#include <allegro5/allegro.h> ALLEGRO_BITMAP *al_load_bitmap_f(ALLEGRO_FILE *fp, const char *ident)
Loads an image from an ALLEGRO_FILE(3alleg5) stream into an ALLEGRO_BITMAP(3alleg5). The file type is determined by the passed \[aq]ident\[aq] parameter, which is a file name extension including the leading dot.
Returns NULL on error. The file remains open afterwards.
Note: the core Allegro library does not support any image file formats by default. You must use the allegro_image addon, or register your own format handler.
