cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageThresh2_Fp(mlib_image *dst, const mlib_image *src, const mlib_d64 *thresh, const mlib_d64 *glow);
The mlib_ImageThresh2_Fp() function compares each pixel in the floating-point source image to a threshold value. If the pixel is less than or equal to the threshold value, then the destination pixel is set to the low output level. If the pixel is greater than the threshold value, then the destination pixel is set to the value of the source pixel.
It uses the following equation:
dst[x][y][i] = glow[i] if src[x][y][i] ≤ thresh[i] dst[x][y][i] = src[x][y][i] if src[x][y][i] > thresh[i]
The function takes the following arguments:
dst
src
thresh
glow
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
