public class ComposeShader
extends Shader

java.lang.Object
↳	android.graphics.Shader
	↳	android.graphics.ComposeShader

A subclass of shader that returns the composition of two other shaders, combined by an Xfermode subclass.

Summary

Public constructors
`ComposeShader(Shader shaderA, Shader shaderB, Xfermode mode)` Create a new compose shader, given shaders A, B, and a combining mode.
`ComposeShader(Shader shaderA, Shader shaderB, PorterDuff.Mode mode)` Create a new compose shader, given shaders A, B, and a combining PorterDuff mode.
`ComposeShader(Shader shaderA, Shader shaderB, BlendMode blendMode)` Create a new compose shader, given shaders A, B, and a combining PorterDuff mode.

Inherited methods

From class


        
          android.graphics.Shader

`boolean`	`getLocalMatrix(Matrix localM)` Return true if the shader has a non-identity local matrix.
`void`	`setLocalMatrix(Matrix localM)` Set the shader's local matrix.

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

ComposeShader

Added in API level 1

public ComposeShader (Shader shaderA, 
                Shader shaderB, 
                Xfermode mode)

Create a new compose shader, given shaders A, B, and a combining mode. When the mode is applied, it will be given the result from shader A as its "dst", and the result from shader B as its "src".

Parameters
`shaderA`	`Shader`: The colors from this shader are seen as the "dst" by the mode This value cannot be `null`.
`shaderB`	`Shader`: The colors from this shader are seen as the "src" by the mode This value cannot be `null`.
`mode`	`Xfermode`: The mode that combines the colors from the two shaders. If mode is null, then SRC_OVER is assumed.

Parameters
`shaderA`	`Shader`: The colors from this shader are seen as the "dst" by the mode This value cannot be `null`.
`shaderB`	`Shader`: The colors from this shader are seen as the "src" by the mode This value cannot be `null`.
`mode`	`PorterDuff.Mode`: The PorterDuff mode that combines the colors from the two shaders. This value cannot be `null`.
