Adjusting DisplayObject colors

You can use the methods of the ColorTransform class (flash.geom.ColorTransform) to adjust the color of a display object. Each display object has a transform property, which is an instance of the Transform class, and contains information about various transformations that are applied to the display object (such as rotation, changes in scale or position, and so forth). In addition to its information about geometric transformations, the Transform class also includes a colorTransform property, which is an instance of the ColorTransform class, and provides access to make color adjustments to the display object. To access the color transformation information of a display object, you can use code such as this:

var colorInfo:ColorTransform = myDisplayObject.transform.colorTransform;

Once you've created a ColorTransform instance, you can read its property values to find out what color transformations have already been applied, or you can set those values to make color changes to the display object. To update the display object after any changes, you must reassign the ColorTransform instance back to the transform.colorTransform property.

var colorInfo:ColorTransform = my DisplayObject.transform.colorTransform;

// Make some color transformations here.

// Commit the change.
myDisplayObject.transform.colorTransform = colorInfo;
