Enum ColourFilter 

pub enum ColourFilter {
    None,
    Grayscale,
    Inverted,
    GrayscaleInverted,
}
Expand description

A whole-screen colour transform, as the compositor applies it.

Variants§

§

None

The screen as it is.

§

Grayscale

Hue and saturation removed, luminosity kept.

§

Inverted

Every channel inverted.

§

GrayscaleInverted

Grey, then inverted.

Implementations§

§

impl ColourFilter

pub fn paint(self, scene: &mut Scene, transform: Affine, rect: Rect)

Apply the filter to what scene drew under rect so far: the blend the compositor uses for the whole screen, here for one area.
