BOBs or Blitter OBjects are just rectangular gfx drawn by the system. With gfxcard you can use BltBitMap family routines (see graphics.doc). Note that you'll need to handle background restoration yourself (if you need any).

In fact with modern gfx boards BOBs are faster and more versatile than sprites. But I know you knew this already :-)

@ Piru

There's a tool on Aminet (and included with Amikit) called GfxCon that converts between many different formats, including what it calls "RGB-Raw." I've no clue if this is ARGB or RGBA format, but I suspect I'll find out once I begin to experiment with it.

All right, following up on this, I took Piru's example and changed the part where he populated the array variable with this bit of code:

Code: [Select]

     while(!done) {
          UBYTE a; if (!done) if (!(a = fgetc(test))) done = TRUE;
          UBYTE r; if (!done) if (!(r = fgetc(test))) done = TRUE;
          UBYTE g; if (!done) if (!(g = fgetc(test))) done = TRUE;
          UBYTE b; if (!done) if (!(b = fgetc(test))) done = TRUE;
          if (!done) array[y * WIDTH + x] = (r << 16) | (g << 8) | b;
      }

Unfortunately, and not unexpectedly, all I got was garbage. I even switched the "UBYTE a" variable from first to last to account for the differences between ARGB and RGBA. I may be approaching this completely wrong and may have made a number of bad assumptions. As always, if ya gots some clues, please enlighten me. :-)

I figured it out... The raw format I was using has no alpha channel, so it was simple RGB, not RGBA or ARGB. Also, I needed to redefine char to UBYTE, like so:

Code: [Select]

         UBYTE r = (UBYTE)fgetc(test);
          UBYTE g = (UBYTE)fgetc(test);
          UBYTE b = (UBYTE)fgetc(test);
