I'm trying to use a black and white bitmap as a mask to selectively erase parts of the window. I'm running into a problem with an inconsistency in behavior using winErase, winMask, and winOverlay. The two perform differently on the Zire 71 and the Tungsten C simulators. In particular:
using winOverlay and the WinCopyRectangle routine: on the Zire 71 simulator: (source) * (dest) = (output) black * color = color white * color = white on the Tungsten C simulator: black * color = black white * color = white Why are these performing differently? Both simulators report having Palm OS 4.5. I have read about the transparancy bit, but since I am using an offscreen window, it should not have one (or at least it should be the same). Any ideas? I am open to suggestions on how to achieve the result using a different method, but I cannot think of a simpler way. In all instances, the foreground and text color was black and background color was white.
