A single example is worth a thousand words. Thank you very much Scott!
I now see that statements like the following are perfectly possible:
set alphaData of img display to alphaData of img disc.gif
set imageData of img display to imageData of img grad.png
I suspected that it might be something like that, but part of my
confusion comes from VB where the definition of "mask" is somewhat
different (i.e. the white area in my circle image CAN be read as
transparency).
Regards,
Bob
