constructor

• new ColorState(): Gdk.ColorState

  Returns Gdk.ColorState

Static$gtype

Since 4.16create_cicp_params

• create_cicp_params(): Gdk.CicpParams

  Create a Gdk.CicpParams representing the colorstate.

  It is not guaranteed that every Gdk.ColorState can be represented with Cicp parameters. If that is the case, this function returns NULL.

  Returns Gdk.CicpParams

  A new Gdk.CicpParams

  Since

  4.16

Since 4.16equal

• equal(other: Gdk.ColorState): boolean

  Compares two GdkColorStates for equality.

  Note that this function is not guaranteed to be perfect and two objects describing the same color state may compare not equal. However, different color states will never compare equal.

  Parameters

  • other: Gdk.ColorState

    another GdkColorStatee

  Returns boolean

  true if the two color states compare equal

  Since

  4.16

Since 4.20equivalent

• equivalent(other: Gdk.ColorState): boolean

  Compares two GdkColorStates for equivalence.

  Two objects that represent the same color state should be equivalent, even though they may not be equal in the sense of Gdk.ColorState.equal.

  Parameters

  • other: Gdk.ColorState

    another GdkColorStatee

  Returns boolean

  true if the two color states are equivalent

  Since

  4.20

Since 4.16ref

• ref(): Gdk.ColorState

  Increase the reference count of self.

  Returns Gdk.ColorState

  the object that was passed in

  Since

  4.16

Since 4.16unref

• unref(): void

  Decrease the reference count of self.

  Unless self is static, it will be freed when the reference count reaches zero.

  Returns void

StaticSince 4.18get_oklab

• get_oklab(): Gdk.ColorState

  Returns the color state object representing the oklab color space.

  This is a perceptually uniform color state.

  Returns Gdk.ColorState

  Since

  4.18

StaticSince 4.18get_oklch

• get_oklch(): Gdk.ColorState

  Returns the color state object representing the oklch color space.

  This is the polar variant of oklab, in which the hue is encoded as a polar coordinate.

  Returns Gdk.ColorState

  Since

  4.18

StaticSince 4.16get_rec2100_linear

• get_rec2100_linear(): Gdk.ColorState

  Returns the color state object representing the linear rec2100 color space.

  This color state uses the primaries defined by BT.2020-2 and BT.2100-0 and a linear transfer function.

  It is equivalent to the Cicp tuple 9/8/0/1.

  See e.g. the CSS HDR Module for details about this colorstate.

  Returns Gdk.ColorState

  Since

  4.16

StaticSince 4.16get_rec2100_pq

• get_rec2100_pq(): Gdk.ColorState

  Returns the color state object representing the rec2100-pq color space.

  This color state uses the primaries defined by BT.2020-2 and BT.2100-0 and the transfer function defined by SMPTE ST 2084 and BT.2100-2.

  It is equivalent to the Cicp tuple 9/16/0/1.

  See e.g. the CSS HDR Module for details about this colorstate.

  Returns Gdk.ColorState

  Since

  4.16

StaticSince 4.16get_srgb

• get_srgb(): Gdk.ColorState

  Returns the color state object representing the sRGB color space.

  This color state uses the primaries defined by BT.709-6 and the transfer function defined by IEC 61966-2-1.

  It is equivalent to the Cicp tuple 1/13/0/1.

  See e.g. the CSS Color Module for details about this colorstate.

  Returns Gdk.ColorState

  Since

StaticSince 4.16get_srgb_linear

• get_srgb_linear(): Gdk.ColorState

  Returns the color state object representing the linearized sRGB color space.

  This color state uses the primaries defined by BT.709-6 and a linear transfer function.

  It is equivalent to the Cicp tuple 1/8/0/1.

  See e.g. the CSS Color Module for details about this colorstate.

  Returns Gdk.ColorState
