mlib_status mlib_ImageColorConvert1(mlib_image *dst, const mlib_image *src,
     const mlib_d64 *cmat);

Description

The mlib_ImageColorConvert1() function takes a 3x3 floating-point conversion matrix 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]|
|dst[x][y][1]| = |cmat[3] cmat[4] cmat[5]| * |src[x][y][1]|
|dst[x][y][2]|   |cmat[6] cmat[7] cmat[8]|   |src[x][y][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.

Return Values

The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
