_getpixel(3)                    Allegro manual                    _getpixel(3)

NAME
       _getpixel, _getpixel15, _getpixel16, _getpixel24, _getpixel32 - Faster
       specific version of getpixel(). Allegro game programming library.

SYNOPSIS
       #include <allegro.h>

       int _getpixel(BITMAP *bmp, int x, int y);

       int _getpixel15(BITMAP *bmp, int x, int y);

       int _getpixel16(BITMAP *bmp, int x, int y);

       int _getpixel24(BITMAP *bmp, int x, int y);

       int _getpixel32(BITMAP *bmp, int x, int y);

DESCRIPTION
       Faster inline versions of getpixel() for specific color depths. These
       won't work in mode-X, and don't do any clipping, so you must make sure
       the point lies inside the bitmap.

RETURN VALUE
       Returns the value of the pixel in the color format you specified.
