SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageThresh1_Fp_Inp(mlib_image *srcdst,
const mlib_d64 *thresh, const mlib_d64 *ghigh, const mlib_d64 *glow);
DESCRIPTION
The mlib_ImageThresh1_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 destina‐
tion 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 high out‐
put level.
It uses the following equation:
srcdst[x][y][i] = glow[i] if srcdst[x][y][i] ≤ thresh[i]
srcdst[x][y][i] = ghigh[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.
ghigh High output level. ghigh[i] contains the high output level
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.
