all platforms.
      Because of how operating systems handle key repeats, holding down a key may cause multiple calls to keyPressed() (and keyReleased() as well). The rate of repeat is set by the operating system and how each computer is configured. ( end auto-generated )

      ### Advanced

      Called each time a single key on the keyboard is pressed. Because of how operating systems handle key repeats, holding down a key will cause multiple calls to keyPressed(), because the OS repeat takes over.

      Examples for key handling: (Tested on Windows XP, please notify if different on other platforms, I have a feeling Mac OS and Linux may do otherwise)

           1. Pressing 'a' on the keyboard:
              keyPressed  with key == 'a' and keyCode == 'A'
              keyTyped    with key == 'a' and keyCode ==  0
              keyReleased with key == 'a' and keyCode == 'A'

           2. Pressing 'A' on the keyboard:
              keyPressed  with key == 'A' and keyCode == 'A'
              keyTyped    with key == 'A' and keyCode ==  0
              keyReleased with key == 'A' and keyCode == 'A'

           3. Pressing 'shift', then 'a' on the keyboard (caps lock is off):
              keyPressed  with key == CODED and keyCode == SHIFT
              keyPressed  with key == 'A'   and keyCode == 'A'
              keyTyped    with key == 'A'   and keyCode == 0
              keyReleased with key == 'A'   and keyCode == 'A'
              keyReleased with key == CODED and keyCode == SHIFT

           4. Holding down the 'a' key.
              The following will happen several times,
              depending on your machine's "key repeat rate" settings:
              keyPressed  with key == 'a' and keyCode == 'A'
              keyTyped    with key == 'a' and keyCode ==  0
              When you finally let go, you'll get:
              keyReleased with key == 'a' and keyCode == 'A'

           5. Pressing and releasing the 'shift' key
              keyPressed  with key == CODED and keyCode == SHIFT
              keyReleased with key == CODED and keyCode == SHIFT
              (note there is no keyTyped)

           6. Pressing the tab key in an applet with Java 1.4 will
              normally do nothing, but PApplet dynamically shuts
              this behavior off if Java 1.4 is in use (tested 1.4.2_05 Windows).
              Java 1.1 (Microsoft VM) passes the TAB key through normally.
              Not tested on other platforms or for 1.3.

          public void keyTyped()

      ( begin auto-generated from keyTyped.xml ) The keyTyped() function is called once every time a key is pressed, but action keys such as Ctrl, Shift, and Alt are ignored. Because of how operating systems handle key repeats, holding down a key will cause multiple calls to keyTyped(), the rate is set by the operating system and how each computer is configured. ( end auto-generated )

        `focusLost` in interface `FocusListener`

    - #### millis

          public int millis()

      ( begin auto-generated from millis.xml ) Returns the number of milliseconds (thousandths of a second) since starting an applet. This information is often used for timing animation sequences. ( end auto-generated )

      ### Advanced

      This is a function, rather than a variable, because it may change multiple times per frame.

      See Also:
        `second()`, `minute()`, `hour()`, `day()`, `month()`, `year()`

    - #### second

          public static int second()

      ( begin auto-generated from second.xml ) Processing communicates with the clock on your computer. The second() function returns the current second as a value from 0 - 59. ( end auto-generated )
      See Also:
        `millis()`, `minute()`, `hour()`, `day()`, `month()`, `year()`

    - #### minute

          public static int minute()

      ( begin auto-generated from minute.xml ) Processing communicates with the clock on your computer. The minute() function returns the current minute as a value from 0 - 59. ( end auto-generated )
      See Also:
        `millis()`, `second()`, `hour()`, `day()`, `month()`, `year()`

    - #### hour

          public static int hour()

      ( begin auto-generated from hour.xml ) Processing communicates with the clock on your computer. The hour() function returns the current hour as a value from 0 - 23. ( end auto-generated )
      See Also:
        `millis()`, `second()`, `minute()`, `day()`, `month()`, `year()`

    - #### day

          public static int day()

      ( begin auto-generated from day.xml ) Processing communicates with the clock on your computer. The day() function returns the current day as a value from 1 - 31. ( end auto-generated )

      ### Advanced

      Get the current day of the month (1 through 31).

      If you're looking for the day of the week (M-F or whatever) or day of the year (1..365) then use java's Calendar.get()

      See Also:
        `millis()`, `second()`, `minute()`, `hour()`, `month()`, `year()`

    - #### month

          public static int month()

      ( begin auto-generated from month.xml ) Processing communicates with the clock on your computer. The month() function returns the current month as a value from 1 - 12. ( end auto-generated )
      See Also:
        `millis()`, `second()`, `minute()`, `hour()`, `day()`, `year()`

    - #### year

          public static int year()

      ( begin auto-generated from year.xml ) Processing communicates with the clock on your computer. The year() function returns the current year as an integer (2003, 2004, 2005, etc). ( end auto-generated ) The year() function returns the current year as an integer (2003, 2004, 2005, etc).
      See Also:
        `millis()`, `second()`, `minute()`, `hour()`, `day()`, `month()`

    - #### delay

          public void delay(int napTime)

      The delay() function causes the program to halt for a specified time. Delay times are specified in thousandths of a second. For example, running delay(3000) will stop the program for three seconds and delay(500) will stop the program for a half-second. The screen only updates when the end of draw() is reached, so delay() cannot be used to slow down drawing. For instance, you cannot use delay() to control the timing of an animation. The delay() function should only be used for pausing scripts (i.e. a script that needs to pause a few seconds before attempting a download, or a sketch that needs to wait a few milliseconds before reading from the serial port).

    - #### frameRate

          public void frameRate(float fps)

      ( begin auto-generated from frameRate.xml ) Specifies the number of frames to be displayed every second. If the processor is not fast enough to maintain the specified rate, it will not be achieved. For example, the function call frameRate(30) will attempt to refresh 30 times a second. It is recommended to set the frame rate within setup(). The default rate is 60 frames per second. ( end auto-generated )
      Parameters:
        `fps` - number of desired frames per second
      See Also:
        `setup()`, `draw()`, `loop()`, `noLoop()`, `redraw()`

    - #### param

          public String param(String name)

      Deprecated. no more applet support
      Reads the value of a param. Values are always read as a String so if you want them to be an integer or other datatype they must be converted. The param() function will only work in a web browser. The function should be called inside setup(), otherwise the applet may not yet be initialized and connected to its parent web browser.
      Parameters:
        `name` - name of the param to read

    - #### status

          public void status(String value)

      Deprecated. no more applet support

      ### Advanced

      Show status in the status bar of a web browser, or in the System.out console. Eventually this might show status in the p5 environment itself, rather than relying on the console.

    - #### link

          public void link(String url)

    - #### link

          public void link(String url,
                  String target)

      Deprecated. the 'target' parameter is no longer relevant with the removal of applets
      Links to a webpage either in the same window or in a new window. The complete URL must be specified.

      ### Advanced

      Link to an external page without all the muss.

      When run with an applet, uses the browser to open the url, for applications, attempts to launch a browser with the url.

      Works on Mac OS X and Windows. For Linux, use:

          open(new String[] { "firefox", url });

      or whatever you want as your browser, since Linux doesn't yet have a standard method for launching URLs.
      Parameters:
        `url` - the complete URL, as a String in quotes
        `target` - the name of the window in which to load the URL, as a String in quotes

    - #### open

          public static void open(String filename)

      ( begin auto-generated from open.xml ) Attempts to open an application or file using your platform's launcher. The file parameter is a String specifying the file name and location. The location parameter must be a full path name, or the name of an executable in the system's PATH. In most cases, using a full path is the best option, rather than relying on the system PATH. Be sure to make the file executable before attempting to open it (chmod +x).
      The args parameter is a String or String array which is passed to the command line. If you have multiple parameters, e.g. an application and a document, or a command with multiple switches, use the version that takes a String array, and place each individual item in a separate element.
      If args is a String (not an array), then it can only be a single file or application with no parameters. It's not the same as executing that String using a shell. For instance, open("jikes -help") will not work properly.
      This function behaves differently on each platform. On Windows, the parameters are sent to the Windows shell via "cmd /c". On Mac OS X, the "open" command is used (type "man open" in Terminal.app for documentation). On Linux, it first tries gnome-open, then kde-open, but if neither are available, it sends the command to the shell without any alterations.
      For users familiar with Java, this is not quite the same as Runtime.exec(), because the launcher command is prepended. Instead, the exec(String[]) function is a shortcut for Runtime.getRuntime.exec(String[]). ( end auto-generated )
      Parameters:
        `filename` - name of the file

    - #### open

          public static Process open(String[] argv)

      Launch a process using a platforms shell. This version uses an array to make it easier to deal with spaces in the individual elements. (This avoids the situation of trying to put single or double quotes around different bits).
      Parameters:
        `argv` - list of commands passed to the command line

    - #### exec

          public static Process exec(String[] argv)

    - #### die

          public void die(String what)

      Function for an applet/application to kill itself and display an error. Mostly this is here to be improved later.

    - #### die

          public void die(String what,
                 Exception e)

      Same as above but with an exception. Also needs work.

    - #### exit

          public void exit()

      ( begin auto-generated from exit.xml ) Quits/stops/exits the program. Programs without a draw() function exit automatically after the last line has run, but programs with draw() run continuously until the program is manually stopped or exit() is run.
      Rather than terminating immediately, exit() will cause the sketch to exit after draw() has completed (or after setup() completes if called during the setup() function).
      For Java programmers, this is not the same as System.exit(). Further, System.exit() should not be used because closing out an application while draw() is running may cause a crash (particularly with P3D). ( end auto-generated )

    - #### dispose

          public void dispose()

      Called to dispose of resources and shut down the sketch. Destroys the thread, dispose the renderer,and notify listeners.

      Not to be called or overriden by users. If called multiple times, will only notify listeners once. Register a dispose listener instead.

    - #### method

          public void method(String name)

      Call a method in the current class based on its name.

      Note that the function being called must be public. Inside the PDE, 'public' is automatically added, but when used without the preprocessor, (like from Eclipse) you'll have to do it yourself.

    - #### thread

          public void thread(String name)

      Launch a new thread and call the specified function from that new thread. This is a very simple way to do a thread without needing to get into classes, runnables, etc.

      Note that the function being called must be public. Inside the PDE, 'public' is automatically added, but when used without the preprocessor, (like from Eclipse) you'll have to do it yourself.

    - #### save

          public void save(String filename)

      ( begin auto-generated from save.xml ) Saves an image from the display window. Images are saved in TIFF, TARGA, JPEG, and PNG format depending on the extension within the filename parameter. For example, "image.tif" will have a TIFF image and "image.png" will save a PNG image. If no extension is included in the filename, the image will save in TIFF format and .tif will be added to the name. These files are saved to the sketch's folder, which may be opened by selecting "Show sketch folder" from the "Sketch" menu. It is not possible to use save() while running the program in a web browser.
      images saved from the main drawing window will be opaque. To save images without a background, use createGraphics(). ( end auto-generated )
      Parameters:
        `filename` - any sequence of letters and numbers
      See Also:
        `saveFrame()`, `createGraphics(int, int, String)`

    - #### saveFrame

          public void saveFrame()

    - #### saveFrame

          public void saveFrame(String filename)

      ( begin auto-generated from saveFrame.xml ) Saves a numbered sequence of images, one image each time the function is run. To save an image that is identical to the display window, run the function at the end of draw() or within mouse and key events such as mousePressed() and keyPressed(). If saveFrame() is called without parameters, it will save the files as screen-0000.tif, screen-0001.tif, etc. It is possible to specify the name of the sequence with the filename parameter and make the choice of saving TIFF, TARGA, PNG, or JPEG files with the ext parameter. These image sequences can be loaded into programs such as Apple's QuickTime software and made into movies. These files are saved to the sketch's folder, which may be opened by selecting "Show sketch folder" from the "Sketch" menu.
      It is not possible to use saveXxxxx() functions inside a web browser unless the sketch is signed applet. To save a file back to a server, see the save to web code snippet on the Processing Wiki.
      All images saved from the main drawing window will be opaque. To save images without a background, use createGraphics(). ( end auto-generated )
      Parameters:
        `filename` - any sequence of letters or numbers that ends with either ".tif", ".tga", ".jpg", or ".png"
      See Also:
        `save(String)`, `createGraphics(int, int, String, String)`

    - #### insertFrame

          public String insertFrame(String what)

      Check a string for #### signs to see if the frame number should be inserted. Used for functions like saveFrame() and beginRecord() to replace the # marks with the frame number. If only one # is used, it will be ignored, under the assumption that it's probably not intended to be the frame number.

    - #### cursor

          public void cursor(int kind)

      Set the cursor type
      Parameters:
        `kind` - either ARROW, CROSS, HAND, MOVE, TEXT, or WAIT

    - #### cursor

          public void cursor(PImage img)

      Replace the cursor with the specified PImage. The x- and y- coordinate of the center will be the center of the image.

    - #### cursor

          public void cursor(PImage img,
                    int x,
                    int y)

      ( begin auto-generated from cursor.xml ) Sets the cursor to a predefined symbol, an image, or makes it visible if already hidden. If you are trying to set an image as the cursor, it is recommended to make the size 16x16 or 32x32 pixels. It is not possible to load an image as the cursor if you are exporting your program for the Web and not all MODES work with all Web browsers. The values for parameters x and y must be less than the dimensions of the image.
      Setting or hiding the cursor generally does not work with "Present" mode (when running full-screen). ( end auto-generated )

      ### Advanced

      Set a custom cursor to an image with a specific hotspot. Only works with JDK 1.2 and later. Currently seems to be broken on Java 1.4 for Mac OS X

      Based on code contributed by Amit Pitaru, plus additional code to handle Java versions via reflection by Jonathan Feinberg. Reflection removed for release 0128 and later.

      Parameters:
        `img` - any variable of type PImage
        `x` - the horizontal active spot of the cursor
        `y` - the vertical active spot of the cursor
      See Also:
        `noCursor()`

    - #### cursor

          public void cursor()

      Show the cursor after noCursor() was called. Notice that the program remembers the last set cursor type

    - #### noCursor

          public void noCursor()

      ( begin auto-generated from noCursor.xml ) Hides the cursor from view. Will not work when running the program in a web browser or when running in full screen (Present) mode. ( end auto-generated )

      ### Advanced

      Hide the cursor by creating a transparent image and using it as a custom cursor.
      See Also:
        `cursor()`

    - #### print

          public static void print(byte what)

      ( begin auto-generated from print.xml ) Writes to the console area of the Processing environment. This is often helpful for looking at the data a program is producing. The companion function println() works like print(), but creates a new line of text for each call to the function. Individual elements can be separated with quotes ("") and joined with the addition operator (+).
      Beginning with release 0125, to print the contents of an array, use println(). There's no sensible way to do a print() of an array, because there are too many possibilities for how to separate the data (spaces, commas, etc). If you want to print an array as a single line, use join(). With join(), you can choose any delimiter you like and print() the result.
      Using print() on an object will output null, a memory location that may look like "@10be08," or the result of the toString() method from the object that's being printed. Advanced users who want more useful output when calling print() on their own classes can add a toString() method to the class that returns a String. ( end auto-generated )
      Parameters:
        `what` - data to print to console
      See Also:
        `println()`, `printArray(Object)`, `join(String[], char)`

    - #### print

          public static void print(Object... variables)

      Parameters:
        `variables` - list of data, separated by commas

    - #### println

          public static void println()

      ( begin auto-generated from println.xml ) Writes to the text area of the Processing environment's console. This is often helpful for looking at the data a program is producing. Each call to this function creates a new line of output. Individual elements can be separated with quotes ("") and joined with the string concatenation operator (+). See print() for more about what to expect in the output.
      println() on an array (by itself) will write the contents of the array to the console. This is often helpful for looking at the data a program is producing. A new line is put between each element of the array. This function can only print one dimensional arrays. For arrays with higher dimensions, the result will be closer to that of print(). ( end auto-generated )
      See Also:
        `print(byte)`, `printArray(Object)`

    - #### println

          public static void println(byte what)

      Parameters:
        `what` - data to print to console

    - #### println

          public static void println(Object... variables)

      Parameters:
        `variables` - list of data, separated by commas

    - #### println

          public static void println(Object what)

      For arrays, use printArray() instead. This function causes a warning because the new print(Object...) and println(Object...) functions can't be reliably bound by the compiler.

    - #### printArray

          public static void printArray(Object what)

      ( begin auto-generated from printArray.xml ) To come... ( end auto-generated )
      Parameters:
        `what` - one-dimensional array
      See Also:
        `print(byte)`, `println()`

    - #### debug

          public static void debug(String msg)

    - #### abs

          public static final float abs(float n)

      ( begin auto-generated from abs.xml ) Calculates the absolute value (magnitude) of a number. The absolute value of a number is always positive. ( end auto-generated )
      Parameters:
        `n` - number to compute

    - #### abs

          public static final int abs(int n)

    - #### sq

          public static final float sq(float n)

      ( begin auto-generated from sq.xml ) Squares a number (multiplies a number by itself). The result is always a positive number, as multiplying two negative numbers always yields a positive result. For example, -1 * -1 = 1. ( end auto-generated )
      Parameters:
        `n` - number to square
      See Also:
        `sqrt(float)`

    - #### sqrt

          public static final float sqrt(float n)

      ( begin auto-generated from sqrt.xml ) Calculates the square root of a number. The square root of a number is always positive, even though there may be a valid negative root. The square root s of number a is such that s*s = a. It is the opposite of squaring. ( end auto-generated )
      Parameters:
        `n` - non-negative number
      See Also:
        `pow(float, float)`, `sq(float)`

    - #### log

          public static final float log(float n)

      ( begin auto-generated from log.xml ) Calculates the natural logarithm (the base-e logarithm) of a number. This function expects the values greater than 0.0. ( end auto-generated )
      Parameters:
        `n` - number greater than 0.0

    - #### exp

          public static final float exp(float n)

      ( begin auto-generated from exp.xml ) Returns Euler's number e (2.71828...) raised to the power of the value parameter. ( end auto-generated )
      Parameters:
        `n` - exponent to raise

    - #### pow

          public static final float pow(float n,
                  float e)

      ( begin auto-generated from pow.xml ) Facilitates exponential expressions. The pow() function is an efficient way of multiplying numbers by themselves (or their reciprocal) in large quantities. For example, pow(3, 5) is equivalent to the expression 3*3*3*3*3 and pow(3, -5) is equivalent to 1 / 3*3*3*3*3. ( end auto-generated )
      Parameters:
        `n` - base of the exponential expression
        `e` - power by which to raise the base
      See Also:
        `sqrt(float)`

    - #### max

          public static final int max(int a,
                int b)

      ( begin auto-generated from max.xml ) Determines the largest value in a sequence of numbers. ( end auto-generated )
      Parameters:
        `a` - first number to compare
        `b` - second number to compare
      See Also:
        `min(float, float, float)`

    - #### max

                  float b,
                  float c)

    - #### max

          public static final int max(int[] list)

      Parameters:
        `list` - array of numbers to compare

          public static final int min(int a,
                int b)

      Find the maximum value in an array. Throws an ArrayIndexOutOfBoundsException if the array is length 0.
      Parameters:
        `list` - the source array
      Returns:
        The maximum value

    - #### min

          public static final float min(float a,
                  float b)

    - #### min

          public static final int min(int a,

      ( begin auto-generated from mag.xml ) Calculates the magnitude (or length) of a vector. A vector is a direction in space commonly used in computer graphics and linear algebra. Because it has no "start" position, the magnitude of a vector can be thought of as the distance from coordinate (0,0) to its (x,y) value. Therefore, mag() is a shortcut for writing "dist(0, 0, x, y)". ( end auto-generated )

                   float amt)

      ( begin auto-generated from lerp.xml ) Calculates a number between two numbers at a specific increment. The amt parameter is the amount to interpolate between the two values where 0.0 equal to the first point, 0.1 is very near the first point, 0.5 is half-way in between, etc. The lerp function is convenient for creating motion along a straight path and for drawing dotted lines. ( end auto-generated )

      ( begin auto-generated from norm.xml ) Normalizes a number from another range into a value between 0 and 1.
      Identical to map(value, low, high, 0, 1);
      Numbers outside the range are not clamped to 0 and 1, because out-of-range values are often intentional and useful. ( end auto-generated )
      Parameters:
        `value` - the incoming value to be converted
        `start` - lower bound of the value's current range

                  float stop2)

      ( begin auto-generated from map.xml ) Re-maps a number from one range to another. In the example above, the number '25' is converted from a value in the range 0..100 into a value that ranges from the left edge (0) to the right edge (width) of the screen.
      Numbers outside the range are not clamped to 0 and 1, because out-of-range values are often intentional and useful. ( end auto-generated )
      Parameters:

    - #### randomGaussian

          public final float randomGaussian()

      ( begin auto-generated from randomGaussian.xml ) Returns a float from a random series of numbers having a mean of 0 and standard deviation of 1. Each time the randomGaussian() function is called, it returns a number fitting a Gaussian, or normal, distribution. There is theoretically no minimum or maximum value that randomGaussian() might return. Rather, there is just a very low probability that values far from the mean will be returned; and a higher probability that numbers near the mean will be returned. ( end auto-generated )

        `random(float,float)`, `noise(float, float, float)`

    - #### random

          public final float random(float low,
                     float high)

      ( begin auto-generated from random.xml ) Generates random numbers. Each time the random() function is called, it returns an unexpected value within the specified range. If one parameter is passed to the function it will return a float between zero and the value of the high parameter. The function call random(5) returns values between 0 and 5 (starting at zero, up to but not including 5). If two parameters are passed, it will return a float with a value between the the parameters. The function call random(-5, 10.2) returns values starting at -5 up to (but not including) 10.2. To convert a floating-point random number to an integer, use the int() function. ( end auto-generated )
      Parameters:
        `low` - lower limit
        `high` - upper limit

        `randomSeed(long)`, `noise(float, float, float)`

    - #### randomSeed

          public final void randomSeed(long seed)

      ( begin auto-generated from randomSeed.xml ) Sets the seed value for random(). By default, random() produces different results each time the program is run. Set the value parameter to a constant to return the same pseudo-random numbers each time the software is run. ( end auto-generated )
      Parameters:

      See Also:
        `random(float,float)`, `noise(float, float, float)`, `noiseSeed(long)`

    - #### noise

          public float noise(float x,
                    float y)

    - #### noise

          public float noise(float x,
                    float y,
                    float z)

      ( begin auto-generated from noise.xml ) Returns the Perlin noise value at specified coordinates. Perlin noise is a random sequence generator producing a more natural ordered, harmonic succession of numbers compared to the standard random() function. It was invented by Ken Perlin in the 1980s and been used since in graphical applications to produce procedural textures, natural motion, shapes, terrains etc.
      The main difference to the random() function is that Perlin noise is defined in an infinite n-dimensional space where each pair of coordinates corresponds to a fixed semi-random value (fixed only for the lifespan of the program). The resulting value will always be between 0.0 and 1.0. Processing can compute 1D, 2D and 3D noise, depending on the number of coordinates given. The noise value can be animated by moving through the noise space as demonstrated in the example above. The 2nd and 3rd dimension can also be interpreted as time.
      The actual noise is structured similar to an audio signal, in respect to the function's use of frequencies. Similar to the concept of harmonics in physics, perlin noise is computed over several octaves which are added together for the final result.
      Another way to adjust the character of the resulting sequence is the scale of the input coordinates. As the function works within an infinite space the value of the coordinates doesn't matter as such, only the distance between successive coordinates does (eg. when using noise() within a loop). As a general rule the smaller the difference between coordinates, the smoother the resulting noise sequence will be. Steps of 0.005-0.03 work best for most applications, but this will differ depending on use. ( end auto-generated )
      Parameters:
        `x` - x-coordinate in noise space
        `y` - y-coordinate in noise space
        `z` - z-coordinate in noise space
      See Also:
        `noiseSeed(long)`, `noiseDetail(int, float)`, `random(float,float)`

    - #### noiseDetail

          public void noiseDetail(int lod)

      ( begin auto-generated from noiseDetail.xml ) Adjusts the character and level of detail produced by the Perlin noise function. Similar to harmonics in physics, noise is computed over several octaves. Lower octaves contribute more to the output signal and as such define the overal intensity of the noise, whereas higher octaves create finer grained details in the noise sequence. By default, noise is computed over 4 octaves with each octave contributing exactly half than its predecessor, starting at 50% strength for the 1st octave. This falloff amount can be changed by adding an additional function parameter. Eg. a falloff factor of 0.75 means each octave will now have 75% impact (25% less) of the previous lower octave. Any value between 0.0 and 1.0 is valid, however note that values greater than 0.5 might result in greater than 1.0 values returned by noise().
      By changing these parameters, the signal created by the noise() function can be adapted to fit very specific needs and characteristics. ( end auto-generated )
      Parameters:
        `lod` - number of octaves to be used by the noise
        `falloff` - falloff factor for each octave
      See Also:
        `noise(float, float, float)`

    - #### noiseDetail

          public void noiseDetail(int lod,

      Parameters:
        `falloff` - falloff factor for each octave

    - #### noiseSeed

          public void noiseSeed(long seed)

      ( begin auto-generated from noiseSeed.xml ) Sets the seed value for noise(). By default, noise() produces different results each time the program is run. Set the value parameter to a constant to return the same pseudo-random numbers each time the software is run. ( end auto-generated )
      Parameters:
        `seed` - seed value
      See Also:
        `noise(float, float, float)`, `noiseDetail(int, float)`, `random(float,float)`, `randomSeed(long)`

    - #### loadImage

          public PImage loadImage(String filename)

      ( begin auto-generated from loadImage.xml ) Loads an image into a variable of type PImage. Four types of images ( .gif, .jpg, .tga, .png) images may be loaded. To load correctly, images must be located in the data directory of the current sketch. In most cases, load all images in setup() to preload them at the start of the program. Loading images inside draw() will reduce the speed of a program.
      filename parameter can also be a URL to a file found online. For security reasons, a Processing sketch found online can only download files from the same server from which it came. Getting around this restriction requires a signed applet.
      extension parameter is used to determine the image type in cases where the image filename does not end with a proper extension. Specify the extension as the second parameter to loadImage(), as shown in the third example on this page.
      an image is not loaded successfully, the null value is returned and an error message will be printed to the console. The error message does not halt the program, however the null value may cause a NullPointerException if your code does not check whether the value returned from loadImage() is null.
      on the type of error, a PImage object may still be returned, but the width and height of the image will be set to -1. This happens if bad image data is returned or cannot be decoded properly. Sometimes this happens with image URLs that produce a 403 error or that redirect to a password prompt, because loadImage() will attempt to interpret the HTML as image data. ( end auto-generated )
      Parameters:
        `filename` - name of file to load, can be .gif, .jpg, .tga, or a handful of other image types depending on your platform

          public PImage loadImage(String filename,

    - #### requestImage

          public PImage requestImage(String filename,
                            String extension)

      ( begin auto-generated from requestImage.xml ) This function load images on a separate thread so that your sketch does not freeze while images load during setup(). While the image is loading, its width and height will be 0. If an error occurs while loading the image, its width and height will be set to -1. You'll know when the image has loaded properly because its width and height will be greater than 0. Asynchronous image loading (particularly when downloading from a server) can dramatically improve performance.
      extension parameter is used to determine the image type in cases where the image filename does not end with a proper extension. Specify the extension as the second parameter to requestImage(). ( end auto-generated )
      Parameters:
        `filename` - name of the file to load, can be .gif, .jpg, .tga, or a handful of other image types depending on your platform

      Options may contain "header", "tsv", "csv", or "bin" separated by commas. Another option is "dictionary=filename.tsv", which allows users to specify a "dictionary" file that contains a mapping of the column titles and the data types used in the table file. This can be far more efficient (in terms of speed and memory usage) for loading and parsing tables. The dictionary file can only be tab separated values (.tsv) and its extension will be ignored. This option was added in Processing 2.0.2.

        `options` - can be one of "tsv", "csv", "bin", or "html"

    - #### loadFont

          public PFont loadFont(String filename)

      ( begin auto-generated from loadFont.xml ) Loads a font into a variable of type PFont. To load correctly, fonts must be located in the data directory of the current sketch. To create a font to use with Processing, select "Create Font..." from the Tools menu. This will create a font in the format Processing requires and also adds it to the current sketch's data directory.
      Like loadImage() and other functions that load data, the loadFont() function should not be used inside draw(), because it will slow down the sketch considerably, as the font will be re-loaded from the disk (or network) on each frame.
      For most renderers, Processing displays fonts using the .vlw font format, which uses images for each letter, rather than defining them through vector data. When hint(ENABLE_NATIVE_FONTS) is used with the JAVA2D renderer, the native version of a font will be used if it is installed on the user's machine.
      Using createFont() (instead of loadFont) enables vector data to be used with the JAVA2D (default) renderer setting. This can be helpful when many font sizes are needed, or when using any renderer based on JAVA2D, such as the PDF library. ( end auto-generated )
      Parameters:
        `filename` - name of the font to load
      See Also:
        `PFont`, `PGraphics.textFont(PFont, float)`, `createFont(String, float, boolean, char[])`

    - #### createFont

          public PFont createFont(String name,
                         float size)

    - #### createFont

          public PFont createFont(String name,
                         float size,
                         boolean smooth)

    - #### createFont

          public PFont createFont(String name,
                         float size,
                         boolean smooth,
                         char[] charset)

      ( begin auto-generated from createFont.xml ) Dynamically converts a font to the format used by Processing from either a font name that's installed on the computer, or from a .ttf or .otf file inside the sketches "data" folder. This function is an advanced feature for precise control. On most occasions you should create fonts through selecting "Create Font..." from the Tools menu.
      Use the PFont.list() method to first determine the names for the fonts recognized by the computer and are compatible with this function. Because of limitations in Java, not all fonts can be used and some might work with one operating system and not others. When sharing a sketch with other people or posting it on the web, you may need to include a .ttf or .otf version of your font in the data directory of the sketch because other people might not have the font installed on their computer. Only fonts that can legally be distributed should be included with a sketch.
      The size parameter states the font size you want to generate. The smooth parameter specifies if the font should be antialiased or not, and the charset parameter is an array of chars that specifies the characters to generate.
      This function creates a bitmapped version of a font in the same manner as the Create Font tool. It loads a font by name, and converts it to a series of images based on the size of the font. When possible, the text() function will use a native font rather than the bitmapped version created behind the scenes with createFont(). For instance, when using P2D, the actual native version of the font will be employed by the sketch, improving drawing quality and performance. With the P3D renderer, the bitmapped version will be used. While this can drastically improve speed and appearance, results are poor when exporting if the sketch does not include the .otf or .ttf file, and the requested font is not available on the machine running the sketch. ( end auto-generated )
      Parameters:
        `name` - name of the font to load
        `size` - point size of the font
        `smooth` - true for an antialiased font, false for aliased
        `charset` - array containing characters to be generated

        `PFont`, `PGraphics.textFont(PFont, float)`, `PGraphics#text(String, float, float, float, float, float)`, `loadFont(String)`

    - #### selectInput

          public void selectInput(String prompt,
                         String callback)

      Open a platform-specific file chooser dialog to select a file for input. After the selection is made, the selected File will be passed to the 'callback' function. If the dialog is closed or canceled, null will be sent to the function, so that the program is not waiting for additional input. The callback is necessary because of how threading works.

           void setup() {
             selectInput("Select a file to process:", "fileSelected");
           }

           void fileSelected(File selection) {
             if (selection == null) {
               println("Window was closed or the user hit cancel.");
             } else {
               println("User selected " + fileSeleted.getAbsolutePath());
             }
           }

      For advanced users, the method must be 'public', which is true for all methods inside a sketch when run from the PDE, but must explicitly be set when using Eclipse or other development environments.
      Parameters:
        `prompt` - message to the user
        `callback` - name of the method to be called when the selection is made

      Returns:
        an extension, skipping past .gz if it's present

    - #### createReader

          public BufferedReader createReader(String filename)

      ( begin auto-generated from createReader.xml ) Creates a BufferedReader object that can be used to read files line-by-line as individual String objects. This is the complement to the createWriter() function.
      Starting with Processing release 0134, all files loaded and saved by the Processing API use UTF-8 encoding. In previous releases, the default encoding for your platform was used, which causes problems when files are moved to other platforms. ( end auto-generated )
      Parameters:
        `filename` - name of the file to be opened
      See Also:
        `BufferedReader`, `createWriter(String)`, `PrintWriter`

    - #### createReader

          public static BufferedReader createReader(File file)

    - #### createReader

          public static BufferedReader createReader(InputStream input)

    - #### createWriter

          public PrintWriter createWriter(String filename)

      ( begin auto-generated from createWriter.xml ) Creates a new file in the sketch folder, and a PrintWriter object to write to it. For the file to be made correctly, it should be flushed and must be closed with its flush() and close() methods (see above example).
      Starting with Processing release 0134, all files loaded and saved by the Processing API use UTF-8 encoding. In previous releases, the default encoding for your platform was used, which causes problems when files are moved to other platforms. ( end auto-generated )
      Parameters:
        `filename` - name of the file to be created
      See Also:
        `PrintWriter`, `createReader(java.lang.String)`, `BufferedReader`

    - #### createWriter

          public static PrintWriter createWriter(File file)

    - #### createWriter

          public static PrintWriter createWriter(OutputStream output)

    - #### openStream

          public InputStream openStream(String filename)

      Deprecated. As of release 0136, use createInput() instead.

    - #### createInput

          public InputStream createInput(String filename)

      ( begin auto-generated from createInput.xml ) This is a function for advanced programmers to open a Java InputStream. It's useful if you want to use the facilities provided by PApplet to easily open files from the data folder or from a URL, but want an InputStream object so that you can use other parts of Java to take more control of how the stream is read.
      The filename passed in can be:
      - A URL, for instance openStream("http://processing.org/")
      - A file in the sketch's data folder
      - The full path to a file to be opened locally (when running as an application)
      If the requested item doesn't exist, null is returned. If not online, this will also check to see if the user is asking for a file whose name isn't properly capitalized. If capitalization is different, an error will be printed to the console. This helps prevent issues that appear when a sketch is exported to the web, where case sensitivity matters, as opposed to running from inside the Processing Development Environment on Windows or Mac OS, where case sensitivity is preserved but ignored.
      If the file ends with .gz, the stream will automatically be gzip decompressed. If you don't want the automatic decompression, use the related function createInputRaw().
      In earlier releases, this function was called openStream().
      ( end auto-generated )

      ### Advanced

      Simplified method to open a Java InputStream.

      This method is useful if you want to use the facilities provided by PApplet to easily open things from the data folder or from a URL, but want an InputStream object so that you can use other Java methods to take more control of how the stream is read.

      If the requested item doesn't exist, null is returned. (Prior to 0096, die() would be called, killing the applet)

      For 0096+, the "data" folder is exported intact with subfolders, and openStream() properly handles subdirectories from the data folder

      If not online, this will also check to see if the user is asking for a file whose name isn't properly capitalized. This helps prevent issues when a sketch is exported to the web, where case sensitivity matters, as opposed to Windows and the Mac OS default where case sensitivity is preserved but ignored.

      It is strongly recommended that libraries use this method to open data files, so that the loading sequence is handled in the same way as functions like loadBytes(), loadImage(), etc.

      The filename passed in can be:

      - A URL, for instance openStream("http://processing.org/");
      - A file in the sketch's data folder
      - Another file to be opened locally (when running as an application)
      Parameters:
        `filename` - the name of the file to use as input
      See Also:
        `createOutput(String)`, `PApplet#selectOutput(String)`, `PApplet#selectInput(String)`

    - #### createInputRaw

          public InputStream createInputRaw(String filename)

      Call openStream() without automatic gzip decompression.

    - #### createInput

          public static InputStream createInput(File file)

    - #### loadBytes

          public byte[] loadBytes(String filename)

      ( begin auto-generated from loadBytes.xml ) Reads the contents of a file or url and places it in a byte array. If a file is specified, it must be located in the sketch's "data" directory/folder.
      The filename parameter can also be a URL to a file found online. For security reasons, a Processing sketch found online can only download files from the same server from which it came. Getting around this restriction requires a signed applet. ( end auto-generated )
      Parameters:
        `filename` - name of a file in the data folder or a URL.
      See Also:
        `loadStrings(String)`, `saveStrings(String, String[])`, `saveBytes(String, byte[])`

    - #### loadBytes

          public static byte[] loadBytes(InputStream input)

    - #### loadBytes

          public static byte[] loadBytes(File file)

    - #### loadStrings

          public static String[] loadStrings(File file)

    - #### loadStrings

          public String[] loadStrings(String filename)

      ( begin auto-generated from loadStrings.xml ) Reads the contents of a file or url and creates a String array of its individual lines. If a file is specified, it must be located in the sketch's "data" directory/folder.
      The filename parameter can also be a URL to a file found online. For security reasons, a Processing sketch found online can only download files from the same server from which it came. Getting around this restriction requires a signed applet.
      If the file is not available or an error occurs, null will be returned and an error message will be printed to the console. The error message does not halt the program, however the null value may cause a NullPointerException if your code does not check whether the value returned is null.
      Starting with Processing release 0134, all files loaded and saved by the Processing API use UTF-8 encoding. In previous releases, the default encoding for your platform was used, which causes problems when files are moved to other platforms. ( end auto-generated )

      ### Advanced

      Load data from a file and shove it into a String array.

      Exceptions are handled internally, when an error, occurs, an exception is printed to the console and 'null' is returned, but the program continues running. This is a tradeoff between 1) showing the user that there was a problem but 2) not requiring that all i/o code is contained in try/catch blocks, for the sake of new users (or people who are just trying to get things done in a "scripting" fashion. If you want to handle exceptions, use Java methods for I/O.

      Parameters:
        `filename` - name of the file or url to load
      See Also:
        `loadBytes(String)`, `saveStrings(String, String[])`, `saveBytes(String, byte[])`

    - #### loadStrings

          public static String[] loadStrings(InputStream input)

    - #### loadStrings

          public static String[] loadStrings(BufferedReader reader)

    - #### createOutput

          public OutputStream createOutput(String filename)

      ( begin auto-generated from createOutput.xml ) Similar to createInput(), this creates a Java OutputStream for a given filename or path. The file will be created in the sketch folder, or in the same folder as an exported application.
      If the path does not exist, intermediate folders will be created. If an exception occurs, it will be printed to the console, and null will be returned.
      This function is a convenience over the Java approach that requires you to 1) create a FileOutputStream object, 2) determine the exact file location, and 3) handle exceptions. Exceptions are handled internally by the function, which is more appropriate for "sketch" projects.
      If the output filename ends with .gz, the output will be automatically GZIP compressed as it is written. ( end auto-generated )
      Parameters:
        `filename` - name of the file to open
      See Also:
        `createInput(String)`, `PApplet#selectOutput()`

    - #### createOutput

          public static OutputStream createOutput(File file)

    - #### saveStream

          public boolean saveStream(String target,
                           String source)

      ( begin auto-generated from saveStream.xml ) Save the contents of a stream to a file in the sketch folder. This is basically saveBytes(blah, loadBytes()), but done more efficiently (and with less confusing syntax).
      When using the targetFile parameter, it writes to a File object for greater control over the file location. (Note that unlike some other functions, this will not automatically compress or uncompress gzip files.) ( end auto-generated )
      Parameters:
        `target` - name of the file to write to
        `source` - location to read from (a filename, path, or URL)
      See Also:
        `createOutput(String)`

    - #### saveStream

          public boolean saveStream(File target,
                           String source)

      Identical to the other saveStream(), but writes to a File object, for greater control over the file location.

      Note that unlike other api methods, this will not automatically compress or uncompress gzip files.

    - #### saveStream

          public boolean saveStream(String target,
                           InputStream source)

                           InputStream source)

    - #### saveStream

          public static void saveStream(OutputStream target,
                        InputStream source)
                                 throws IOException

      Throws:
        `IOException`

    - #### saveBytes

          public void saveBytes(String filename,
                       byte[] data)

      ( begin auto-generated from saveBytes.xml ) Opposite of loadBytes(), will write an entire array of bytes to a file. The data is saved in binary format. This file is saved to the sketch's folder, which is opened by selecting "Show sketch folder" from the "Sketch" menu.
      It is not possible to use saveXxxxx() functions inside a web browser unless the sketch is signed applet. To save a file back to a server, see the save to web code snippet on the Processing Wiki. ( end auto-generated )
      Parameters:
        `filename` - name of the file to write to
        `data` - array of bytes to be written
      See Also:
        `loadStrings(String)`, `loadBytes(String)`, `saveStrings(String, String[])`

      ( begin auto-generated from saveStrings.xml ) Writes an array of strings to a file, one line per string. This file is saved to the sketch's folder, which is opened by selecting "Show sketch folder" from the "Sketch" menu.
      It is not possible to use saveXxxxx() functions inside a web browser unless the sketch is signed applet. To save a file back to a server, see the save to web code snippet on the Processing Wiki.
      Starting with Processing 1.0, all files loaded and saved by the Processing API use UTF-8 encoding. In previous releases, the default encoding for your platform was used, which causes problems when files are moved to other platforms. ( end auto-generated )
      Parameters:
        `filename` - filename for output
        `data` - string array to be written
      See Also:
        `loadStrings(String)`, `loadBytes(String)`, `saveBytes(String, byte[])`

    - #### saveStrings

                         String[] data)

    - #### sketchPath

          public String sketchPath(String where)

      Prepend the sketch folder path to the filename (or path) that is passed in. External libraries should use this function to save to the sketch folder.

      Note that when running as an applet inside a web browser, the sketchPath will be set to null, because security restrictions prevent applets from accessing that information.

      This will also cause an error if the sketch is not inited properly, meaning that init() was never called on the PApplet when hosted my some other main() or by other code. For proper use of init(), see the examples in the main description text for PApplet.

    - #### sketchFile

          public File sketchFile(String where)

    - #### savePath

          public String savePath(String where)

      Returns a path inside the applet folder to save to. Like sketchPath(), but creates any in-between folders so that things save properly.

      All saveXxxx() functions use the path to the sketch folder, rather than its data folder. Once exported, the data folder will be found inside the jar file of the exported application or applet. In this case, it's not possible to save data into the jar file, because it will often be running from a server, or marked in-use if running from a local file system. With this in mind, saving to the data path doesn't make sense anyway. If you know you're running locally, and want to save to the data folder, use `saveXxxx("data/blah.dat")`.

    - #### saveFile

          public File saveFile(String where)

      Identical to savePath(), but returns a File object.

    - #### desktopFile

          public static File desktopFile(String what)

      Not a supported function. For testing use only.

    - #### desktopPath

          public static String desktopPath(String what)

      Not a supported function. For testing use only.

    - #### dataPath

          public String dataPath(String where)

      Return a full path to an item in the data folder.

      This is only available with applications, not applets or Android. On Windows and Linux, this is simply the data folder, which is located in the same directory as the EXE file and lib folders. On Mac OS X, this is a path to the data folder buried inside Contents/Java. For the latter point, that also means that the data folder should not be considered writable. Use sketchPath() for now, or inputPath() and outputPath() once they're available in the 2.0 release.

      dataPath() is not supported with applets because applets have their data folder wrapped into the JAR file. To read data from the data folder that works with an applet, you should use other methods such as createInput(), createReader(), or loadStrings().

    - #### dataFile

          public File dataFile(String where)

      Return a full path to an item in the data folder as a File object. See the dataPath() method for more information.

    - #### createPath

          public static void createPath(String path)

      Takes a path and creates any in-between folders if they don't already exist. Useful when trying to save to a subfolder that may not actually exist.

    - #### sort

          public static byte[] sort(byte[] list)

      ( begin auto-generated from sort.xml ) Sorts an array of numbers from smallest to largest and puts an array of words in alphabetical order. The original array is not modified, a re-ordered array is returned. The count parameter states the number of elements to sort. For example if there are 12 elements in an array and if count is the value 5, only the first five elements on the array will be sorted. ( end auto-generated )

                       int srcPosition,
                       Object dst,
                       int dstPosition,
                       int length)

      ( begin auto-generated from arrayCopy.xml ) Copies an array (or part of an array) to another array. The src array is copied to the dst array, beginning at the position specified by srcPos and into the position specified by dstPos. The number of elements to copy is determined by length. The simplified version with two arguments copies an entire array to another of the same size. It is equivalent to "arrayCopy(src, 0, dst, 0, src.length)". This function is far more efficient for copying array data than iterating through a for and copying each element. ( end auto-generated )
      Parameters:
        `src` - the source array
        `srcPosition` - starting position in the source array
        `dst` - the destination array of the same data type as the source array
        `dstPosition` - starting position in the destination array
        `length` - number of array elements to be copied

    - #### expand

          public static boolean[] expand(boolean[] list)

      ( begin auto-generated from expand.xml ) Increases the size of an array. By default, this function doubles the size of the array, but the optional newSize parameter provides precise control over the increase in size.
      When using an array of objects, the data returned from the function must be cast to the object array's data type. For example: SomeClass[] items = (SomeClass[]) expand(originalArray). ( end auto-generated )

      ( begin auto-generated from subset.xml ) Extracts an array of elements from an existing array. The array parameter defines the array from which the elements will be copied and the offset and length parameters determine which elements to extract. If no length is given, elements will be extracted from the offset to the end of the array. When specifying the offset remember the first array element is 0. This function does not change the source array.
      When using an array of objects, the data returned from the function must be cast to the object array's data type. For example: SomeClass[] items = (SomeClass[]) subset(originalArray, 0, 4). ( end auto-generated )

    - #### join

          public static String join(String[] list,
                    char separator)

      ( begin auto-generated from join.xml ) Combines an array of Strings into one String, each separated by the character(s) used for the separator parameter. To join arrays of ints or floats, it's necessary to first convert them to strings using nf() or nfs(). ( end auto-generated )
      Parameters:
        `list` - array of Strings
        `separator` - char or String to be placed between each item

          public static String[] splitTokens(String value,
                             String delim)

      ( begin auto-generated from splitTokens.xml ) The splitTokens() function splits a String at one or many character "tokens." The tokens parameter specifies the character or characters to be used as a boundary.
      If no tokens character is specified, any whitespace character is used to split. Whitespace characters include tab (\\t), line feed (\\n), carriage return (\\r), form feed (\\f), and space. To convert a String to an array of integers or floats, use the datatype conversion functions int() and float() to convert the array of Strings. ( end auto-generated )
      Parameters:
        `value` - the String to be split
        `delim` - list of individual characters that will be used as separators
      See Also:
        `split(String, String)`, `join(String[], String)`, `trim(String)`

    - #### split

          public static String[] split(String value,
                       char delim)

      ( begin auto-generated from split.xml ) The split() function breaks a string into pieces using a character or string as the divider. The delim parameter specifies the character or characters that mark the boundaries between each piece. A String[] array is returned that contains each of the pieces.
      If the result is a set of numbers, you can convert the String[] array to to a float[] or int[] array using the datatype conversion functions int() and float() (see example above).
      The splitTokens() function works in a similar fashion, except that it splits using a range of characters instead of a specific character or sequence. ( end auto-generated )
      Parameters:
        `value` - the String to be split
        `delim` - the character or String used to separate the data

    - #### split

          public static String[] split(String value,
                       String delim)

    - #### match

          public static String[] match(String str,
                       String regexp)

      ( begin auto-generated from match.xml ) The match() function is used to apply a regular expression to a piece of text, and return matching groups (elements found inside parentheses) as a String array. No match will return null. If no groups are specified in the regexp, but the sequence matches, an array of length one (with the matched text as the first element of the array) will be returned.
      To use the function, first check to see if the result is null. If the result is null, then the sequence did not match. If the sequence did match, an array is returned. If there are groups (specified by sets of parentheses) in the regexp, then the contents of each will be returned in the array. Element [0] of a regexp match returns the entire matching string, and the match groups start at element [1] (the first group is [1], the second [2], and so on).
      The syntax can be found in the reference for Java's Pattern class. For regular expression syntax, read the Java Tutorial on the topic. ( end auto-generated )
      Parameters:
        `str` - the String to be searched
        `regexp` - the regexp to be used for matching
      See Also:
        `matchAll(String, String)`, `split(String, String)`, `splitTokens(String, String)`, `join(String[], String)`, `trim(String)`

    - #### matchAll

          public static String[][] matchAll(String str,
                            String regexp)

      ( begin auto-generated from matchAll.xml ) This function is used to apply a regular expression to a piece of text, and return a list of matching groups (elements found inside parentheses) as a two-dimensional String array. No matches will return null. If no groups are specified in the regexp, but the sequence matches, a two dimensional array is still returned, but the second dimension is only of length one.
      To use the function, first check to see if the result is null. If the result is null, then the sequence did not match at all. If the sequence did match, a 2D array is returned. If there are groups (specified by sets of parentheses) in the regexp, then the contents of each will be returned in the array. Assuming, a loop with counter variable i, element [i][0] of a regexp match returns the entire matching string, and the match groups start at element [i][1] (the first group is [i][1], the second [i][2], and so on).
      The syntax can be found in the reference for Java's Pattern class. For regular expression syntax, read the Java Tutorial on the topic. ( end auto-generated )
      Parameters:
        `str` - the String to be searched
        `regexp` - the regexp to be used for matching

    - #### parseBoolean

          public static final boolean parseBoolean(int what)

      Convert an integer to a boolean. Because of how Java handles upgrading numbers, this will also cover byte and char (as they will upgrade to an int without any sort of explicit cast).

      The preprocessor will convert boolean(what) to parseBoolean(what).

      Returns:
        false if 0, true if any other number

    - #### parseBoolean

          public static final boolean parseBoolean(String what)

      Convert the string "true" or "false" to a boolean.

        true if 'what' is "true" or "TRUE", false otherwise

    - #### parseBoolean

          public static final boolean[] parseBoolean(int[] what)

      Convert an int array to a boolean array. An int equal to zero will return false, and any other value will return true.
      Returns:

      Note that parseInt() will un-sign a signed byte value.

    - #### parseInt

          public static final int parseInt(char what)

      Note that parseInt('5') is unlike String in the sense that it won't return 5, but the ascii value. This is because ((int) someChar) returns the ascii value, and parseInt() is just longhand for the cast.

    - #### parseInt

          public static final int parseInt(float what)

      Same as floor(), or an (int) cast.

    - #### parseInt

      Make an array of int elements from an array of String objects. If the String can't be parsed as a number, it will be set to zero. String s[] = { "1", "300", "44" }; int numbers[] = parseInt(s); numbers will contain { 1, 300, 44 }

    - #### parseInt

          public static int[] parseInt(String[] what,
                       int missing)

      Make an array of int elements from an array of String objects. If the String can't be parsed as a number, its entry in the array will be set to the value of the "missing" parameter. String s[] = { "1", "300", "apple", "44" }; int numbers[] = parseInt(s, 9999); numbers will contain { 1, 300, 9999, 44 }

    - #### nf

          public static String nf(int num,
                  int digits)

      ( begin auto-generated from nf.xml ) Utility function for formatting numbers into strings. There are two versions, one for formatting floats and one for formatting ints. The values for the digits, left, and right parameters should always be positive integers.
      As shown in the above example, nf() is used to add zeros to the left and/or right of a number. This is typically for aligning a list of numbers. To remove digits from a floating-point number, use the int(), ceil(), floor(), or round() functions. ( end auto-generated )
      Parameters:
        `num` - the number(s) to format
        `digits` - number of digits to pad with zero

          public static String[] nfc(int[] num)

      ( begin auto-generated from nfc.xml ) Utility function for formatting numbers into strings and placing appropriate commas to mark units of 1000. There are two versions, one for formatting ints and one for formatting an array of ints. The value for the digits parameter should always be a positive integer.
      For a non-US locale, this will insert periods instead of commas, or whatever is apprioriate for that region. ( end auto-generated )
      Parameters:
        `num` - the number(s) to format
      See Also:
        `nf(float, int, int)`, `nfp(float, int, int)`, `nfc(float, int)`

    - #### nfc

          public static String nfc(int num)

      nfc() or "number format with commas". This is an unfortunate misnomer because in locales where a comma is not the separator for numbers, it won't actually be outputting a comma, it'll use whatever makes sense for the locale.

    - #### nfs

          public static String nfs(int num,
                   int digits)

      ( begin auto-generated from nfs.xml ) Utility function for formatting numbers into strings. Similar to nf() but leaves a blank space in front of positive numbers so they align with negative numbers in spite of the minus symbol. There are two versions, one for formatting floats and one for formatting ints. The values for the digits, left, and right parameters should always be positive integers. ( end auto-generated )
      Parameters:
        `num` - the number(s) to format
        `digits` - number of digits to pad with zeroes

    - #### hex

          public static final String hex(byte value)

      ( begin auto-generated from hex.xml ) Converts a byte, char, int, or color to a String containing the equivalent hexadecimal notation. For example color(0, 102, 153) will convert to the String "FF006699". This function can help make your geeky debugging sessions much happier.
      Note that the maximum number of digits is 8, because an int value can only represent up to 32 bits. Specifying more than eight digits will simply shorten the string to eight anyway. ( end auto-generated )
      Parameters:
        `value` - the value to convert
      See Also:

      Returns a String that contains the binary value of a byte. The returned value will always have 8 digits.

    - #### binary

          public static final String binary(char value)

      Returns a String that contains the binary value of a char. The returned value will always have 16 digits because chars are two bytes long.

    - #### binary

          public static final String binary(int value)

      Returns a String that contains the binary value of an int. The length depends on the size of the number itself. If you want a specific number of digits use binary(int what, int digits) to specify how many.

    - #### binary

          public static final String binary(int value,
                      int digits)

      ( begin auto-generated from binary.xml ) Converts a byte, char, int, or color to a String containing the equivalent binary notation. For example color(0, 102, 153, 255) will convert to the String "11111111000000000110011010011001". This function can help make your geeky debugging sessions much happier.

    - #### main

          public static void main(String[] args)

      main() method for running this class from the command line.

      The options shown here are not yet finalized and will be changing over the next several releases.

      The simplest way to turn and applet into an application is to add the following code to your program:

          static public void main(String args[]) {
             PApplet.main("YourSketchName", args);
           }

      This will properly launch your applet from a double-clickable .jar or from the command line.

           Parameters useful for launching or also used by the PDE:

           --location=x,y        upper-lefthand corner of where the applet
                                 should appear on screen. if not used,
                                 the default is to center on the main screen.

           --full-screen         put the applet into full screen "present" mode.

           --hide-stop           use to hide the stop button in situations where
                                 you don't want to allow users to exit. also
                                 see the FAQ on information for capturing the ESC
                                 key when running in presentation mode.

           --stop-color=#xxxxxx  color of the 'stop' text used to quit an
                                 sketch when it's in present mode.

           --bgcolor=#xxxxxx     background color of the window.

           --sketch-path         location of where to save files from functions
                                 like saveStrings() or saveFrame(). defaults to
                                 the folder that the java application was
                                 launched from, which means if this isn't set by
                                 the pde, everything goes into the same folder
                                 as processing.exe.

           --display=n           set what display should be used by this sketch.
                                 displays are numbered starting from 0.

           Parameters used by Processing when running via the PDE

           --external            set when the applet is being used by the PDE

           --editor-location=x,y position of the upper-lefthand corner of the
                                 editor window, for placement of applet window

    - #### main

          public static void main(String mainClass)

      Convenience method so that PApplet.main("YourSketch") launches a sketch, rather than having to wrap it into a String array.
      Parameters:
        `mainClass` - name of the class to load (with package if any)

    - #### main

          public static void main(String mainClass,
                  String[] passedArgs)

      Convenience method so that PApplet.main("YourSketch", args) launches a sketch, rather than having to wrap it into a String array, and appending the 'args' array when not null.
      Parameters:
        `mainClass` - name of the class to load (with package if any)
        `args` - command line arguments to pass to the sketch

    - #### runSketch

          public static void runSketch(String[] args,
                       PApplet constructedApplet)

    - #### beginRecord

          public PGraphics beginRecord(String renderer,
                              String filename)

      ( begin auto-generated from beginRecord.xml ) Opens a new file and all subsequent drawing functions are echoed to this file as well as the display window. The beginRecord() function requires two parameters, the first is the renderer and the second is the file name. This function is always used with endRecord() to stop the recording process and close the file.
      Note that beginRecord() will only pick up any settings that happen after it has been called. For instance, if you call textFont() before beginRecord(), then that font will not be set for the file that you're recording to. ( end auto-generated )
      Parameters:
        `renderer` - for example, PDF
        `filename` - filename for output
      See Also:
        `endRecord()`

    - #### beginRecord

          public void beginRecord(PGraphics recorder)

    - #### endRecord

          public void endRecord()

      ( begin auto-generated from endRecord.xml ) Stops the recording process started by beginRecord() and closes the file. ( end auto-generated )
      See Also:
        `beginRecord(String, String)`

    - #### beginRaw

          public PGraphics beginRaw(String renderer,
                           String filename)

      ( begin auto-generated from beginRaw.xml ) To create vectors from 3D data, use the beginRaw() and endRaw() commands. These commands will grab the shape data just before it is rendered to the screen. At this stage, your entire scene is nothing but a long list of individual lines and triangles. This means that a shape created with sphere() function will be made up of hundreds of triangles, rather than a single object. Or that a multi-segment line shape (such as a curve) will be rendered as individual segments.
      When using beginRaw() and endRaw(), it's possible to write to either a 2D or 3D renderer. For instance, beginRaw() with the PDF library will write the geometry as flattened triangles and lines, even if recording from the P3D renderer.
      If you want a background to show up in your files, use rect(0, 0, width, height) after setting the fill() to the background color. Otherwise the background will not be rendered to the file because the background is not shape.
      Using hint(ENABLE_DEPTH_SORT) can improve the appearance of 3D geometry drawn to 2D file formats. See the hint() reference for more details.
      See examples in the reference for the PDF and DXF libraries for more information. ( end auto-generated )
      Parameters:
        `renderer` - for example, PDF or DXF
        `filename` - filename for output
      See Also:
        `endRaw()`, `hint(int)`

    - #### beginRaw

          public void beginRaw(PGraphics rawGraphics)

      Parameters:
        `rawGraphics` - ???

    - #### endRaw

          public void endRaw()

      ( begin auto-generated from endRaw.xml ) Complement to beginRaw(); they must always be used together. See the beginRaw() reference for details. ( end auto-generated )
      See Also:
        `beginRaw(String, String)`

    - #### loadPixels

          public void loadPixels()

      ( begin auto-generated from loadPixels.xml ) Loads the pixel data for the display window into the pixels[] array. This function must always be called before reading from or writing to pixels[].
      renderers may or may not seem to require loadPixels() or updatePixels(). However, the rule is that any time you want to manipulate the pixels[] array, you must first call loadPixels(), and after changes have been made, call updatePixels(). Even if the renderer may not seem to use this function in the current Processing release, this will always be subject to change. ( end auto-generated )

      ### Advanced

      Override the g.pixels[] function to set the pixels[] array that's part of the PApplet object. Allows the use of pixels[] in the code, rather than g.pixels[].
      See Also:
        `pixels`, `updatePixels()`

    - #### updatePixels

          public void updatePixels()

      ( begin auto-generated from updatePixels.xml ) Updates the display window with the data in the pixels[] array. Use in conjunction with loadPixels(). If you're only reading pixels from the array, there's no need to call updatePixels() unless there are changes.
      renderers may or may not seem to require loadPixels() or updatePixels(). However, the rule is that any time you want to manipulate the pixels[] array, you must first call loadPixels(), and after changes have been made, call updatePixels(). Even if the renderer may not seem to use this function in the current Processing release, this will always be subject to change.
      Currently, none of the renderers use the additional parameters to updatePixels(), however this may be implemented in the future. ( end auto-generated )
      See Also:
        `loadPixels()`, `pixels`

    - #### updatePixels

          public void updatePixels(int x1,
                          int y1,
                          int x2,
                          int y2)

      Parameters:
        `x1` - x-coordinate of the upper-left corner
        `y1` - y-coordinate of the upper-left corner
        `x2` - width of the region
        `y2` - height of the region

    - #### setCache

          public void setCache(PImage image,
                      Object storage)

      Store data of some kind for the renderer that requires extra metadata of some kind. Usually this is a renderer-specific representation of the image data, for instance a BufferedImage with tint() settings applied for PGraphicsJava2D, or resized image data and OpenGL texture indices for PGraphicsOpenGL.
      Parameters:
        `renderer` - The PGraphics renderer associated to the image
        `storage` - The metadata required by the renderer

    - #### getCache

          public Object getCache(PImage image)

      Get cache storage data for the specified renderer. Because each renderer will cache data in different formats, it's necessary to store cache data keyed by the renderer object. Otherwise, attempting to draw the same image to both a PGraphicsJava2D and a PGraphicsOpenGL will cause errors.
      Parameters:
        `renderer` - The PGraphics renderer associated to the image
      Returns:
        metadata stored for the specified renderer

    - #### removeCache

          public void removeCache(PImage image)

      Remove information associated with this renderer from the cache, if any.
      Parameters:
        `renderer` - The PGraphics renderer whose cache data should be removed

    - #### beginPGL

          public PGL beginPGL()

    - #### endPGL

          public void endPGL()

    - #### flush

          public void flush()

    - #### hint

          public void hint(int which)

    - #### beginShape

          public void beginShape()

      Start a new shape of type POLYGON

    - #### beginShape

          public void beginShape(int kind)

      ( begin auto-generated from beginShape.xml ) Using the beginShape() and endShape() functions allow creating more complex forms. beginShape() begins recording vertices for a shape and endShape() stops recording. The value of the MODE parameter tells it which types of shapes to create from the provided vertices. With no mode specified, the shape can be any irregular polygon. The parameters available for beginShape() are POINTS, LINES, TRIANGLES, TRIANGLE_FAN, TRIANGLE_STRIP, QUADS, and QUAD_STRIP. After calling the beginShape() function, a series of vertex() commands must follow. To stop drawing the shape, call endShape(). The vertex() function with two parameters specifies a position in 2D and the vertex() function with three parameters specifies a position in 3D. Each shape will be outlined with the current stroke color and filled with the fill color.
      Transformations such as translate(), rotate(), and scale() do not work within beginShape(). It is also not possible to use other shapes, such as ellipse() or rect() within beginShape().
      The P3D renderer settings allow stroke() and fill() settings to be altered per-vertex, however the default P2D renderer does not. Settings such as strokeWeight(), strokeCap(), and strokeJoin() cannot be changed while inside a beginShape()/endShape() block with any renderer. ( end auto-generated )
      Parameters:
        `kind` - Either POINTS, LINES, TRIANGLES, TRIANGLE_FAN, TRIANGLE_STRIP, QUADS, or QUAD_STRIP
      See Also:
        `PShape`, `PGraphics.endShape()`, `PGraphics.vertex(float, float, float, float, float)`, `PGraphics.curveVertex(float, float, float)`, `PGraphics.bezierVertex(float, float, float, float, float, float, float, float, float)`

    - #### edge

          public void edge(boolean edge)

      Sets whether the upcoming vertex is part of an edge. Equivalent to glEdgeFlag(), for people familiar with OpenGL.

    - #### normal

          public void normal(float nx,
                    float ny,
                    float nz)

      ( begin auto-generated from normal.xml ) Sets the current normal vector. This is for drawing three dimensional shapes and surfaces and specifies a vector perpendicular to the surface of the shape which determines how lighting affects it. Processing attempts to automatically assign normals to shapes, but since that's imperfect, this is a better option when you want more control. This function is identical to glNormal3f() in OpenGL. ( end auto-generated )
      Parameters:
        `nx` - x direction
        `ny` - y direction
        `nz` - z direction
      See Also:
        `PGraphics.beginShape(int)`, `PGraphics.endShape(int)`, `PGraphics.lights()`

    - #### textureMode

          public void textureMode(int mode)

      ( begin auto-generated from textureMode.xml ) Sets the coordinate space for texture mapping. There are two options, IMAGE, which refers to the actual coordinates of the image, and NORMAL, which refers to a normalized space of values ranging from 0 to 1. The default mode is IMAGE. In IMAGE, if an image is 100 x 200 pixels, mapping the image onto the entire size of a quad would require the points (0,0) (0,100) (100,200) (0,200). The same mapping in NORMAL_SPACE is (0,0) (0,1) (1,1) (0,1). ( end auto-generated )
      Parameters:
        `mode` - either IMAGE or NORMAL
      See Also:
        `PGraphics.texture(PImage)`, `PGraphics.textureWrap(int)`

    - #### textureWrap

          public void textureWrap(int wrap)

      ( begin auto-generated from textureWrap.xml ) Description to come... ( end auto-generated from textureWrap.xml )
      Parameters:
        `wrap` - Either CLAMP (default) or REPEAT
      See Also:
        `PGraphics.texture(PImage)`, `PGraphics.textureMode(int)`

    - #### texture

          public void texture(PImage image)

      ( begin auto-generated from texture.xml ) Sets a texture to be applied to vertex points. The texture() function must be called between beginShape() and endShape() and before any calls to vertex().
      When textures are in use, the fill color is ignored. Instead, use tint() to specify the color of the texture as it is applied to the shape. ( end auto-generated )
      Parameters:
        `image` - reference to a PImage object
      See Also:
        `PGraphics.textureMode(int)`, `PGraphics.textureWrap(int)`, `PGraphics.beginShape(int)`, `PGraphics.endShape(int)`, `PGraphics.vertex(float, float, float, float, float)`

    - #### noTexture

          public void noTexture()

    - #### vertex

          public void vertex(float x,
                    float y)

    - #### vertex

          public void vertex(float x,
                    float y,
                    float z)

    - #### vertex

          public void vertex(float[] v)

      Used by renderer subclasses or PShape to efficiently pass in already formatted vertex information.
      Parameters:
        `v` - vertex parameters, as a float array of length VERTEX_FIELD_COUNT

    - #### vertex

          public void vertex(float x,
                    float y,
                    float u,
                    float v)

    - #### vertex

          public void vertex(float x,
                    float y,
                    float z,
                    float u,
                    float v)

      ( begin auto-generated from vertex.xml ) All shapes are constructed by connecting a series of vertices. vertex() is used to specify the vertex coordinates for points, lines, triangles, quads, and polygons and is used exclusively within the beginShape() and endShape() function.
      Drawing a vertex in 3D using the z parameter requires the P3D parameter in combination with size as shown in the above example.
      This function is also used to map a texture onto the geometry. The texture() function declares the texture to apply to the geometry and the u and v coordinates set define the mapping of this texture to the form. By default, the coordinates used for u and v are specified in relation to the image's size in pixels, but this relation can be changed with textureMode(). ( end auto-generated )
      Parameters:
        `x` - x-coordinate of the vertex
        `y` - y-coordinate of the vertex
        `z` - z-coordinate of the vertex
        `u` - horizontal coordinate for the texture mapping
        `v` - vertical coordinate for the texture mapping
      See Also:

    - #### endShape

          public void endShape(int mode)

      ( begin auto-generated from endShape.xml ) The endShape() function is the companion to beginShape() and may only be called after beginShape(). When endshape() is called, all of image data defined since the previous call to beginShape() is written into the image buffer. The constant CLOSE as the value for the MODE parameter to close the shape (to connect the beginning and the end). ( end auto-generated )
      Parameters:
        `mode` - use CLOSE to close the shape

                          float z4)

      ( begin auto-generated from bezierVertex.xml ) Specifies vertex coordinates for Bezier curves. Each call to bezierVertex() defines the position of two control points and one anchor point of a Bezier curve, adding a new segment to a line or shape. The first time bezierVertex() is used within a beginShape() call, it must be prefaced with a call to vertex() to set the first anchor point. This function must be used between beginShape() and endShape() and only when there is no MODE parameter specified to beginShape(). Using the 3D version requires rendering with P3D (see the Environment reference for more information). ( end auto-generated )
      Parameters:
        `x2` - the x-coordinate of the 1st control point
        `y2` - the y-coordinate of the 1st control point

      ( begin auto-generated from curveVertex.xml ) Specifies vertex coordinates for curves. This function may only be used between beginShape() and endShape() and only when there is no MODE parameter specified to beginShape(). The first and last points in a series of curveVertex() lines will be used to guide the beginning and end of a the curve. A minimum of four points is required to draw a tiny curve between the second and third points. Adding a fifth point with curveVertex() will draw the curve between the second, third, and fourth points. The curveVertex() function is an implementation of Catmull-Rom splines.

          public void point(float x,
                   float y)

      ( begin auto-generated from point.xml ) Draws a point, a coordinate in space at the dimension of one pixel. The first parameter is the horizontal value for the point, the second value is the vertical value for the point, and the optional third value is the depth value. Drawing this shape in 3D with the z parameter requires the P3D parameter in combination with size() as shown in the above example. ( end auto-generated )
      Parameters:
        `x` - x-coordinate of the point
        `y` - y-coordinate of the point

                  float y2)

      ( begin auto-generated from line.xml ) Draws a line (a direct path between two points) to the screen. The version of line() with four parameters draws the line in 2D. To color a line, use the stroke() function. A line cannot be filled, therefore the fill() function will not affect the color of a line. 2D lines are drawn with a width of one pixel by default, but this can be changed with the strokeWeight() function. The version with six parameters allows the line to be placed anywhere within XYZ space. Drawing this shape in 3D with the z parameter requires the P3D parameter in combination with size() as shown in the above example. ( end auto-generated )
      Parameters:
        `x1` - x-coordinate of the first point
        `y1` - y-coordinate of the first point

    - #### rectMode

          public void rectMode(int mode)

      ( begin auto-generated from rectMode.xml ) Modifies the location from which rectangles draw. The default mode is rectMode(CORNER), which specifies the location to be the upper left corner of the shape and uses the third and fourth parameters of rect() to specify the width and height. The syntax rectMode(CORNERS) uses the first and second parameters of rect() to set the location of one corner and uses the third and fourth parameters to set the opposite corner. The syntax rectMode(CENTER) draws the image from its center point and uses the third and forth parameters of rect() to specify the image's width and height. The syntax rectMode(RADIUS) draws the image from its center point and uses the third and forth parameters of rect() to specify half of the image's width and height. The parameter must be written in ALL CAPS because Processing is a case sensitive language. Note: In version 125, the mode named CENTER_RADIUS was shortened to RADIUS. ( end auto-generated )
      Parameters:
        `mode` - either CORNER, CORNERS, CENTER, or RADIUS

    - #### ellipseMode

          public void ellipseMode(int mode)

      ( begin auto-generated from ellipseMode.xml ) The origin of the ellipse is modified by the ellipseMode() function. The default configuration is ellipseMode(CENTER), which specifies the location of the ellipse as the center of the shape. The RADIUS mode is the same, but the width and height parameters to ellipse() specify the radius of the ellipse, rather than the diameter. The CORNER mode draws the shape from the upper-left corner of its bounding box. The CORNERS mode uses the four parameters to ellipse() to set two opposing corners of the ellipse's bounding box. The parameter must be written in ALL CAPS because Processing is a case-sensitive language. ( end auto-generated )
      Parameters:

    - #### sphereDetail

          public void sphereDetail(int res)

      ( begin auto-generated from sphereDetail.xml ) Controls the detail used to render a sphere by adjusting the number of vertices of the sphere mesh. The default resolution is 30, which creates a fairly detailed sphere definition with vertices every 360/30 = 12 degrees. If you're going to render a great number of spheres per frame, it is advised to reduce the level of detail using this function. The setting stays active until sphereDetail() is called again with a new parameter and so should not be called prior to every sphere() statement, unless you wish to render spheres with different settings, e.g. using less detail for smaller spheres or ones further away from the camera. To control the detail of the horizontal and vertical resolution independently, use the version of the functions with two parameters. ( end auto-generated )

      ### Advanced

      Implementation notes:

      cache all the points of the sphere in a static array top and bottom are just a bunch of triangles that land in the center point

      sphere is a series of concentric circles who radii vary along the shape, based on, er.. cos or something

           [toxi 031031] new sphere code. removed all multiplies with
           radius, as scale() will take care of that anyway

           [toxi 031223] updated sphere code (removed modulos)
           and introduced sphereAt(x,y,z,r)
           to avoid additional translate()'s on the user/sketch side

           [davbol 080801] now using separate sphereDetailU/V

      Code submitted by Dave Bollinger (davol) for release 0136.
      Parameters:

    - #### bezierDetail

          public void bezierDetail(int detail)

      ( begin auto-generated from bezierDetail.xml ) Sets the resolution at which Beziers display. The default value is 20. This function is only useful when using the P3D renderer as the default P2D renderer does not use this information. ( end auto-generated )

        `PGraphics.curve(float, float, float, float, float, float, float, float, float, float, float, float)`, `PGraphics.curveVertex(float, float, float)`, `PGraphics.curveTightness(float)`

    - #### bezier

                    float y1,
                    float x2,

                    float x4,
                    float y4)

    - #### bezier

          public void bezier(float x1,
                    float y1,
                    float z1,
                    float x2,

                    float y4,
                    float z4)

      ( begin auto-generated from bezier.xml ) Draws a Bezier curve on the screen. These curves are defined by a series of anchor and control points. The first two parameters specify the first anchor point and the last two parameters specify the other anchor point. The middle parameters specify the control points which define the shape of the curve. Bezier curves were developed by French engineer Pierre Bezier. Using the 3D version requires rendering with P3D (see the Environment reference for more information). ( end auto-generated )

      ### Advanced

      Draw a cubic bezier curve. The first and last points are the on-curve points. The middle two are the 'control' points, or 'handles' in an application like Illustrator.

      Identical to typing:

          beginShape();
           vertex(x1, y1);
           bezierVertex(x2, y2, x3, y3, x4, y4);
           endShape();

      In Postscript-speak, this would be:

          moveto(x1, y1);
           curveto(x2, y2, x3, y3, x4, y4);

      If you were to try and continue that curve like so:

          curveto(x5, y5, x6, y6, x7, y7);

      This would be done in processing by adding these statements:

          bezierVertex(x5, y5, x6, y6, x7, y7)

      To draw a quadratic (instead of cubic) curve, use the control point twice by doubling it:

          bezier(x1, y1, cx, cy, cx, cy, x2, y2);

      Parameters:
        `x1` - coordinates for the first anchor point
        `y1` - coordinates for the first anchor point
        `z1` - coordinates for the first anchor point
        `x2` - coordinates for the first control point
        `y2` - coordinates for the first control point
        `z2` - coordinates for the first control point
        `x3` - coordinates for the second control point
        `y3` - coordinates for the second control point
        `z3` - coordinates for the second control point
        `x4` - coordinates for the second anchor point
        `y4` - coordinates for the second anchor point
        `z4` - coordinates for the second anchor point

    - #### curvePoint

          public float curvePoint(float a,
                         float b,
                         float c,
                         float d,
                         float t)

      ( begin auto-generated from curvePoint.xml ) Evalutes the curve at point t for points a, b, c, d. The parameter t varies between 0 and 1, a and d are points on the curve, and b and c are the control points. This can be done once with the x coordinates and a second time with the y coordinates to get the location of a curve at t. ( end auto-generated )
      Parameters:
        `a` - coordinate of first point on the curve
        `b` - coordinate of second point on the curve
        `c` - coordinate of third point on the curve
        `d` - coordinate of fourth point on the curve
        `t` - value between 0 and 1

                           float d,
                           float t)

      ( begin auto-generated from curveTangent.xml ) Calculates the tangent of a point on a curve. There's a good definition of tangent on Wikipedia. ( end auto-generated )

      ### Advanced

      Code thanks to Dave Bollinger (Bug #715)
      Parameters:
        `a` - coordinate of first point on the curve
        `b` - coordinate of first control point
        `c` - coordinate of second control point
        `d` - coordinate of second point on the curve

    - #### curveDetail

          public void curveDetail(int detail)

      ( begin auto-generated from curveDetail.xml ) Sets the resolution at which curves display. The default value is 20. This function is only useful when using the P3D renderer as the default P2D renderer does not use this information. ( end auto-generated )
      Parameters:
        `detail` - resolution of the curves
      See Also:
        `PGraphics.curve(float, float, float, float, float, float, float, float, float, float, float, float)`, `PGraphics.curveVertex(float, float)`, `PGraphics.curveTightness(float)`

    - #### curveTightness

          public void curveTightness(float tightness)

      ( begin auto-generated from curveTightness.xml ) Modifies the quality of forms created with curve() and curveVertex(). The parameter squishy determines how the curve fits to the vertex points. The value 0.0 is the default value for squishy (this value defines the curves to be Catmull-Rom splines) and the value 1.0 connects all the points with straight lines. Values within the range -5.0 and 5.0 will deform the curves but will leave them recognizable and as values increase in magnitude, they will continue to deform. ( end auto-generated )
      Parameters:
        `tightness` - amount of deformation from the original vertices
      See Also:
        `PGraphics.curve(float, float, float, float, float, float, float, float, float, float, float, float)`, `PGraphics.curveVertex(float, float)`

    - #### curve

          public void curve(float x1,
                   float y1,
                   float x2,
                   float y2,
                   float x3,
                   float y3,
                   float x4,
                   float y4)

      ( begin auto-generated from curve.xml ) Draws a curved line on the screen. The first and second parameters specify the beginning control point and the last two parameters specify the ending control point. The middle parameters specify the start and stop of the curve. Longer curves can be created by putting a series of curve() functions together or using curveVertex(). An additional function called curveTightness() provides control for the visual quality of the curve. The curve() function is an implementation of Catmull-Rom splines. Using the 3D version requires rendering with P3D (see the Environment reference for more information). ( end auto-generated )

      ### Advanced

      As of revision 0070, this function no longer doubles the first and last points. The curves are a bit more boring, but it's more mathematically correct, and properly mirrored in curvePoint().

      Identical to typing out:

           beginShape();
           curveVertex(x1, y1);
           curveVertex(x2, y2);
           curveVertex(x3, y3);
           curveVertex(x4, y4);
           endShape();

      Parameters:
        `x1` - coordinates for the beginning control point
        `y1` - coordinates for the beginning control point
        `x2` - coordinates for the first point
        `y2` - coordinates for the first point
        `x3` - coordinates for the second point
        `y3` - coordinates for the second point
        `x4` - coordinates for the ending control point
        `y4` - coordinates for the ending control point
      See Also:
        `PGraphics.curveVertex(float, float)`, `PGraphics.curveTightness(float)`, `PGraphics.bezier(float, float, float, float, float, float, float, float, float, float, float, float)`

    - #### curve

          public void curve(float x1,
                   float y1,
                   float z1,
                   float x2,
                   float y2,
                   float z2,
                   float x3,
                   float y3,
                   float z3,
                   float x4,
                   float y4,
                   float z4)

      Parameters:
        `z1` - coordinates for the beginning control point
        `z2` - coordinates for the first point
        `z3` - coordinates for the second point
        `z4` - coordinates for the ending control point

    - #### smooth

          public void smooth()

      ( begin auto-generated from smooth.xml ) Draws all geometry with smooth (anti-aliased) edges. This will sometimes slow down the frame rate of the application, but will enhance the visual refinement. Note that smooth() will also improve image quality of resized images, and noSmooth() will disable image (and font) smoothing altogether. ( end auto-generated )
      See Also:
        `PGraphics.noSmooth()`, `PGraphics.hint(int)`, `size(int, int, String)`

    - #### smooth

          public void smooth(int level)

      Parameters:
        `level` - either 2, 4, or 8

    - #### noSmooth

          public void noSmooth()

      ( begin auto-generated from noSmooth.xml ) Draws all geometry with jagged (aliased) edges. ( end auto-generated )
      See Also:
        `PGraphics.smooth()`

    - #### imageMode

          public void imageMode(int mode)

      ( begin auto-generated from imageMode.xml ) Modifies the location from which images draw. The default mode is imageMode(CORNER), which specifies the location to be the upper left corner and uses the fourth and fifth parameters of image() to set the image's width and height. The syntax imageMode(CORNERS) uses the second and third parameters of image() to set the location of one corner of the image and uses the fourth and fifth parameters to set the opposite corner. Use imageMode(CENTER) to draw images centered at the given x and y position.
      The parameter to imageMode() must be written in ALL CAPS because Processing is a case-sensitive language. ( end auto-generated )
      Parameters:
        `mode` - either CORNER, CORNERS, or CENTER
      See Also:
        `loadImage(String, String)`, `PImage`, `PGraphics.image(PImage, float, float, float, float)`, `PGraphics.background(float, float, float, float)`

    - #### image

          public void image(PImage img,
                   float a,
                   float b)

      ( begin auto-generated from image.xml ) Displays images to the screen. The images must be in the sketch's "data" directory to load correctly. Select "Add file..." from the "Sketch" menu to add the image. Processing currently works with GIF, JPEG, and Targa images. The img parameter specifies the image to display and the x and y parameters define the location of the image from its upper-left corner. The image is displayed at its original size unless the width and height parameters specify a different size.
      The imageMode() function changes the way the parameters work. For example, a call to imageMode(CORNERS) will change the width and height parameters to define the x and y values of the opposite corner of the image.
      The color of an image may be modified with the tint() function. This function will maintain transparency for GIF and PNG images. ( end auto-generated )

      ### Advanced

      Starting with release 0124, when using the default (JAVA2D) renderer, smooth() will also improve image quality of resized images.
      Parameters:
        `img` - the image to display
        `a` - x-coordinate of the image
        `b` - y-coordinate of the image
      See Also:
        `loadImage(String, String)`, `PImage`, `PGraphics.imageMode(int)`, `PGraphics.tint(float)`, `PGraphics.background(float, float, float, float)`, `PGraphics.alpha(int)`

    - #### image

          public void image(PImage img,
                   float a,
                   float b,
                   float c,
                   float d)

      Parameters:
        `c` - width to display the image
        `d` - height to display the image

    - #### image

          public void image(PImage img,
                   float a,
                   float b,
                   float c,
                   float d,
                   int u1,
                   int v1,
                   int u2,
                   int v2)

      Draw an image(), also specifying u/v coordinates. In this method, the u, v coordinates are always based on image space location, regardless of the current textureMode().

    - #### shapeMode

          public void shapeMode(int mode)

      ( begin auto-generated from shapeMode.xml ) Modifies the location from which shapes draw. The default mode is shapeMode(CORNER), which specifies the location to be the upper left corner of the shape and uses the third and fourth parameters of shape() to specify the width and height. The syntax shapeMode(CORNERS) uses the first and second parameters of shape() to set the location of one corner and uses the third and fourth parameters to set the opposite corner. The syntax shapeMode(CENTER) draws the shape from its center point and uses the third and forth parameters of shape() to specify the width and height. The parameter must be written in "ALL CAPS" because Processing is a case sensitive language. ( end auto-generated )
      Parameters:
        `mode` - either CORNER, CORNERS, CENTER
      See Also:
        `PShape`, `PGraphics.shape(PShape)`, `PGraphics.rectMode(int)`

    - #### shape

          public void shape(PShape shape)

    - #### shape

          public void shape(PShape shape,
                   float x,
                   float y)

      ( begin auto-generated from shape.xml ) Displays shapes to the screen. The shapes must be in the sketch's "data" directory to load correctly. Select "Add file..." from the "Sketch" menu to add the shape. Processing currently works with SVG shapes only. The sh parameter specifies the shape to display and the x and y parameters define the location of the shape from its upper-left corner. The shape is displayed at its original size unless the width and height parameters specify a different size. The shapeMode() function changes the way the parameters work. A call to shapeMode(CORNERS), for example, will change the width and height parameters to define the x and y values of the opposite corner of the shape.
      Note complex shapes may draw awkwardly with P3D. This renderer does not yet support shapes that have holes or complicated breaks. ( end auto-generated )
      Parameters:
        `shape` - the shape to display
        `x` - x-coordinate of the shape
        `y` - y-coordinate of the shape
      See Also:
        `PShape`, `loadShape(String)`, `Convenience method to draw at a particular location.`

    - #### shape

          public void shape(PShape shape,
                   float a,
                   float b,
                   float c,
                   float d)

      Parameters:
        `a` - x-coordinate of the shape
        `b` - y-coordinate of the shape
        `c` - width to display the shape
        `d` - height to display the shape

    - #### textAlign

          public void textAlign(int alignX)

    - #### textAlign

          public void textAlign(int alignX,
                       int alignY)

      ( begin auto-generated from textAlign.xml ) Sets the current alignment for drawing text. The parameters LEFT, CENTER, and RIGHT set the display characteristics of the letters in relation to the values for the x and y parameters of the text() function.
      In Processing 0125 and later, an optional second parameter can be used to vertically align the text. BASELINE is the default, and the vertical alignment will be reset to BASELINE if the second parameter is not used. The TOP and CENTER parameters are straightforward. The BOTTOM parameter offsets the line based on the current textDescent(). For multiple lines, the final line will be aligned to the bottom, with the previous lines appearing above it.
      When using text() with width and height parameters, BASELINE is ignored, and treated as TOP. (Otherwise, text would by default draw outside the box, since BASELINE is the default setting. BASELINE is not a useful drawing mode for text drawn in a rectangle.)
      The vertical alignment is based on the value of textAscent(), which many fonts do not specify correctly. It may be necessary to use a hack and offset by a few pixels by hand so that the offset looks correct. To do this as less of a hack, use some percentage of textAscent() or textDescent() so that the hack works even if you change the size of the font. ( end auto-generated )
      Parameters:
        `alignX` - horizontal alignment, either LEFT, CENTER, or RIGHT
        `alignY` - vertical alignment, either TOP, BOTTOM, CENTER, or BASELINE
      See Also:
        `loadFont(String)`, `PFont`, `PGraphics.text(String, float, float)`

    - #### textAscent

          public float textAscent()

      ( begin auto-generated from textAscent.xml ) Returns ascent of the current font at its current size. This information is useful for determining the height of the font above the baseline. For example, adding the textAscent() and textDescent() values will give you the total height of the line. ( end auto-generated )
      See Also:
        `PGraphics.textDescent()`

    - #### textDescent

          public float textDescent()

      ( begin auto-generated from textDescent.xml ) Returns descent of the current font at its current size. This information is useful for determining the height of the font below the baseline. For example, adding the textAscent() and textDescent() values will give you the total height of the line. ( end auto-generated )
      See Also:
        `PGraphics.textAscent()`

    - #### textFont

          public void textFont(PFont which)

      ( begin auto-generated from textFont.xml ) Sets the current font that will be drawn with the text() function. Fonts must be loaded with loadFont() before it can be used. This font will be used in all subsequent calls to the text() function. If no size parameter is input, the font will appear at its original size (the size it was created at with the "Create Font..." tool) until it is changed with textSize().
      Because fonts are usually bitmaped, you should create fonts at the sizes that will be used most commonly. Using textFont() without the size parameter will result in the cleanest-looking text.
      With the default (JAVA2D) and PDF renderers, it's also possible to enable the use of native fonts via the command hint(ENABLE_NATIVE_FONTS). This will produce vector text in JAVA2D sketches and PDF output in cases where the vector data is available: when the font is still installed, or the font is created via the createFont() function (rather than the Create Font tool). ( end auto-generated )
      Parameters:
        `which` - any variable of the type PFont
      See Also:
        `createFont(String, float, boolean)`, `loadFont(String)`, `PFont`, `PGraphics.text(String, float, float)`

    - #### textFont

          public void textFont(PFont which,
                      float size)

      Parameters:
        `size` - the size of the letters in units of pixels

    - #### textLeading

          public void textLeading(float leading)

      ( begin auto-generated from textLeading.xml ) Sets the spacing between lines of text in units of pixels. This setting will be used in all subsequent calls to the text() function. ( end auto-generated )
      Parameters:
        `leading` - the size in pixels for spacing between lines

    - #### textMode

          public void textMode(int mode)

      ( begin auto-generated from textMode.xml ) Sets the way text draws to the screen. In the default configuration, the MODEL mode, it's possible to rotate, scale, and place letters in two and three dimensional space.
      The SHAPE mode draws text using the the glyph outlines of individual characters rather than as textures. This mode is only supported with the PDF and P3D renderer settings. With the PDF renderer, you must call textMode(SHAPE) before any other drawing occurs. If the outlines are not available, then textMode(SHAPE) will be ignored and textMode(MODEL) will be used instead.
      The textMode(SHAPE) option in P3D can be combined with beginRaw() to write vector-accurate text to 2D and 3D output files, for instance DXF or PDF. The SHAPE mode is not currently optimized for P3D, so if recording shape data, use textMode(MODEL) until you're ready to capture the geometry with beginRaw(). ( end auto-generated )
      Parameters:
        `mode` - either MODEL or SHAPE

                  float x,
                  float y)

      ( begin auto-generated from text.xml ) Draws text to the screen. Displays the information specified in the data or stringdata parameters on the screen in the position specified by the x and y parameters and the optional z parameter. A default font will be used unless a font is set with the textFont() function. Change the color of the text with the fill() function. The text displays in relation to the textAlign() function, which gives the option to draw to the left, right, and center of the coordinates.
      The x2 and y2 parameters define a rectangular area to display within and may only be used with string data. For text drawn inside a rectangle, the coordinates are interpreted based on the current rectMode() setting. ( end auto-generated )

                  float x,
                  float y)

      ### Advanced

      Method to draw text from an array of chars. This method will usually be more efficient than drawing from a String object, because the String will not be converted to a char array before drawing.
      Parameters:
        `chars` - the alphanumberic symbols to be displayed
        `start` - array index at which to start writing characters
        `stop` - array index at which to stop writing characters

    - #### text

          public void text(String str,
                  float x,
                  float y,

                  float x1,
                  float y1,
                  float x2,
                  float y2)

      ### Advanced

      Draw text in a box that is constrained to a particular size. The current rectMode() determines what the coordinates mean (whether x1/y1/x2/y2 or x/y/w/h).

      Note that the x,y coords of the start of the box will align with the *ascent* of the text, not the baseline, as is the case for the other text() functions.

      Newlines that are \n (Unix newline or linefeed char, ascii 10) are honored, and \r (carriage return, Windows and Mac OS) are ignored.
      Parameters:
        `x1` - by default, the x-coordinate of text, see rectMode() for more info
        `y1` - by default, the x-coordinate of text, see rectMode() for more info
        `x2` - by default, the width of the text box, see rectMode() for more info
        `y2` - by default, the height of the text box, see rectMode() for more info

    - #### text

          public void text(int num,
                  float x,
                  float y)

    - #### text

          public void text(int num,
                  float x,
                  float y,
                  float z)

    - #### text

          public void text(float num,
                  float x,
                  float y)

      This does a basic number formatting, to avoid the generally ugly appearance of printing floats. Users who want more control should use their own nf() cmmand, or if they want the long, ugly version of float, use String.valueOf() to convert the float to a String first.
      Parameters:
        `num` - the numeric value to be displayed

    - #### text

          public void text(float num,
                  float x,
                  float y,
                  float z)

    - #### pushMatrix

          public void pushMatrix()

      ( begin auto-generated from pushMatrix.xml ) Pushes the current transformation matrix onto the matrix stack. Understanding pushMatrix() and popMatrix() requires understanding the concept of a matrix stack. The pushMatrix() function saves the current coordinate system to the stack and popMatrix() restores the prior coordinate system. pushMatrix() and popMatrix() are used in conjuction with the other transformation functions and may be embedded to control the scope of the transformations. ( end auto-generated )
      See Also:
        `PGraphics.popMatrix()`, `PGraphics.translate(float, float, float)`, `PGraphics.rotate(float)`, `PGraphics.rotateX(float)`, `PGraphics.rotateY(float)`, `PGraphics.rotateZ(float)`

    - #### popMatrix

          public void popMatrix()

      ( begin auto-generated from popMatrix.xml ) Pops the current transformation matrix off the matrix stack. Understanding pushing and popping requires understanding the concept of a matrix stack. The pushMatrix() function saves the current coordinate system to the stack and popMatrix() restores the prior coordinate system. pushMatrix() and popMatrix() are used in conjuction with the other transformation functions and may be embedded to control the scope of the transformations.

    - #### translate

          public void translate(float x,
                       float y)

      ( begin auto-generated from translate.xml ) Specifies an amount to displace objects within the display window. The x parameter specifies left/right translation, the y parameter specifies up/down translation, and the z parameter specifies translations toward/away from the screen. Using this function with the z parameter requires using P3D as a parameter in combination with size as shown in the above example. Transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, calling translate(50, 0) and then translate(20, 0) is the same as translate(70, 0). If translate() is called within draw(), the transformation is reset when the loop begins again. This function can be further controlled by the pushMatrix() and popMatrix(). ( end auto-generated )
      Parameters:
        `x` - left/right translation
        `y` - up/down translation

      Parameters:
        `z` - forward/backward translation

    - #### rotate

          public void rotate(float angle)

      ( begin auto-generated from rotate.xml ) Rotates a shape the amount specified by the angle parameter. Angles should be specified in radians (values from 0 to TWO_PI) or converted to radians with the radians() function.
      Objects are always rotated around their relative position to the origin and positive numbers rotate objects in a clockwise direction. Transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, calling rotate(HALF_PI) and then rotate(HALF_PI) is the same as rotate(PI). All tranformations are reset when draw() begins again.
      Technically, rotate() multiplies the current transformation matrix by a rotation matrix. This function can be further controlled by the pushMatrix() and popMatrix(). ( end auto-generated )

Transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, calling rotateX(PI/2) and then rotateX(PI/2) is the same as rotateX(PI). If rotateX() is called within the draw(), the transformation is reset when the loop begins again. This function requires using P3D as a third parameter to size() as shown in the example above. ( end auto-generated )

Objects are always rotated around their relative position to the origin and positive numbers rotate objects in a counterclockwise direction. Transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, calling rotateY(PI/2) and then rotateY(PI/2) is the same as rotateY(PI). If rotateY() is called within the draw(), the transformation is reset when the loop begins again.

          public void rotateZ(float angle)

      ( begin auto-generated from rotateZ.xml ) Rotates a shape around the z-axis the amount specified by the angle parameter. Angles should be specified in radians (values from 0 to PI*2) or converted to radians with the radians() function. Objects are always rotated around their relative position to the origin and positive numbers rotate objects in a counterclockwise direction. Transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, calling rotateZ(PI/2) and then rotateZ(PI/2) is the same as rotateZ(PI). If rotateZ() is called within the draw(), the transformation is reset when the loop begins again.

      ( begin auto-generated from scale.xml ) Increases or decreases the size of a shape by expanding and contracting vertices. Objects always scale from their relative origin to the coordinate system. Scale values are specified as decimal percentages. For example, the function call scale(2.0) increases the dimension of a shape by 200%. Transformations apply to everything that happens after and subsequent calls to the function multiply the effect. For example, calling scale(2.0) and then scale(1.5) is the same as scale(3.0). If scale() is called within draw(), the transformation is reset when the loop begins again. Using this fuction with the z parameter requires using P3D as a parameter for size() as shown in the example above. This function can be further controlled by pushMatrix() and popMatrix(). ( end auto-generated )

    - #### scale

          public void scale(float x,
                   float y)

      ### Advanced

      Scale in X and Y. Equivalent to scale(sx, sy, 1). Not recommended for use in 3D, because the z-dimension is just scaled by 1, since there's no way to know what else to scale it by.

    - #### shearX

          public void shearX(float angle)

      ( begin auto-generated from shearX.xml ) Shears a shape around the x-axis the amount specified by the angle parameter. Angles should be specified in radians (values from 0 to PI*2) or converted to radians with the radians() function. Objects are always sheared around their relative position to the origin and positive numbers shear objects in a clockwise direction. Transformations apply to everything that happens after and subsequent calls to the function accumulates the effect. For example, calling shearX(PI/2) and then shearX(PI/2) is the same as shearX(PI). If shearX() is called within the draw(), the transformation is reset when the loop begins again.
      Technically, shearX() multiplies the current transformation matrix by a rotation matrix. This function can be further controlled by the pushMatrix() and popMatrix() functions. ( end auto-generated )

    - #### beginCamera

          public void beginCamera()

      ( begin auto-generated from beginCamera.xml ) The beginCamera() and endCamera() functions enable advanced customization of the camera space. The functions are useful if you want to more control over camera movement, however for most users, the camera() function will be sufficient.
      The camera functions will replace any transformations (such as rotate() or translate()) that occur before them in draw(), but they will not automatically replace the camera transform itself. For this reason, camera functions should be placed at the beginning of draw() (so that transformations happen afterwards), and the camera() function can be used after beginCamera() if you want to reset the camera before applying transformations.
      This function sets the matrix mode to the camera matrix so calls such as translate(), rotate(), applyMatrix() and resetMatrix() affect the camera. beginCamera() should always be used with a following endCamera() and pairs of beginCamera() and endCamera() cannot be nested. ( end auto-generated )

    - #### camera

          public void camera()

      ( begin auto-generated from camera.xml ) Sets the position of the camera through setting the eye position, the center of the scene, and which axis is facing upward. Moving the eye position and the direction it is pointing (the center of the scene) allows the images to be seen from different angles. The version without any parameters sets the camera to the default position, pointing to the center of the display window with the Y axis as up. The default values are camera(width/2.0, height/2.0, (height/2.0) / tan(PI*30.0 / 180.0), width/2.0, height/2.0, 0, 0, 1, 0). This function is similar to gluLookAt() in OpenGL, but it first clears the current camera settings. ( end auto-generated )

      ( begin auto-generated from ortho.xml ) Sets an orthographic projection and defines a parallel clipping volume. All objects with the same dimension appear the same size, regardless of whether they are near or far from the camera. The parameters to this function specify the clipping volume where left and right are the minimum and maximum x values, top and bottom are the minimum and maximum y values, and near and far are the minimum and maximum z values. If no parameters are given, the default is used: ortho(0, width, 0, height, -10, 10). ( end auto-generated )

      Parameters:
        `near` - maximum distance from the origin to the viewer
        `far` - maximum distance from the origin away from the viewer

    - #### perspective

          public void perspective()

      ( begin auto-generated from perspective.xml ) Sets a perspective projection applying foreshortening, making distant objects appear smaller than closer ones. The parameters define a viewing volume with the shape of truncated pyramid. Objects near to the front of the volume appear their actual size, while farther objects appear smaller. This projection simulates the perspective of the world more accurately than orthographic projection. The version of perspective without parameters sets the default perspective and the version with four parameters allows the programmer to set the area precisely. The default values are: perspective(PI/3.0, width/height, cameraZ/10.0, cameraZ*10.0) where cameraZ is ((height/2.0) / tan(PI*60.0/360.0)); ( end auto-generated )

                     float near,
                     float far)

      ( begin auto-generated from frustum.xml ) Sets a perspective matrix defined through the parameters. Works like glFrustum, except it wipes out the current perspective matrix rather than muliplying itself with it. ( end auto-generated )
      Parameters:
        `left` - left coordinate of the clipping plane
        `right` - right coordinate of the clipping plane
        `bottom` - bottom coordinate of the clipping plane

      ( begin auto-generated from modelX.xml ) Returns the three-dimensional X, Y, Z position in model space. This returns the X value for a given coordinate based on the current set of transformations (scale, rotate, translate, etc.) The X value can be used to place an object in space relative to the location of the original point once the transformations are no longer in use.
      In the example, the modelX(), modelY(), and modelZ() functions record the location of a box in space after being placed using a series of translate and rotate commands. After popMatrix() is called, those transformations no longer apply, but the (x, y, z) coordinate returned by the model functions is used to place another box in the same location. ( end auto-generated )
      Parameters:
        `x` - 3D x-coordinate to be mapped
        `y` - 3D y-coordinate to be mapped
        `z` - 3D z-coordinate to be mapped

                     float y,
                     float z)

      ( begin auto-generated from modelZ.xml ) Returns the three-dimensional X, Y, Z position in model space.

    - #### pushStyle

          public void pushStyle()

      ( begin auto-generated from pushStyle.xml ) The pushStyle() function saves the current style settings and popStyle() restores the prior settings. Note that these functions are always used together. They allow you to change the style settings and later return to what you had. When a new style is started with pushStyle(), it builds on the current style information. The pushStyle() and popStyle() functions can be embedded to provide more control (see the second example above for a demonstration.)
      The style information controlled by the following functions are included in the style: fill(), stroke(), tint(), strokeWeight(), strokeCap(), strokeJoin(), imageMode(), rectMode(), ellipseMode(), shapeMode(), colorMode(), textAlign(), textFont(), textMode(), textSize(), textLeading(), emissive(), specular(), shininess(), ambient() ( end auto-generated )

    - #### popStyle

          public void popStyle()

      ( begin auto-generated from popStyle.xml ) The pushStyle() function saves the current style settings and popStyle() restores the prior settings; these functions are always used together. They allow you to change the style settings and later return to what you had. When a new style is started with pushStyle(), it builds on the current style information. The pushStyle() and popStyle() functions can be embedded to provide more control (see the second example above for a demonstration.) ( end auto-generated )

    - #### strokeWeight

          public void strokeWeight(float weight)

      ( begin auto-generated from strokeWeight.xml ) Sets the width of the stroke used for lines, points, and the border around shapes. All widths are set in units of pixels.
      When drawing with P3D, series of connected lines (such as the stroke around a polygon, triangle, or ellipse) produce unattractive results when a thick stroke weight is set (see Issue 123). With P3D, the minimum and maximum values for strokeWeight() are controlled by the graphics card and the operating system's OpenGL implementation. For instance, the thickness may not go higher than 10 pixels. ( end auto-generated )
      Parameters:
        `weight` - the weight (in pixels) of the stroke

    - #### strokeCap

          public void strokeCap(int cap)

      ( begin auto-generated from strokeCap.xml ) Sets the style for rendering line endings. These ends are either squared, extended, or rounded and specified with the corresponding parameters SQUARE, PROJECT, and ROUND. The default cap is ROUND.
      This function is not available with the P3D renderer (see Issue 123). More information about the renderers can be found in the size() reference. ( end auto-generated )
      Parameters:
        `cap` - either SQUARE, PROJECT, or ROUND

    - #### noStroke

          public void noStroke()

      ( begin auto-generated from noStroke.xml ) Disables drawing the stroke (outline). If both noStroke() and noFill() are called, nothing will be drawn to the screen. ( end auto-generated )

        `PGraphics.stroke(float, float, float, float)`

    - #### stroke

          public void stroke(int rgb)

      ( begin auto-generated from stroke.xml ) Sets the color used to draw lines and borders around shapes. This color is either specified in terms of the RGB or HSB color depending on the current colorMode() (the default color space is RGB, with each value in the range from 0 to 255).
      When using hexadecimal notation to specify a color, use "#" or "0x" before the values (e.g. #CCFFAA, 0xFFCCFFAA). The # syntax uses six digits to specify a color (the way colors are specified in HTML and CSS). When using the hexadecimal notation starting with "0x", the hexadecimal value must be specified with eight characters; the first two characters define the alpha component and the remainder the red, green, and blue components.
      The value for the parameter "gray" must be less than or equal to the current maximum value as specified by colorMode(). The default maximum value is 255. ( end auto-generated )
      Parameters:
        `rgb` - color value in hexadecimal notation

      Parameters:
        `v1` - red or hue value (depending on current color mode)
        `v2` - green or saturation value (depending on current color mode)
        `v3` - blue or brightness value (depending on current color mode)

    - #### tint

          public void tint(int rgb)

      ( begin auto-generated from tint.xml ) Sets the fill value for displaying images. Images can be tinted to specified colors or made transparent by setting the alpha.
      To make an image transparent, but not change it's color, use white as the tint color and specify an alpha value. For instance, tint(255, 128) will make an image 50% transparent (unless colorMode() has been used).
      When using hexadecimal notation to specify a color, use "#" or "0x" before the values (e.g. #CCFFAA, 0xFFCCFFAA). The # syntax uses six digits to specify a color (the way colors are specified in HTML and CSS). When using the hexadecimal notation starting with "0x", the hexadecimal value must be specified with eight characters; the first two characters define the alpha component and the remainder the red, green, and blue components.
      The value for the parameter "gray" must be less than or equal to the current maximum value as specified by colorMode(). The default maximum value is 255.
      The tint() function is also used to control the coloring of textures in 3D. ( end auto-generated )

                          float v2,
                          float v3)

      ( begin auto-generated from ambientLight.xml ) Adds an ambient light. Ambient light doesn't come from a specific direction, the rays have light have bounced around so much that objects are evenly lit from all sides. Ambient lights are almost always used in combination with other types of lights. Lights need to be included in the draw() to remain persistent in a looping program. Placing them in the setup() of a looping program will cause them to only have an effect the first time through the loop. The effect of the parameters is determined by the current color mode. ( end auto-generated )
      Parameters:
        `v1` - red or hue value (depending on current color mode)
        `v2` - green or saturation value (depending on current color mode)

                              float nz)

      ( begin auto-generated from directionalLight.xml ) Adds a directional light. Directional light comes from one direction and is stronger when hitting a surface squarely and weaker if it hits at a a gentle angle. After hitting a surface, a directional lights scatters in all directions. Lights need to be included in the draw() to remain persistent in a looping program. Placing them in the setup() of a looping program will cause them to only have an effect the first time through the loop. The affect of the v1, v2, and v3 parameters is determined by the current color mode. The nx, ny, and nz parameters specify the direction the light is facing. For example, setting ny to -1 will cause the geometry to be lit from below (the light is facing directly upward). ( end auto-generated )
      Parameters:
        `v1` - red or hue value (depending on current color mode)
        `v2` - green or saturation value (depending on current color mode)
        `v3` - blue or brightness value (depending on current color mode)

      ( begin auto-generated from pointLight.xml ) Adds a point light. Lights need to be included in the draw() to remain persistent in a looping program. Placing them in the setup() of a looping program will cause them to only have an effect the first time through the loop. The affect of the v1, v2, and v3 parameters is determined by the current color mode. The x, y, and z parameters set the position of the light. ( end auto-generated )
      Parameters:
        `v1` - red or hue value (depending on current color mode)

                          float linear,
                          float quadratic)

      ( begin auto-generated from lightFalloff.xml ) Sets the falloff rates for point lights, spot lights, and ambient lights. The parameters are used to determine the falloff with the following equation:
      d = distance from light position to vertex position
      falloff = 1 / (CONSTANT + d * LINEAR + (d*d) * QUADRATIC)
      Like fill(), it affects only the elements which are created after it in the code. The default value if LightFalloff(1.0, 0.0, 0.0). Thinking about an ambient light with a falloff can be tricky. It is used, for example, if you wanted a region of your scene to be lit ambiently one color and another region to be lit ambiently by another color, you would use an ambient light with location and falloff. You can think of it as a point light that doesn't care which direction a surface is facing. ( end auto-generated )
      Parameters:
        `constant` - constant value or determining falloff
        `linear` - linear value for determining falloff
        `quadratic` - quadratic value for determining falloff

    - #### lightSpecular

          public void lightSpecular(float v1,
                           float v2,
                           float v3)

      ( begin auto-generated from lightSpecular.xml ) Sets the specular color for lights. Like fill(), it affects only the elements which are created after it in the code. Specular refers to light which bounces off a surface in a perferred direction (rather than bouncing in all directions like a diffuse light) and is used for creating highlights. The specular quality of a light interacts with the specular material qualities set through the specular() and shininess() functions. ( end auto-generated )
      Parameters:
        `v1` - red or hue value (depending on current color mode)
        `v2` - green or saturation value (depending on current color mode)
        `v3` - blue or brightness value (depending on current color mode)

    - #### background

          public void background(int rgb)

      ( begin auto-generated from background.xml ) The background() function sets the color used for the background of the Processing window. The default background is light gray. In the draw() function, the background color is used to clear the display window at the beginning of each frame.
      An image can also be used as the background for a sketch, however its width and height must be the same size as the sketch window. To resize an image 'b' to the size of the sketch window, use b.resize(width, height).
      Images used as background will ignore the current tint() setting.
      It is not possible to use transparency (alpha) in background colors with the main drawing surface, however they will work properly with createGraphics(). ( end auto-generated )

      ### Advanced

      Clear the background with a color that includes an alpha value. This can only be used with objects created by createGraphics(), because the main drawing surface cannot be set transparent.

      It might be tempting to use this function to partially clear the screen on each frame, however that's not how this function works. When calling background(), the pixels will be replaced with pixels that have that level of transparency. To do a semi-transparent overlay, use fill() with alpha and draw a rectangle.

      Parameters:
        `rgb` - any value of the color datatype
      See Also:
        `PGraphics.stroke(float)`, `PGraphics.fill(float)`, `PGraphics.tint(float)`, `PGraphics.colorMode(int)`

          public void background(float gray)

      Parameters:
        `gray` - specifies a value between white and black

                        float v2,
                        float v3)

      Parameters:
        `v1` - red or hue value (depending on the current color mode)
        `v2` - green or saturation value (depending on the current color mode)
        `v3` - blue or brightness value (depending on the current color mode)

                        float alpha)

    - #### clear

          public void clear()

    - #### background

          public void background(PImage image)

      Takes an RGB or ARGB image and sets it as the background. The width and height of the image must be the same size as the sketch. Use image.resize(width, height) to make short work of such a task.
      Note that even if the image is set as RGB, the high 8 bits of each pixel should be set opaque (0xFF000000) because the image data will be copied directly to the screen, and non-opaque background images may have strange behavior. Use image.filter(OPAQUE) to handle this easily.
      When using 3D, this will also clear the zbuffer (if it exists).
      Parameters:
        `image` - PImage to set as background (must be same size as the sketch window)

    - #### colorMode

          public void colorMode(int mode)

      ( begin auto-generated from colorMode.xml ) Changes the way Processing interprets color data. By default, the parameters for fill(), stroke(), background(), and color() are defined by values between 0 and 255 using the RGB color model. The colorMode() function is used to change the numerical range used for specifying colors and to switch color systems. For example, calling colorMode(RGB, 1.0) will specify that values are specified between 0 and 1. The limits for defining colors are altered by setting the parameters range1, range2, range3, and range 4. ( end auto-generated )
      Parameters:
        `mode` - Either RGB or HSB, corresponding to Red/Green/Blue and Hue/Saturation/Brightness
      See Also:

          public void colorMode(int mode,
                       float max1,
                       float max2,
                       float max3)

      Parameters:

                       float max3,
                       float maxA)

      Parameters:
        `maxA` - range for the alpha

    - #### alpha

          public final float alpha(int rgb)

      ( begin auto-generated from alpha.xml ) Extracts the alpha value from a color. ( end auto-generated )
      Parameters:

    - #### red

          public final float red(int rgb)

      ( begin auto-generated from red.xml ) Extracts the red value from a color, scaled to match current colorMode(). This value is always returned as a float so be careful not to assign it to an int value.
      The red() function is easy to use and undestand, but is slower than another technique. To achieve the same results when working in colorMode(RGB, 255), but with greater speed, use the >> (right shift) operator with a bit mask. For example, the following two lines of code are equivalent:

          float r1 = red(myColor);
          float r2 = myColor >> 16
           & 0xFF;

      ( end auto-generated )

    - #### green

          public final float green(int rgb)

      ( begin auto-generated from green.xml ) Extracts the green value from a color, scaled to match current colorMode(). This value is always returned as a float so be careful not to assign it to an int value.
      The green() function is easy to use and undestand, but is slower than another technique. To achieve the same results when working in colorMode(RGB, 255), but with greater speed, use the >> (right shift) operator with a bit mask. For example, the following two lines of code are equivalent:

          float r1 = green(myColor);
          float r2 =
           myColor >> 8 & 0xFF;

      ( begin auto-generated from blue.xml ) Extracts the blue value from a color, scaled to match current colorMode(). This value is always returned as a float so be careful not to assign it to an int value.
      The blue() function is easy to use and undestand, but is slower than another technique. To achieve the same results when working in colorMode(RGB, 255), but with greater speed, use a bit mask to remove the other color components. For example, the following two lines of code are equivalent:

          float r1 = blue(myColor);

                      float amt)

      ( begin auto-generated from lerpColor.xml ) Calculates a color or colors between two color at a specific increment. The amt parameter is the amount to interpolate between the two values where 0.0 equal to the first point, 0.1 is very near the first point, 0.5 is half-way in between, etc. ( end auto-generated )
      Parameters:

      Parameters:
        `method` - The method name (no parentheses)

    - #### showDepthWarningXYZ

          public static void showDepthWarningXYZ(String method)

      Display a warning that the specified method that takes x, y, z parameters can only be used with x and y parameters in this renderer.
      Parameters:
        `method` - The method name (no parentheses)

    - #### showMethodWarning

          public static void showMethodWarning(String method)

      Display a warning that the specified method is simply unavailable.

    - #### showVariationWarning

          public static void showVariationWarning(String str)

      Error that a particular variation of a method is unavailable (even though other variations are). For instance, if vertex(x, y, u, v) is not available, but vertex(x, y) is just fine.

    - #### showMissingWarning

          public static void showMissingWarning(String method)

      Display a warning that the specified method is not implemented, meaning that it could be either a completely missing function, although other variations of it may still work properly.

    - #### displayable

          public boolean displayable()

      Return true if this renderer should be drawn to the screen. Defaults to returning true, since nearly all renderers are on-screen beasts. But can be overridden for subclasses like PDF so that a window doesn't open up.
      A better name? showFrame, displayable, isVisible, visible, shouldDisplay, what to call this?

    - #### isGL

          public boolean isGL()

      Return true if this renderer does rendering through OpenGL. Defaults to false.

    - #### get

          public int get(int x,
                int y)

      ( begin auto-generated from PImage_get.xml ) Reads the color of any pixel or grabs a section of an image. If no parameters are specified, the entire image is returned. Use the x and y parameters to get the value of one pixel. Get a section of the display window by specifying an additional width and height parameter. When getting an image, the x and y parameters define the coordinates for the upper-left corner of the image, regardless of the current imageMode().
      If the pixel requested is outside of the image window, black is returned. The numbers returned are scaled according to the current color ranges, but only RGB values are returned by this function. For example, even though you may have drawn a shape with colorMode(HSB), the numbers returned will be in RGB format.
      Getting the color of a single pixel with get(x, y) is easy, but not as fast as grabbing the data directly from pixels[]. The equivalent statement to get(x, y) using pixels[] is pixels[y*width+x]. See the reference for pixels[] for more information. ( end auto-generated )

      ### Advanced

      Returns an ARGB "color" type (a packed 32 bit int with the color. If the coordinate is outside the image, zero is returned (black, but completely transparent).

      If the image is in RGB format (i.e. on a PVideo object), the value will get its high bits set, just to avoid cases where they haven't been set already.

      If the image is in ALPHA format, this returns a white with its alpha value set.

      This function is included primarily for beginners. It is quite slow because it has to check to see if the x, y that was provided is inside the bounds, and then has to check to see what image type it is. If you want things to be more efficient, access the pixels[] array directly.

      Parameters:
        `x` - x-coordinate of the pixel
        `y` - y-coordinate of the pixel
      See Also:
        `set(int, int, int)`, `pixels`, `copy(PImage, int, int, int, int, int, int, int, int)`

    - #### get

          public PImage get(int x,
                   int y,
                   int w,
                   int h)

      Parameters:
        `w` - width of pixel rectangle to get
        `h` - height of pixel rectangle to get

    - #### get

          public PImage get()

      Returns a copy of this PImage. Equivalent to get(0, 0, width, height).

    - #### set

          public void set(int x,
                 int y,
                 int c)

      ( begin auto-generated from PImage_set.xml ) Changes the color of any pixel or writes an image directly into the display window.
      The x and y parameters specify the pixel to change and the color parameter specifies the color value. The color parameter is affected by the current color mode (the default is RGB values from 0 to 255). When setting an image, the x and y parameters define the coordinates for the upper-left corner of the image, regardless of the current imageMode().
      Setting the color of a single pixel with set(x, y) is easy, but not as fast as putting the data directly into pixels[]. The equivalent statement to set(x, y, #000000) using pixels[] is pixels[y*width+x] = #000000. See the reference for pixels[] for more information. ( end auto-generated )
      Parameters:
        `x` - x-coordinate of the pixel
        `y` - y-coordinate of the pixel
        `c` - any value of the color datatype
      See Also:
        `PImage.get(int, int, int, int)`, `PImage.pixels`, `PImage.copy(PImage, int, int, int, int, int, int, int, int)`

    - #### set

          public void set(int x,
                 int y,
                 PImage img)

      ### Advanced

      Efficient method of drawing an image's pixels directly to this surface. No variations are employed, meaning that any scale, tint, or imageMode settings will be ignored.
      Parameters:
        `img` - image to copy into the original image

    - #### mask

          public void mask(PImage img)

      ( begin auto-generated from PImage_mask.xml ) Masks part of an image from displaying by loading another image and using it as an alpha channel. This mask image should only contain grayscale data, but only the blue color channel is used. The mask image needs to be the same size as the image to which it is applied.
      In addition to using a mask image, an integer array containing the alpha channel data can be specified directly. This method is useful for creating dynamically generated alpha masks. This array must be of the same length as the target image's pixels array and should contain only grayscale data of values between 0-255. ( end auto-generated )

      ### Advanced

      Set alpha channel for an image. Black colors in the source image will make the destination image completely transparent, and white will make things fully opaque. Gray values will be in-between steps.

      Strictly speaking the "blue" value from the source image is used as the alpha color. For a fully grayscale image, this is correct, but for a color image it's not 100% accurate. For a more accurate conversion, first use filter(GRAY) which will make the image into a "correct" grayscale by performing a proper luminance-based conversion.

      Parameters:
        `maskArray` - array of integers used as the alpha channel, needs to be the same length as the image's pixel array

    - #### filter

          public void filter(int kind)

    - #### filter

          public void filter(int kind,
                    float param)

      ( begin auto-generated from PImage_filter.xml ) Filters an image as defined by one of the following modes:
      THRESHOLD - converts the image to black and white pixels depending if they are above or below the threshold defined by the level parameter. The level must be between 0.0 (black) and 1.0(white). If no level is specified, 0.5 is used.
      GRAY - converts any colors in the image to grayscale equivalents
      INVERT - sets each pixel to its inverse value
      POSTERIZE - limits each channel of the image to the number of colors specified as the level parameter
      BLUR - executes a Guassian blur with the level parameter specifying the extent of the blurring. If no level parameter is used, the blur is equivalent to Guassian blur of radius 1
      OPAQUE - sets the alpha channel to entirely opaque
      ERODE - reduces the light areas with the amount defined by the level parameter
      DILATE - increases the light areas with the amount defined by the level parameter ( end auto-generated )

      ### Advanced

      Method to apply a variety of basic filters to this image.

      - filter(BLUR) provides a basic blur.
      - filter(GRAY) converts the image to grayscale based on luminance.
      - filter(INVERT) will invert the color components in the image.
      - filter(OPAQUE) set all the high bits in the image to opaque
      - filter(THRESHOLD) converts the image to black and white.
      - filter(DILATE) grow white/light areas
      - filter(ERODE) shrink white/light areas
      Luminance conversion code contributed by toxi

      Gaussian blur code contributed by Mario Klingemann
      Parameters:
        `kind` - Either THRESHOLD, GRAY, OPAQUE, INVERT, POSTERIZE, BLUR, ERODE, or DILATE
        `param` - unique for each, see above

    - #### copy

          public void copy(int sx,
                  int sy,
                  int sw,
                  int sh,
                  int dx,
                  int dy,
                  int dw,
                  int dh)

      ( begin auto-generated from PImage_copy.xml ) Copies a region of pixels from one image into another. If the source and destination regions aren't the same size, it will automatically resize source pixels to fit the specified target region. No alpha information is used in the process, however if the source image has an alpha channel set, it will be copied as well.
      As of release 0149, this function ignores imageMode(). ( end auto-generated )
      Parameters:
        `sx` - X coordinate of the source's upper left corner
        `sy` - Y coordinate of the source's upper left corner
        `sw` - source image width

                  int dw,
                  int dh)

      Parameters:
        `src` - an image variable referring to the source image.

    - #### blend

          public void blend(int sx,
                   int sy,

                   int dh,
                   int mode)

      ( begin auto-generated from PImage_blend.xml ) Blends a region of pixels into the image specified by the img parameter. These copies utilize full alpha channel support and a choice of the following modes to blend the colors of source pixels (A) with the ones of pixels in the destination image (B):
      BLEND - linear interpolation of colours: C = A*factor + B
      ADD - additive blending with white clip: C = min(A*factor + B, 255)
      SUBTRACT - subtractive blending with black clip: C = max(B - A*factor, 0)
      DARKEST - only the darkest colour succeeds: C = min(A*factor, B)
      LIGHTEST - only the lightest colour succeeds: C = max(A*factor, B)
      DIFFERENCE - subtract colors from underlying image.
      EXCLUSION - similar to DIFFERENCE, but less extreme.
      MULTIPLY - Multiply the colors, result will always be darker.
      SCREEN - Opposite multiply, uses inverse values of the colors.
      OVERLAY - A mix of MULTIPLY and SCREEN. Multiplies dark values, and screens light values.
      HARD_LIGHT - SCREEN when greater than 50% gray, MULTIPLY when lower.
      SOFT_LIGHT - Mix of DARKEST and LIGHTEST. Works like OVERLAY, but not as harsh.
      DODGE - Lightens light tones and increases contrast, ignores darks. Called "Color Dodge" in Illustrator and Photoshop.
      BURN - Darker areas are applied, increasing contrast, ignores lights. Called "Color Burn" in Illustrator and Photoshop.
      All modes use the alpha information (highest byte) of source image pixels as the blending factor. If the source and destination regions are different sizes, the image will be automatically resized to match the destination size. If the srcImg parameter is not used, the display window is used as the source image.
      As of release 0149, this function ignores imageMode(). ( end auto-generated )
      Parameters:
        `src` - an image variable referring to the source image
        `sx` - X coordinate of the source's upper left corner
        `sy` - Y coordinate of the source's upper left corner
        `sw` - source image width
        `sh` - source image height
        `dx` - X coordinate of the destinations's upper left corner
        `dy` - Y coordinate of the destinations's upper left corner
        `dw` - destination image width
        `dh` - destination image height
        `mode` - Either BLEND, ADD, SUBTRACT, LIGHTEST, DARKEST, DIFFERENCE, EXCLUSION, MULTIPLY, SCREEN, OVERLAY, HARD_LIGHT, SOFT_LIGHT, DODGE, BURN
