NAME
mlib_ImageCopyMask - copy with mask
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 threshold for channel i.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
