Enum printpdf::UnderColorRemovalFunction

pub enum UnderColorRemovalFunction {
    Default,
}

See BlackGenerationFunction, too. Undercolor removal reduces the amounts of the cyan, magenta, and yellow components to compensate for the amount of black that was added by black generation.

The undercolor-removal function computes the amount to subtract from each of the intermediate c, m, and y values to produce the final cyan, magenta, and yellow components. It can simply return its k operand unchanged, or it can return 0.0 (so that no color is removed), some fraction of the black amount, or even a negative amount, thereby adding to the total amount of colorant.

Trait Implementations

impl Clone for UnderColorRemovalFunction

fn clone(&self) -> UnderColorRemovalFunction

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UnderColorRemovalFunction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for UnderColorRemovalFunction

fn eq(&self, other: &UnderColorRemovalFunction) -> 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.
