| 绘制图片 | drawBitmap, drawPicture | 绘制位图和图片<br/>**相关链接:** <br/>[【Canvas－图片文字】](https://github.com/GcsSloop/AndroidNote/blob/master/CustomView/Advance/%5B4%5DCanvas_PictureText.md) |

| 绘制文本 | drawText, drawPosText, drawTextOnPath | 依次为 绘制文字、绘制文字时指定每个文字位置、根据路径绘制文字<br/>**相关链接:** <br/>[【Canvas－图片文字】](https://github.com/GcsSloop/AndroidNote/blob/master/CustomView/Advance/%5B4%5DCanvas_PictureText.md) |

| 绘制路径 | drawPath | 绘制路径，绘制贝塞尔曲线时也需要用到该函数 <br/>**相关链接:** <br/> [【Path－基本操作】](https://github.com/GcsSloop/AndroidNote/blob/master/CustomView/Advance/%5B5%5DPath_Basic.md) <br/> [【Path－贝塞尔曲线】](https://github.com/GcsSloop/AndroidNote/blob/master/CustomView/Advance/%5B6%5DPath_Bezier.md) <br/> [【Path－完结篇(伪)】](https://github.com/GcsSloop/AndroidNote/blob/master/CustomView/Advance/%5B7%5DPath_Over.md) <br/> [【Path－Path玩出花样(PathMeasure)】](https://github.com/GcsSloop/AndroidNote/blob/master/CustomView/Advance/%5B08%5DPath_Play.md) |

| 顶点操作 | drawVertices, drawBitmapMesh | 通过对顶点操作可以使图像形变，drawVertices直接对画布作用、 drawBitmapMesh只对绘制的Bitmap作用 |

| 画布剪裁 | clipPath, clipRect | 设置画布的显示区域 |

| 画布快照 | save, restore, saveLayerXxx, restoreToCount, getSaveCount | 依次为 保存当前状态、 回滚到上一次保存的状态、 保存图层状态、 会滚到指定状态、 获取保存次数<br/>**相关链接:** <br/>[【Canvas－画布操作】](https://github.com/GcsSloop/AndroidNote/blob/master/CustomView/Advance/%5B3%5DCanvas_Convert.md) |

| 画布变换 | translate, scale, rotate, skew | 依次为 位移、缩放、 旋转、错切<br/> **相关链接:** <br/>[【基础－坐标系】](https://github.com/GcsSloop/AndroidNote/blob/master/CustomView/Base/%5B1%5DCoordinateSystem.md) <br/>[【基础－角度弧度】](https://github.com/GcsSloop/AndroidNote/blob/master/CustomView/Base/%5B2%5DAngleAndRadian.md) <br/>[【Canvas－画布操作】](https://github.com/GcsSloop/AndroidNote/blob/master/CustomView/Advance/%5B3%5DCanvas_Convert.md) |

| Matrix(矩阵) | getMatrix, setMatrix, concat | 实际画布的位移，缩放等操作的都是图像矩阵Matrix，只不过Matrix比较难以理解和使用，故封装了一些常用的方法。<br/>[【Matrix－原理】](https://github.com/GcsSloop/AndroidNote/blob/master/CustomView/Advance/%5B09%5DMatrix_Basic.md) |
