create_video_bitmap(3) - Linux man page
Name
create_video_bitmap - Creates a video memory bitmap. Allegro game programming library.
Synopsis
#include <allegro.h>
BITMAP *create_video_bitmap(int width, int height);
Description
Allocates a video memory bitmap of the specified size. This can be used to allocate offscreen video memory
for storing source graphics ready for a hardware accelerated blitting operation, or to create multiple video memory pages which can then be displayed by
calling show_video_bitmap(). Read the introduction of this chapter for a comparison with other types of bitmaps and other specific details.
Warning: video memory bitmaps are usually allocated from the same space as the screen bitmap, so they may overlap with it; it is therefore not a good idea
to use the global screen at the same time as any surfaces returned by this function.
Return Value
Returns a pointer to the bitmap on success, or NULL if you have run out of video ram. Remember to destroy
this bitmap before any subsequent call to set_gfx_mode().
