NAME
       mlib_ImageThresh3_Fp - image thresholding

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

       mlib_status mlib_ImageThresh3_Fp(mlib_image *dst, const mlib_image *src,
	    const mlib_d64 *thresh, const mlib_d64 *ghigh);

DESCRIPTION
       The  mlib_ImageThresh3_Fp() function compares each pixel in the floating-point 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 value of the source pixel. If	the  pixel  is	greater  than  the
       threshold value, then the destination pixel is set to the high output level.

       It uses the following equation:

	 dst[x][y][i] = src[x][y][i]  if src[x][y][i] <= thresh[i]
	 dst[x][y][i] = ghigh[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.

       ghigh	 High output level. ghigh[i] contains the high output level for channel i.

RETURN VALUES
       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
