ShaderFactory
abstract class ShaderFactory
Base class defines a factory object that is called each time the drawable is resized (has a new width or height). Its resize() method returns a corresponding shader, or null. Implement this class if you'd like your ShapeDrawable to use a special android.graphics.Shader, such as a android.graphics.LinearGradient.

abstract fun resize(
width: Int,
height: Int
): Shader!
Returns the Shader to be drawn when a Drawable is drawn. The dimensions of the Drawable are passed because they may be needed to adjust how the Shader is configured for drawing. This is called by ShapeDrawable.setShape().
| Parameters |
width |
Int: the width of the Drawable being drawn |
height |
Int: the heigh of the Drawable being drawn |
| Return |
