NAME
       mlib_ImageColorConvert2_Fp - 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_Fp(mlib_image *dst,
	    const mlib_image *src, const mlib_d64 *cmat,
	    const mlib_d64 *offset);

DESCRIPTION
       The  mlib_ImageColorConvert2_Fp()  function takes a 3x3 floating-point conversion matrix and a three-element offset and converts the float-
       ing-point 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.
