Enum ScreenType 

pub enum ScreenType {
    Dispersed,
    Clustered,
    StochasticClustered,
}

Halftone screen type used by ScreenParams.

Extension policy

Not #[non_exhaustive]: the screen-building code uses exhaustive match; the compiler ensures new screen types are handled everywhere.

Variants

Dispersed

Bayer-style dispersed-dot ordered dither.

Chosen automatically below 300 dpi (4 × 4 matrix). The default.

Clustered

Clustered-dot halftone screen.

StochasticClustered

Stochastic clustered-dot screen (64 × 64 matrix, used ≥ 300 dpi).

Trait Implementations

impl Clone for ScreenType

fn clone(&self) -> ScreenType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScreenType

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

Formats the value using the given formatter.

impl Default for ScreenType

fn default() -> ScreenType

Returns the “default value” for a type.

impl Hash for ScreenType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ScreenType

fn eq(&self, other: &ScreenType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
