NAME
mlib_ImageThresh2_Fp_Inp - image thresholding
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_ImageThresh2_Fp_Inp(mlib_image *srcdst, const mlib_d64 *thresh, const mlib_d64 *glow);
DESCRIPTION
The mlib_ImageThresh2_Fp_Inp() function compares each pixel in the floating-point source image to a threshold value, in place. 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: srcdst[x][y][i] = glow[i] if srcdst[x][y][i] <= thresh[i]
PARAMETERS
The function takes the following arguments: srcdst Pointer to source and destination image. thresh Threshold value. thresh[i] contains the threshold for channel i. glow Low output level. glow[i] contains the low output level for channel i.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
