create_bitmap(3) Allegro manual create_bitmap(3) NAME create_bitmap - Creates a memory bitmap. Allegro game programming library. SYNOPSIS #include <allegro.h> BITMAP *create_bitmap(int width, int height); DESCRIPTION Creates a memory bitmap sized width by height. The bitmap will have clip- ping turned on, and the clipping rectangle set to the full size of the bitmap. The image memory will not be cleared, so it will probably contain garbage: you should clear the bitmap before using it. This routine always uses the global pixel format, as specified by calling set_color_depth(). The minimum height of the BITMAP must be 1 and width can't be negative. Example: /* Create a 10 pixel tall bitmap, as wide as the screen. */ BITMAP *bmp = create_bitmap(SCREEN_W, 10); if (!bmp) abort_on_error("Couldn't create bitmap!"); /* Use the bitmap. */ ... /* Destroy it when we don't need it any more. */ destroy_bitmap(bmp); 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.
