PointerInterface
public class ColorState extends Record
Provides information to interpret colors and pixels in a variety of ways.

They are also known as
[*color spaces*](https://en.wikipedia.org/wiki/Color_space).

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

`GdkColorState` objects are immutable and therefore threadsafe.

  • Konstruktordetails

  • Methodendetails

    • getClassHandler

      public static ClassHandler getClassHandler()

    • createCicpParams

      public CicpParams createCicpParams()
      Create a [class@Gdk.CicpParams] representing the colorstate.

      It is not guaranteed that every `GdkColorState` can be
      represented with Cicp parameters. If that is the case,
      this function returns `NULL`.
      Gibt zurück:
      A new [class@Gdk.CicpParams]

    • equal

      public boolean equal(@Nonnull ColorState other)
      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.
      Parameter:
      other - another `GdkColorStatee`
      Gibt zurück:
      %TRUE if the two color states compare equal

    • ref

      public ColorState ref()
      Increase the reference count of @self.
      Gibt zurück:
      the object that was passed in

    • unref

      public void unref()
      Decrease the reference count of @self.

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

    • getOklab

      public static ColorState getOklab()
      Returns the color state object representing the oklab color space.

      This is a perceptually uniform color state.
      Gibt zurück:
      the color state object for oklab

    • getOklch

      public static ColorState getOklch()
      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.
      Gibt zurück:
      the color state object for oklch

    • getRec2100Linear

      public static ColorState getRec2100Linear()
      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](class.CicpParams.html) tuple 9/8/0/1.

      See e.g. [the CSS HDR Module](https://drafts.csswg.org/css-color-hdr/#valdef-color-rec2100-linear)
      for details about this colorstate.
      Gibt zurück:
      the color state object for linearized rec2100

    • getRec2100Pq

      public static ColorState getRec2100Pq()
      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](class.CicpParams.html) tuple 9/16/0/1.

      See e.g. [the CSS HDR Module](https://drafts.csswg.org/css-color-hdr/#valdef-color-rec2100-pq)
      for details about this colorstate.
      Gibt zurück:
      the color state object for rec2100-pq

    • getSrgb

      public static ColorState getSrgb()
      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](class.CicpParams.html) tuple 1/13/0/1.

      See e.g. [the CSS Color Module](https://www.w3.org/TR/css-color-4/#predefined-sRGB)
      for details about this colorstate.
      Gibt zurück:
      the color state object for sRGB

    • getSrgbLinear

      public static ColorState getSrgbLinear()
      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](class.CicpParams.html) tuple 1/8/0/1.

      See e.g. [the CSS Color Module](https://www.w3.org/TR/css-color-4/#predefined-sRGB-linear)
      for details about this colorstate.
      Gibt zurück:
      the color state object for linearized sRGB
