no bug :)) i am sure of it :))
all my 1bpp, 2bpp and 4bpp images are version 1.0 bitmap images - and
hence i dont assign any "transparency" to em :)
the general behavior of WinDrawBitmap() is to assume that with 1bpp
bitmaps that white is transparent. however, the same is not done with
2bpp and 4bpp.
what i have done to get it working correctly, is actually set the
transparency info in the bitmap in pilrc.
the problem i have is that if i DONT do this, only 1bpp bitmaps
assume that white is transparent.
cheers.
