Kotlin |Java

open class ComposeShader : Shader

kotlin.Any
↳	android.graphics.Shader
	↳	android.graphics.ComposeShader

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

Summary

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

Inherited functions
From class Shader Boolean getLocalMatrix(localM: Matrix) Return true if the shader has a non-identity local matrix. Unit setLocalMatrix(localM: Matrix?) Set the shader's local matrix. Passing null will reset the shader's matrix to identity. If the matrix has scale value as 0, the drawing result is undefined.

ComposeShader

Added in API level 29

ComposeShader(
    shaderA: Shader, 
    shaderB: Shader, 
    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.

ComposeShader(
    shaderA: Shader, 
    shaderB: Shader, 
    mode: PorterDuff.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.

ComposeShader

Added in API level 1

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

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.
