Hi all,
I'm using a truecolor 565 color framebuffer drawing graphics
exclusively in black and white, i.e. with GrSetGCBackground(gc, WHITE)
and GrSetGCForeground(gc, BLACK). Everything works fine in GR_MODE_COPY
and GR_MODE_COPYINVERTED (involving only src graphic), but when I use
any other mode which combines src and dst nothing is drawn. For example
if I draw in GR_MODE_XOR mode a black box somewhere over a bigger black
box nothing happens. Am I missing something?
Thanks in advande,
Carlo
