Details

cd_it8_utils_calculate_ccmx ()

gboolean            cd_it8_utils_calculate_ccmx         (CdIt8 *it8_reference,
                                                         CdIt8 *it8_measured,
                                                         CdIt8 *it8_ccmx,
                                                         GError **error);

This calculates the colorimeter correction matrix using the Four-Color Matrix Method by Yoshihiro Ohno and Jonathan E. Hardis, 1997.

`it8_reference` :	The reference data
`it8_measured` :	The measured data
`it8_ccmx` :	The calculated correction matrix
`error` :	A GError, or `NULL`
Returns :	`TRUE` if a correction matrix was found.

cd_it8_utils_calculate_xyz_from_cmf ()

gboolean            cd_it8_utils_calculate_xyz_from_cmf (CdIt8 *cmf,
                                                         CdSpectrum *illuminant,
                                                         CdSpectrum *spectrum,
                                                         CdColorXYZ *value,
                                                         gdouble resolution,
                                                         GError **error);

This calculates the XYZ from a CMF, illuminant and input spectrum.

`cmf` :	The color match function
`illuminant` :	The illuminant (you can use `cd_spectrum_new()` for type E)
`spectrum` :	The CdSpectrum input data
`value` :	The CdColorXYZ result
`resolution` :	The resolution in nm, typically 1.0
`error` :	A GError, or `NULL`
Returns :	`TRUE` if a XYZ value was set.

cd_it8_utils_calculate_cri_from_cmf ()

gboolean            cd_it8_utils_calculate_cri_from_cmf (CdIt8 *cmf,
                                                         CdIt8 *tcs,
                                                         CdSpectrum *illuminant,
                                                         gdouble *value,
                                                         gdouble resolution,
                                                         GError **error);

This calculates the CRI for a specific illuminant.

`cmf` :	The color match function
`tcs` :	The CIE TCS test patches
`illuminant` :	The illuminant
`value` :	The CRI result
`resolution` :	The resolution in nm, typically 1.0
`error` :	A GError, or `NULL`
Returns :	`TRUE` if a XYZ value was set.

cd_it8_utils_calculate_gamma ()

gboolean            cd_it8_utils_calculate_gamma        (CdIt8 *it8,
                                                         gdouble *gamma_y,
                                                         GError **error);

This estimates the gamma from values obtained from an .ti3 file.

`it8` :	The reference data
`gamma_y` :	The estimated gamma
`error` :	A GError, or `NULL`
Returns :	`TRUE` if a valid value was found.
