This is a different question than the one in the thread “masking question”. I am revealing an image that initially is entirely covered by a mask. The code is based on the tutorial: http://www.actionscript.org/resources/articles/168/1/Dynamic-masking-using-the-drawing-API/Page1.html
I want the program to know what percentage of the mask has been removed. When 90% of the mask has been removed I want it to trigger an event. Is there a simple way to do this? Any suggestions will be greatly appreciated.
Thanks so much … Michael
