create_bitmap_ex man page

create_bitmap_ex — Creates a memory bitmap specifying color depth. Allegro game programming library.


#include <allegro.h>

BITMAP *create_bitmap_ex(int color_depth, int width, int height);


Creates a bitmap in a specific color depth (8, 15, 16, 24 or 32 bits per  pixel). Example:

   /* Create screen sized bitmap in 32 bits per pixel. */
   BITMAP *bmp = create_bitmap_ex(32, SCREEN_W, SCREEN_H);
   if (!bmp)
      abort_on_error("Couldn't create bitmap!");
   /* Use the bitmap. */
   /* Destroy it when we don't need it any more. */

Return Value

Returns a pointer to the created bitmap, or NULL if the bitmap could not be created. Remember to free this bitmap later to avoid memory leaks.
