NAME
       mlib_ImageConstSub - Subtraction with a constant

SYNOPSIS
       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_ImageConstSub(mlib_image *dst, const mlib_image *src,
	    const mlib_s32 *c);

DESCRIPTION
       The mlib_ImageConstSub() function subtracts an image pixel from a constant on a pixel-by-pixel basis.

       It uses the following equation:

	 dst[x][y][i] = c[i] - src[x][y][i]

PARAMETERS
       The function takes the following arguments:

       dst    Pointer to destination image.

       src    Pointer to source image.

       c      Array of constants from which each pixel is subtracted by channel. c[i] contains the constant for channel i.

RETURN VALUES
       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
