Enum BlendMode 

pub enum BlendMode {
    Normal,
    Multiply,
    Screen,
    Overlay,
    Darken,
    Lighten,
}

Compositing operator selected by blend_pixel / composite_into.

Variants

Normal

Standard Porter–Duff source-over (straight alpha).

Multiply

C = src * dst per colour channel (darkening filter).

Screen

C = 1 - (1 - src) * (1 - dst) (lightening filter).

Overlay

Per-channel: multiply when dst < 0.5, screen otherwise.

Darken

C = min(src, dst) per channel.

Lighten

C = max(src, dst) per channel.

Trait Implementations

impl Clone for BlendMode

fn clone(&self) -> BlendMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BlendMode

impl Debug for BlendMode

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

Formats the value using the given formatter.

impl Eq for BlendMode

impl Hash for BlendMode

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 BlendMode

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