Color 323
setTransform (Color.setTransform method)
public setTransform(transformObject:Object) : Void
Sets color transform information for a Color object. The colorTransformObject parameter
is a generic object that you create from the
new Object constructor. It has parameters
specifying the percentage and offset values for the red, green, blue, and alpha (transparency)
components of a color, entered in the format 0xRRGGBBAA.
The parameters for a color transform object correspond to the settings in the Advanced Effect
dialog box and are defined as follows:
■ ra is the percentage for the red component (-100 to 100).
■ rb is the offset for the red component (-255 to 255).
■ ga is the percentage for the green component (-100 to 100).
■ gb is the offset for the green component (-255 to 255).
■ ba is the percentage for the blue component (-100 to 100).
■ bb is the offset for the blue component (-255 to 255).
■ aa is the percentage for alpha (-100 to 100).
■ ab is the offset for alpha (-255 to 255).
You create a
colorTransformObject parameter as follows:
var myColorTransform:Object = new Object();
myColorTransform.ra = 50;
myColorTransform.rb = 244;
myColorTransform.ga = 40;
myColorTransform.gb = 112;
myColorTransform.ba = 12;
myColorTransform.bb = 90;
myColorTransform.aa = 40;
myColorTransform.ab = 70;
You can also use the following syntax to create a colorTransformObject parameter:
var myColorTransform:Object = { ra: 50, rb: 244, ga: 40, gb: 112, ba: 12,
bb: 90, aa: 40, ab: 70}
