Provides low level graphics tools such as canvases, color filters, points, and rectangles that let you handle drawing to the screen directly.


SurfaceTexture.OnFrameAvailableListener Callback interface for being notified that a new stream frame is available. 


AvoidXfermode AvoidXfermode xfermode will draw the src everywhere except on top of the opColor or, depending on the Mode, draw only on top of the opColor. 
BitmapFactory Creates Bitmap objects from various sources, including files, streams, and byte-arrays. 
BitmapRegionDecoder BitmapRegionDecoder can be used to decode a rectangle region from an image. 
BitmapShader Shader used to draw a bitmap as a texture. 
BlurMaskFilter This takes a mask, and blurs its edge by the specified radius. 
Camera A camera instance can be used to compute 3D transformations and generate a matrix that can be applied, for instance, on a Canvas
Canvas The Canvas class holds the "draw" calls. 
Color The Color class defines methods for creating and converting color ints. 
ColorFilter A color filter can be used with a Paint to modify the color of each pixel drawn with that paint. 
ColorMatrix 4x5 matrix for transforming the color and alpha components of a Bitmap. 
ColorMatrixColorFilter A color filter that transforms colors through a 4x5 color matrix. 
ComposeShader A subclass of shader that returns the composition of two other shaders, combined by an Xfermode subclass. 
DrawFilter A DrawFilter subclass can be installed in a Canvas. 
LightingColorFilter A color filter that can be used to simulate simple lighting effects. 
MaskFilter MaskFilter is the base class for object that perform transformations on an alpha-channel mask before drawing it. 
Matrix The Matrix class holds a 3x3 matrix for transforming coordinates. 
NinePatch The NinePatch class permits drawing a bitmap in nine or more sections. 
Outline Defines a simple shape, used for bounding graphical regions. 
Paint The Paint class holds the style and color information about how to draw geometries, text and bitmaps. 
Paint.FontMetrics Class that describes the various metrics for a font at a given text size. 
Paint.FontMetricsInt Convenience method for callers that want to have FontMetrics values as integers. 
Path The Path class encapsulates compound (multiple contour) geometric paths consisting of straight line segments, quadratic curves, and cubic curves. 
PathEffect PathEffect is the base class for objects in the Paint that affect the geometry of a drawing primitive before it is transformed by the canvas' matrix and drawn. 
Picture A Picture records drawing calls (via the canvas returned by beginRecording) and can then play them back into Canvas (via draw(Canvas) or drawPicture(Picture)).For most content (e.g. 
PixelXorXfermode PixelXorXfermode implements a simple pixel xor (op ^ src ^ dst). 
Point Point holds two integer coordinates  
PointF PointF holds two float coordinates  
PorterDuffColorFilter A color filter that can be used to tint the source pixels using a single color and a specific Porter-Duff composite mode
Rect Rect holds four integer coordinates for a rectangle. 
RectF RectF holds four float coordinates for a rectangle. 
Shader Shader is the based class for objects that return horizontal spans of colors during drawing. 
SurfaceTexture Captures frames from an image stream as an OpenGL ES texture. 
Typeface The Typeface class specifies the typeface and intrinsic style of a font. 
Xfermode Xfermode is the base class for objects that are called to implement custom "transfer-modes" in the drawing pipeline. 
YuvImage YuvImage contains YUV data and provides a method that compresses a region of the YUV data to a Jpeg. 


Bitmap.CompressFormat Specifies the known formats a bitmap can be compressed into  
Bitmap.Config Possible bitmap configurations. 
Matrix.ScaleToFit Controlls how the src rect should align into the dst rect for setRectToRect(). 
Paint.Align Align specifies how drawText aligns its text relative to the [x,y] coordinates. 
Paint.Cap The Cap specifies the treatment for the beginning and ending of stroked lines and paths. 
Paint.Join The Join specifies the treatment where lines and curve segments join on a stroked path. 
Paint.Style The Style specifies if the primitive being drawn is filled, stroked, or both (in the same color). 
Path.Direction Specifies how closed shapes (e.g. 
Path.FillType Enum for the ways a path may be filled. 
Path.Op The logical operations that can be performed when combining two paths.
