LuminosityMaskShader

Package | mx.graphics.shaderClasses
Class | public class LuminosityMaskShader
Inheritance | LuminosityMaskShader flash.display.Shader

Language Version : | ActionScript 3.0

Product Version : | Flex 4

Runtime Versions : | Flash Player 10, AIR 1.5

Creates a blend shader that is equivalent to the luminosity masking option (also known as soft masking) available in Adobe Creative Suite tools. This mask type is not native to Flash, but is available in tools like Adobe Illustrator and Adobe Photoshop.

A luminosity mask type can be set on Flex groups and graphic elements. The visual appearance in tools like Adobe Illustrator and Adobe Photoshop will be mimicked through this blend shader.

Runtime Versions : | Flash Player 10, AIR 1.5

A convenience field that takes into account whether luminosityClip and/or luminosityInvert are on or off.

- mode 0 = luminosityClip off, luminosityInvert off
- mode 1 = luminosityClip off, luminosityInvert on
- mode 2 = luminosityClip on, luminosityInvert off
- mode 3 = luminosityClip on, luminosityInvert on
