You must have missed this post from Ken yesterday -- sounds like just what the doctor ordered: ------------------------------------------------------------------------- From: Ken Ray * Subject: Fun With ImageData, MaskData and AlphaData * Date: Tue, 02 Jul 2002 22:14:19 -0700 ------------------------------------------------------------------------ Just wanted to let you all know that I've been working with these cool image-manipulation features of MetaCard and wrapped my head around them enough to write up a treatise on how to use them along with some examples. Here's the relevant links to the Tips section of the MetaCard page of my site to those who are interested : http://www.sonsothunder.com/devres/metacard/metacard.htm Click on the following links: imag003 - Understanding ImageData, MaskData and AlphaData imag004 - Making a Single Color Transparent Using MaskData imag005 - Making an Image Translucent Using AlphaData Enjoy!
