NAME
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);
DESCRIPTION
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. */
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.
