## Detailed Description

Gdk::CicpParams contains the parameters that define a colorstate according to the ITU-T H.273 specification.

See the documentation of individual properties for supported values.

The 'unspecified' value (2) is not treated in any special way, and must be replaced by a different value before creating a color state.

Gdk::CicpParams can be used as a builder object to construct a color state from Cicp data with build_color_state(). The function will throw an exception if the given parameters are not supported.

You can obtain a Gdk::CicpParams object from a color state with Gdk::ColorState::create_cicp_params(). This can be used to create a variant of a color state, by changing just one of the cicp parameters, or just to obtain information about the color state.

## ◆ build_color_state()

Glib::RefPtr< ColorState > Gdk::CicpParams::build_color_state | ( |  | ) | const

Creates a new `Gdk::ColorState` object for the cicp parameters in self.

Note that this may fail if the cicp parameters in self are not supported by GTK. In that case, `nullptr` is returned, and error is set with an error message that can be presented to the user.
