Description
After using surface.setSize() to resize window outside setup() invoking save() causes NullPointerException. Also, image of the window frame is saved under chosen filename but it has 0 bytes and .tif extension after .jpg or .png. This only happens when non-default renderer is enabled - P2D, P3D or OPENGL.
Code to replicate:
void setup() {
size(500, 500, P3D); //can also be P2D or OPENGL
}
void draw() {
background(255);
surface.setSize(400, 400);
save("test.png"); //NPE thrown here
exit();
}
