Enum printpdf::types::plugins::graphics::extgstate::BlackGenerationFunction

pub enum BlackGenerationFunction {
    Default,
    WithUnderColorRemoval,
}

Black generation calculates the amount of black to be used when trying to reproduce a particular color.

Variants

Default

Regular black generation function

let cyan = 1.0 - red;
let magenta = 1.0 - green;
let yellow = 1.0 - blue;
let black = min(cyan, magenta, yellow);

WithUnderColorRemoval

Expects an UnderColorRemoval to be set. This will compensate the color for the added black

let cyan = 1.0 - red;
let magenta = 1.0 - green;
let yellow = 1.0 - blue;
let black = min(cyan, magenta, yellow);
