mediaLib Library Functions mlib_ImageColorConvert2_Fp(3MLIB)
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_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.
