Shader

public class Shader extends Object
Shader is the based class for objects that return horizontal spans of colors during drawing. A subclass of Shader is installed in a Paint calling paint.setShader(shader). After that any object (other than a bitmap) that is drawn with that paint will get its color(s) from the shader.

public booleangetLocalMatrix(Matrix localM)
Return true if the shader has a non-identity local matrix.

param
localM If not null, it is set to the shader's local matrix.

public voidsetLocalMatrix(Matrix localM)
Set the shader's local matrix. Passing null will reset the shader's
matrix to identity
param
localM The shader's new local matrix, or null to specify identity
