Progressive Copy Of All matching Pixels Of specified color in one image to another Attach to any bitmap Sprite (Source Image), when clicked upon a certain point on the sprite all the pixels of the same color will be copied into another image. The size of the bitmap to which pix are being copied should be lagrer than or equal to the source. There is only one parameter in the behaviour... just fill in the Destination bitmap member number. Place both the images on stage and click on any point on the source bitmap sprite....No unnecessary checking and other code has been added for simplicity.
