Description

Functions to do unusual things with profiles.

Functions

cd_icc_utils_get_coverage ()

gboolean
cd_icc_utils_get_coverage (CdIcc *icc,
                           CdIcc *icc_reference,
                           gdouble *coverage,
                           GError **error);

Gets the gamut coverage of two profiles where 0.5 would mean the gamut is half the size, and 2.0 would indicate the gamut is twice the size.

Parameters

icc	The profile to test
icc_reference	The reference profile, e.g. sRGB
coverage	The coverage of `icc` on `icc_reference`
error	A GError, or `NULL`

Returns

TRUE for success

cd_icc_utils_get_adaptation_matrix ()

gboolean
cd_icc_utils_get_adaptation_matrix (CdIcc *icc,
                                    CdIcc *icc_reference,
                                    CdMat3x3 *out,
                                    GError **error);

Computes a correction matrix suitable for adjusting colors in a reference color space icc_reference (typically sRGB) to the color space of a target device described by icc .

This function is designed to be used by desktop window systems to program the color transform matrix (CTM) property of the display hardware.

Parameters

icc	The measured ICC profile for the target device.
icc_reference	The ICC profile to use as a reference (typically sRGB).
mat	The returned adaptation matrix.	[out]
error	A GError, or `NULL`.	[out]

Returns

TRUE for success
