cc [ flag... ] file... –lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageCopyMask_Fp(mlib_image *dst, const mlib_image *src, const mlib_image *mask, const mlib_d64 *thresh);
The mlib_ImageCopyMask_Fp() 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_FLOAT or MLIB_DOUBLE.
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]
The function takes the following arguments:
Pointer to destination image.
Pointer to source image.
Pointer to mask image.
Threshold for the mask image. thresh[i] contains the threshold for channel i.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
