#include <allegro.h>

int bitmap_color_depth(BITMAP *bmp);

Returns the color depth of the specified bitmap (8, 15, 16, 24, or 32). Example:

   switch (bitmap_color_depth(screen)) {
      case 8:
         /* Access screen using optimized 8-bit code. */
         break;
      default:
         /* Use generic slow functions. */
         break;
   }
