SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageCopyMask(mlib_image *dst, const mlib_image *src,
const mlib_image *mask, const mlib_s32 *thresh);
DESCRIPTION
The mlib_ImageCopyMask() function copies one image to another image via
a mask image by using it as a yes/no indicator. The data type of the
images can be MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, or MLIB_INT.
It uses the following equation:
dst[x][y][i] = src[x][y][i] if mask[x][y][i] ≤ thresh[i]
dst[x][y][i] = dst[x][y][i] if mask[x][y][i] > thresh[i]
PARAMETERS
The function takes the following arguments:
dst Pointer to destination image.
src Pointer to source image.
mask Pointer to mask image.
thresh Threshold for the mask image. thresh[i] contains the thresh‐
old for channel i.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns
MLIB_FAILURE.
