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, BlendMode blendMode)` Create a new compose shader, given shaders A, B, and a combining PorterDuff 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, Xfermode mode)` Create a new compose shader, given shaders A, B, and a combining 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.

Public constructors

ComposeShader

Added in API level 29

public ComposeShader (Shader shaderA, 
                Shader shaderB, 
                BlendMode blendMode)

Create a new compose shader, given shaders A, B, and a combining PorterDuff 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`.
`blendMode`	`BlendMode`: The blend mode that combines the colors from the two shaders. This value cannot be `null`.

Added in API level 1

public ComposeShader (Shader shaderA, 
                Shader shaderB, 
                PorterDuff.Mode mode)

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`.

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.
