Hello elibol, Will your function (class?) be For Flash 8 only (as bitmapData was mentioned)? I think this all can be done flash 7 compatible.
Well, I'm very interested. If you'll need some help with testing and/or making a component for non-programmers, don't hesitate to email me. -- Best regards, GregoryN ================================ http://GOusable.com Flash components development.
