class: CicpParamsMeta

[274:14] static extends: object

Generated metadata helpers for CicpParams class surfaces.

Methods

• properties ()

  Returns property metadata for CicpParams.

  • @r A list.

class: CicpParams

[25:7] extends: object

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. GdkCicpParams can be used as a builder object to construct a color state from Cicp data with [method@Gdk.CicpParams.build_color_state]. The function will return an error if the given parameters are not supported. You can obtain a GdkCicpParams object from a color state with [method@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.

Methods

• CicpParams ()

  Creates a new GdkCicpParams 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.

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.

• asObject ()

  Wraps this handle as Object.

  • @r A Object object.

• getProperty (string Name)

  Reads one generated property by name.

• setProperty (string Name, Value)

  Writes one generated property by name.

• setColorprimaries (int Value)

  The color primaries to use. Supported values: - 1: BT.709 / sRGB - 2: unspecified - 5: PAL - 6,7: BT.601 / NTSC - 9: BT.2020 - 12: Display P3

  • @p Value is the new property value.
  • @r None.

• setMatrixcoefficients (int Value)

  The matrix coefficients (for YUV to RGB conversion). Supported values: - 0: RGB - 1: BT.709 - 2: unspecified - 5,6: BT.601 - 9: BT.2020

  • @p Value is the new property value.
  • @r None.

• setRange (string Value)

  Whether the data is using the full range of values. The range of the data.

  • @p Value is the new property value.
  • @r None.

• setTransferfunction (int Value)

  The transfer function to use. Supported values: - 1,6,14,15: BT.709, BT.601, BT.2020 - 2: unspecified - 4: gamma 2.2 - 5: gamma 2.8 - 8: linear - 13: sRGB - 16: BT.2100 PQ - 18: BT.2100 HLG

  • @p Value is the new property value.
  • @r None.

• build_color_state ()

  Creates a new GdkColorState 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.

• get_color_primaries ()

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

• get_matrix_coefficients ()

  Gets the matrix-coefficients property of @self.

• get_range ()

  Gets the range property of @self.

• get_transfer_function ()

  Gets the transfer-function property of @self.

• set_color_primaries (int color_primaries)

  Sets the color-primaries property of @self.

  • @p color_primaries is the new color primaries value.
  • @r None.

• set_matrix_coefficients (int matrix_coefficients)

  • @self a GdkCicpParams Sets the matrix-coefficients property of @self.
  • @p matrix_coefficients is the new matrix-coefficients value.
  • @r None.

• set_range (string range)

  Sets the range property of @self

  • @p range is the range value.
  • @r None.

• set_transfer_function (int transfer_function)

  Sets the transfer-function property of @self.

  • @p transfer_function is the new transfer-function value.
  • @r None.
