SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_ImageThresh1_Inp(mlib_image *srcdst,
const mlib_s32 *thresh, const mlib_s32 *ghigh, const mlib_s32 *glow);
DESCRIPTION
The mlib_ImageThresh1_Inp() function compares each pixel in the image
to a threshold value on a per-channel basis. If the pixel is less than
or equal to the threshold value, then it is reset to the low output
level. If the pixel is greater than the threshold value, then it is
reset to the high output 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.
