ComposeShader


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

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.

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.

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.

                Shader shaderB, 
                PorterDuff.Mode mode)

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.

mode PorterDuff.Mode: The PorterDuff mode that combines the colors from the two shaders. This value cannot be null.

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.
