class Gdk::CicpParams

Overview

Contains the parameters that define a colorstate with cicp parameters.

Cicp parameters are specified in 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 Gdk::CicpParams#build_color_state. The function will return an error 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.

Constructor Detail

def self.new : self #

Creates a new Gdk::CicpParams object.

The initial values of the properties are the values for "undefined" and need to be set before a color state object can be built.


def self.new(*, color_primaries : UInt32 | Nil = nil, matrix_coefficients : UInt32 | Nil = nil, range : Gdk::CicpRange | Nil = nil, transfer_function : UInt32 | Nil = nil) #

Class Method Detail

def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.


Instance Method Detail

def ==(other : self) #
Description copied from class Reference

Returns true if this reference is the same as other. Invokes same?.


def build_color_state : Gdk::ColorState #

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, NULL is returned, and error is set with an error message that can be presented to the user.


def color_primaries : UInt32 #

Returns the value of the color-primaries property of self.


def color_primaries=(color_primaries : UInt32) : Nil #

Sets the color-primaries property of self.


def hash(hasher) #
Description copied from class Reference

See Object#hash(hasher)


def matrix_coefficients : UInt32 #

Gets the matrix-coefficients property of self.


def matrix_coefficients=(matrix_coefficients : UInt32) : Nil #

@self a Gdk::CicpParams Sets the matrix-coefficients property of self.


def range : Gdk::CicpRange #

Gets the range property of self.


def range=(range : Gdk::CicpRange) : Nil #

Sets the range property of self


def transfer_function : UInt32 #

Gets the transfer-function property of self.


def transfer_function=(transfer_function : UInt32) : Nil #

Sets the transfer-function property of self.
