I see. In that case, I suggest you find some tutorials on 
software rendering in C or C++ and adapt them to D. Most of the 
modern stuff out there is going to be targeting 24-bit or 32-bit 
graphics. You might find some older tutorials on indexed 8-bit 
rendering that you can adapt to 4-bit. Nothing to it but storing 
the palette indices in a byte array.
