public class ComposeShader
extends Shader

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

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)

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 must never be null.

shaderB Shader: The colors from this shader are seen as the "src" by the mode

This value must never be null.

mode Xfermode: The mode that combines the colors from the two shaders. If mode is null, then SRC_OVER is assumed.

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 must never be null.

shaderB Shader: The colors from this shader are seen as the "src" by the mode

This value must never be null.

mode PorterDuff.Mode: The PorterDuff mode that combines the colors from the two shaders.

This value must never be null.
