NAME
       mlib_ImageDivShift1_Inp - division with shifting, in place

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

       mlib_status mlib_ImageDivShift1_Inp(mlib_image *src1dst, const mlib_image *src2, mlib_s32 shift);

DESCRIPTION
       The  mlib_ImageDivShift1_Inp()  function  divides the second source image into the first source image on a pixel-by-pixel basis.  It scales
       the result by a left shift and writes the result to the destination image on a pixel-by-pixel basis.

       It uses the following equation:

       src1dst[x][y][i] = src1dst[x][y][i] / src2[x][y][i] * 2**shift

       In the case of src2[x][y][i] = 0,

       src1dst[x][y][i] = 0		 if src1dst[x][y][i] = 0
       src1dst[x][y][i] = DATA_TYPE_MAX  if src1dst[x][y][i] > 0
       src1dst[x][y][i] = DATA_TYPE_MIN  if src1dst[x][y][i] < 0

       where DATA_TYPE is MLIB_U8, MLIB_S16, MLIB_U16, or MLIB_S32 for an image of type MLIB_BYTE, MLIB_SHORT, MLIB_USHORT, or	MLIB_INT,  respec-
       tively.

PARAMETERS
       The function takes the following arguments:

       src1dst	       Pointer to first source and destination image.

       src2	       Pointer to second source image.

       shift	       Left shifting factor.  0 <= shift <= 31.

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