LColorTransform Class

Extends LObject
Defined in: geom/LColorTransform.js:1

Available since 1.9.4

Creates a LColorTransform object for a display object with the specified color channel values and alpha values. The ColorTransform class lets you adjust the color values in a display object. The color adjustment or color transformation can be applied to all four channels: red, green, blue, and alpha transparency. When a ColorTransform object is applied to a display object, a new value for each color channel is calculated like this: ・New red value = (old red value redMultiplier) + redOffset ・New green value = (old green value greenMultiplier) + greenOffset ・New blue value = (old blue value blueMultiplier) + blueOffset ・New alpha value = (old alpha value alphaMultiplier) + alphaOffset If any of the color channel values is greater than 255 after the calculation, it is set to 255. If it is less than 0, it is set to 0. You can use ColorTransform objects in the following ways: ・In the colorTransform parameter of the colorTransform() method of the LBitmapData class
