Trait rgb::ComponentMap

source · [−]

    fn map<Callback>(&self, f: Callback) -> DestPixel
    where
        Callback: FnMut(SrcComponent) -> DestComponent;

Expand description

Applying operation to every component

use rgb::ComponentMap;
let inverted = pixel.map(|c| 255 - c);

// For simple math there are Add/Sub/Mul implementations:
let halved = pixel.map(|c| c / 2);
let doubled = pixel * 2;

Required Methods

Convenience function (equivalent of self.iter().map().collect()) for applying the same formula to every component.

Note that it returns the pixel directly, not an Interator.
