Example
The following example concatenates the ColorTransform object
colorTrans_2 to
colorTrans_1 resulting in a full red offset combined with a .5 alpha multiplier.
import flash.geom.ColorTransform;
import flash.geom.Transform;
var colorTrans_1:ColorTransform = new ColorTransform(1, 1, 1, 1, 255, 0, 0,
0);
trace(colorTrans_1);
// (redMultiplier=1, greenMultiplier=1, blueMultiplier=1,
alphaMultiplier=1, redOffset=255, greenOffset=0, blueOffset=0,
alphaOffset=0)
var colorTrans_2:ColorTransform = new ColorTransform(1, 1, 1, .5, 0, 0, 0,
0);
trace(colorTrans_2);
// (redMultiplier=1, greenMultiplier=1, blueMultiplier=1,
alphaMultiplier=0.5, redOffset=0, greenOffset=0, blueOffset=0,
alphaOffset=0)
colorTrans_1.concat(colorTrans_2);
trace(colorTrans_1);
// (redMultiplier=1, greenMultiplier=1, blueMultiplier=1,
alphaMultiplier=0.5, redOffset=255, greenOffset=0, blueOffset=0,
alphaOffset=0)
var rect:MovieClip = createRectangle(20, 80, 0x000000);
var trans:Transform = new Transform(rect);
trans.colorTransform = colorTrans_1;
function createRectangle(width:Number, height:Number, color:Number,
scope:MovieClip):MovieClip {
scope = (scope == undefined) ? this : scope;
var depth:Number = scope.getNextHighestDepth();
var mc:MovieClip = scope.createEmptyMovieClip("mc_" + depth, depth);
mc.beginFill(color);
mc.lineTo(0, height);
mc.lineTo(width, height);
mc.lineTo(width, 0);
mc.lineTo(0, 0);
return mc;
