Hello all,
I am using DJGPP 1.12m4 and CBGRX 1.03. The application, which I am
working on at the moment, reads bitmaps from disk and displays them on a
1024x768 screen using 256 colors.
For this I use the following procedure:
for(x = 0; x < 100)
  for(y = 0; <  100)
  {
    GrPlot(x, y, byte());
  }
This works fine, but looks a bit 'unprofessional' because you can see
how the picture is build up on the screen?
Q: Is there a way to first read the bytes into memory and display
   the picture afterwards (preferrably with one of those
   GrBitBlt() functions)?
   
Thank you for helping,
Armin
