cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageThresh4_Fp_Inp(mlib_image *srcdst, const mlib_d64 *thigh, const mlib_d64 *tlow, const mlib_d64 *ghigh, const mlib_d64 *glow);
The mlib_ImageThresh4_Fp_Inp() function compares each pixel in the source image to two threshold values, tlow and thigh. If the pixel is less than the lower threshold value, tlow, then the destination pixel is set to the lower output level, glow. If the pixel is greater than the higher threshold value, thigh, then the destination pixel is set to the higher output level, ghigh. Otherwise, the destination pixel is set to the value of the source pixel.
It uses the following equation:
srcdst[x][y][i] = glow[i] if srcdst[x][y][i] < tlow[i] srcdst[x][y][i] = ghigh[i] if srcdst[x][y][i] > thigh[i]
The function takes the following arguments:
srcdst
thigh
tlow
ghigh
glow
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
