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 floating-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.
