Need help: losing transparent color on 2 color images

Altough I have not used GapiDraw for a while I think I know what your problem is. The RGB macro works with 24-bit color and for example on a Pocket PC the color depth is only 16 bits. This means that RGB(1,1,1) will be the same color as RGB(0,0,0).
However I see that you are testing your work on a PC and I am not sure what color depth GapiDraw uses there. GapiDraw can very well be using 16 bit color representation there also to allow optimizations.

Thanks for the reponse.

The netpbm tools made it easy enough to test a theory. I remapped all RGB(1,1,1) to rgb(255,0,255) and changed my color key and the black masks started working.

The oddity I see is that this only seemed to affect my 2 color images. I used 1,1,1 with other images that had more colors and the masking worked fine, and many of the images contained color 0,0,0 as well, which stayed intact. But when I use those 2 in a 2 color image, the file that loaded had its 1,1,1 pixels converted to 0,0,0.

There is something not quite right in the loading of 2 color images.
