Implementations

impl OrgKdeKwinContrast

pub fn commit(&self)

pub fn set_region(&self, region: Option<&WlRegion>)

pub fn set_contrast(&self, contrast: f64)

pub fn set_intensity(&self, intensity: f64)

pub fn set_saturation(&self, saturation: f64)

pub fn release(&self)

release the contrast object

pub fn set_frost(&self, red: i32, green: i32, blue: i32, alpha: i32)

opt into frost effect w/ given colour

enables ‘frost’ variant of contrast effect.

‘frost’ is an enhanced version of the contrast effect that uses different colour arithmetic to get backgrounds simultaneously higher in contrast and (apparent) transparency.

r, g, b, a are channels from 0-255, indicating a colour to use in contrast calculation. should be based off of the “main” background colour of the surface.

pub fn unset_frost(&self)

opts out of frost effect

impl PartialEq<Weak<OrgKdeKwinContrast>> for OrgKdeKwinContrast

fn eq(&self, other: &Weak<OrgKdeKwinContrast>) -> 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.
