#include <mlib.h>
mlib_status mlib_ImageColorConvert2_Fp(mlib_image *dst,
const mlib_image *src, const mlib_d64 *cmat,
const mlib_d64 *offset);
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]|
The function takes the following arguments:
Pointer to destination image.
Pointer to source image.
Conversion matrix in row major order.
Offset array.
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
