Struct wayland_protocols_wlr::gamma_control::v1::client::zwlr_gamma_control_v1::ZwlrGammaControlV1

pub struct ZwlrGammaControlV1 {
    id: ObjectId,
    version: u32,
    data: Option<Arc<dyn ObjectData>>,
    backend: WeakBackend,
}

adjust gamma tables for an output

This interface allows a client to adjust gamma tables for a particular output.

The client will receive the gamma size, and will then be able to set gamma tables. At any time the compositor can send a failed event indicating that this object is no longer valid.

There can only be at most one gamma control object per output, which has exclusive access to this particular output. When the gamma control object is destroyed, the gamma table is restored to its original value.

See also the Event enum for this interface.

Fields

id: ObjectId

version: u32

data: Option<Arc<dyn ObjectData>>

backend: WeakBackend

Implementations

impl ZwlrGammaControlV1

pub fn set_gamma(&self, fd: BorrowedFd<'_>)

set the gamma table

Set the gamma table. The file descriptor can be memory-mapped to provide the raw gamma table, which contains successive gamma ramps for the red, green and blue channels. Each gamma ramp is an array of 16-byte unsigned integers which has the same length as the gamma size.

The file descriptor data must have the same length as three times the gamma size.

pub fn destroy(&self)

destroy this control

Destroys the gamma control object. If the object is still valid, this restores the original gamma tables.

impl PartialEq<Weak<ZwlrGammaControlV1>> for ZwlrGammaControlV1

fn eq(&self, other: &Weak<ZwlrGammaControlV1>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
