mlib_ImageThresh2(3MLIB)				    mediaLib Library Functions					  mlib_ImageThresh2(3MLIB)

NAME

       mlib_ImageThresh2 - image thresholding

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_ImageThresh2(mlib_image *dst, const mlib_image *src, const mlib_s32 *thresh, const mlib_s32 *glow);

DESCRIPTION

       The  mlib_ImageThresh2()  function  compares each pixel in the 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 des-
       tination 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]

PARAMETERS

       The function takes the following arguments:

       dst	       Pointer to destination image.

       src	       Pointer to source 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.
