: I simplified the original description somewhat - there are actually
: several sprites. oldpxm and newpxm in the above code just make sure that
: we erase the one already on the screen, then put up the new one. This
: all works with (dare I say) real X.
:
: I've compiled microwindows with config.X11 and with the following changes:
: ...
: # define MWPF_TRUECOLOR888 /* pixel is packed 24 bits 8/8/8 truecolor*/
: ...
: SCREEN_PIXTYPE = MWPF_TRUECOLOR888# X Window screen, mouse and
: kbd drivers
: ...
: SCREEN_WIDTH = 320
: SCREEN_HEIGHT = 240
: SCREEN_DEPTH = 8
I still can't make sense of the above. Are you running on X11?
If so, then the screen depth (8) above is ignored, and the X11
server bpp is used. If this is the case, then we need to
look at the drivers/scr_x11.c::X11_blit entry point.
If you're not running on X11, and instead running on a 8bpp system,
then I don't understand the MWPF_TRUECOLOR888.
