NAME

       mlib_ImageLookUp_Inp - table lookup, in place

SYNOPSIS

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

       mlib_status mlib_ImageLookUp_Inp(mlib_image *srcdst, const void **table);

DESCRIPTION

       The mlib_ImageLookUp_Inp() function maps the source image to the destination image, in place, by using the user-specified lookup table.

       The following equation is used:

       srcdst[x][y][i] = table[i][srcdst[x][y][i]]

PARAMETERS

       The function takes the following arguments:

       srcdst	       Pointer to first source and destination image.

       table	       Pointer	to  lookup table. The data type of the lookup table is the same as the destination image. The number of entries in
		       the lookup table is determined by the type of the input image. The format of the lookup table is:

		       table[channel][index]

		       The MLIB_BYTE type entries are indexed from 0 to 255. The MLIB_SHORT type entries are indexed from -32768 to -1, then  from
		       0  to  32767.  The  MLIB_USHORT	type  entries  are  indexed  from  0  to 65535. The MLIB_INT type entries are indexed from
		       -2147483648 to -1, and then from 0 to 2147483647.

RETURN VALUES

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