_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.
