Shader
extends Object
Shader is the base 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 methods
getLocalMatrix
public boolean getLocalMatrix (Matrix localM)
Return true if the shader has a non-identity local matrix.
Parameters |
localM |
Matrix : Set to the local matrix of the shader, if the shader's matrix is non-null. |
Returns |
boolean |
true if the shader has a non-identity local matrix |
setLocalMatrix
public void setLocalMatrix (Matrix localM)
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.
Parameters |
localM |
Matrix : The shader's new local matrix, or null to specify identity |
