Dear Rick I experimented with this problem and it seems to have a really straightforward solution (unless I misunderstand the problem) ...
I created empty image areas on a card and then used the "fill" tool (in the graphics tools at the bottom of the toolbox) to fill them with colors (e.g. red, green & blue). If I then set the "blend" property to "on" by checking the box on the property inspector for each image area, I could manually set their opacity using the slider on the property inspector, or in a script, by using a command of the form: set the blendLevel of image "myImage" to 50 This seems to have the desired effect for creating colored semi-transparent filters. I guess the colors are innacurate unless you do some more fancy screen calibration - but is this what you were trying to achieve? Best Gordon --- "Frank D.
