mlib_ImageConstSub_Fp - Subtraction with a constant
cc [ flag... ] file... –lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageConstSub_Fp(mlib_image *dst, const mlib_image *src, const mlib_d64 *c);
The mlib_ImageConstSub_Fp() function subtracts a floating-point 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]
The function takes the following arguments:
Pointer to destination image.
Pointer to source image.
Array of constants from which each pixel is subtracted by channel. c[i] contains the constant for channel i.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
