Yes, I know, now that I can make translucent PNGs.

Well. like I said, I wanted full bright gradient colors with transparency in
All Platform mode in this particular project, but translucent in another

Here's what I discovered:

What I wanted was *srcOr* under All Platform inks. When I first tried to
replicate my SC project into Rev, I, of course, had to rebuild the color
graphics. When I tried srcOr with my design, I had it over the background,
and it showed bands in it, i.e., the colors weren't right, which wasn't

That's what sent me on the quest for a translucent or transparent PNG
graphic in All Platform mode. But that turned out not to quite right either.

However, while testing again this morning, I see that if *srcOr* is over a
*white* background, like a white field, it looks like I wanted it to all
along, in this case.

So, I find I must apologize for the anxious posts. The white background made
all the difference, which I didn't see before. I think it will work out OK

Thanks again to everyone.

Ken N.
