Can bitmaps be transparent in Palm OS 3? In some situations, I have a somewhat messy arrangement of a few bitmaps on top of each other, some transparent, some not. I use an OffScreenWindow and it works fine in any OS greater than 3.
I believe that support for transparent bitmaps was only added in Palm OS 3.5, when we added color support. Prior to that, you could get similar results through use of the drawing modes, e.g. srcOR and so forth.
