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 con‐
version 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.
