NAME

SYNOPSIS

              #include <allegro5/allegro.h>

              ALLEGRO_COLOR al_get_pixel(ALLEGRO_BITMAP *bitmap, int x, int y)


DESCRIPTION
       Get a pixel's color value from the specified bitmap.  This operation is
       slow on non-memory bitmaps.  Consider locking the bitmap if you are
       going to use this function multiple times on the same bitmap.
