After calling set_trans_blender(), set_blender_mode(), or any of the other…
create_bitmap_ex – Creates a memory bitmap specifying color depth. Allegro game programming library. Synopsis#include <allegro.h> BITMAP *create_bitmap_ex(int color_depth, int width, int height); DescriptionCreates 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,…
create_bitmap – Creates a memory bitmap. Allegro game programming library. Synopsis#include <allegro.h> BITMAP *create_bitmap(int width, int height); DescriptionCreates a memory bitmap sized width by height. The bitmap will have clipping 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…
