Constructor Detail

ComposeShader

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 of from shader B as its "src".

Parameters:

shaderA - The colors from this shader are seen as the "dst" by the mode

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

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

ComposeShader

public ComposeShader(Shader shaderA,
                     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 of from shader B as its "src".

Parameters:

shaderA - The colors from this shader are seen as the "dst" by the mode

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

mode - The PorterDuff mode that combines the colors from the two shaders.
