Shader


open class Shader
kotlin.Any
   ↳ android.graphics.Shader

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

Added in API level 1
open fun getLocalMatrix(localM: Matrix): Boolean

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.
Return
Boolean true if the shader has a non-identity local matrix

setLocalMatrix

Added in API level 1
open fun setLocalMatrix(localM: Matrix?): Unit

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
