ColorState

Added in version 4.16.

class ColorState(*args, **kwargs)

A GdkColorState object provides the 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.

GdkColorState objects are immutable and therefore threadsafe.

Methods

class ColorState

create_cicp_params() → CicpParams | None

Create a 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.

Added in version 4.16.

equal(other: ColorState) → bool

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.

Added in version 4.16.

Parameters:

other – another GdkColorStatee

classmethod get_rec2100_linear() → 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.

Added in version 4.16.

classmethod get_rec2100_pq() → 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.

Added in version 4.16.

classmethod get_srgb() → 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.

Added in version 4.16.

classmethod get_srgb_linear() → 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.

Added in version 4.16.
