Class (GI Struct)

Gdk-4.0 ▶ Gdk ▶ ColorStateAbstractSince 4.16

Provides information to interpret colors and pixels in a variety of ways.

They are also known as color spaces.

Crucially, GTK knows how to convert colors from one color state to another.

Gdk.ColorState objects are immutable and therefore threadsafe.

$gtype: GType<ColorState>

Methods

  • 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

    Returns boolean

    true if the two color states compare equal

  • Decrease the reference count of self.

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

    Returns void

  • 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 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 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 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 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 ColorState
