Demonstrates how two images can be combines by using BitmapDta's compare() method. 

  
          public class @ax-graphic-flex-image-effects-04-Flex-CompareTest extends graphic_flex_image_effects_04_Flex_DualImageTest {
Called after two images have been loaded by super class. This creates a third image using compare() with loaded images.
