#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.
