NAME
       mlib_ImageColorConvert2 - color conversion using a 3x3 floating-point matrix and a three-element offset

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

       mlib_status mlib_ImageColorConvert2(mlib_image *dst, const mlib_image *src, const mlib_d64 *cmat, const mlib_d64 *offset);

DESCRIPTION
       The  mlib_ImageColorConvert2()  function  takes	a  3x3 floating-point conversion matrix and a three-element offset and converts the source
       color image to the destination color image.

       The source and destination images must be three-channel images.

       It uses the following equation:

       |dst[x][y][0]|	|cmat[0] cmat[1] cmat[2]|   |src[x][y][0]|   |offset[0]|
       |dst[x][y][1]| = |cmat[3] cmat[4] cmat[5]| * |src[x][y][1]| + |offset[1]|
       |dst[x][y][2]|	|cmat[6] cmat[7] cmat[8]|   |src[x][y][2]|   |offset[2]|

PARAMETERS
       The function takes the following arguments:

       dst	       Pointer to destination image.

       src	       Pointer to source image.

       cmat	       Conversion matrix in row major order.

       offset	       Offset array.

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