}

Defines how new pixels are composited with existing pixels on the canvas.

Maps directly to the CSS globalCompositeOperation property.

Variants

Normal

The source is drawn over the destination (default alpha blending).

Multiply

The source color is multiplied with the destination, producing a darker result.

Screen

The source and destination are inverted, multiplied, then inverted again.

Lighter

The source and destination colors are added together, clamped to maximum brightness.

Overlay

Combines Multiply and Screen based on the destination color.

Darken

Keeps the darker of the source and destination per channel.

Lighten

Keeps the lighter of the source and destination per channel.

ColorDodge

Dodges the destination color brightening it based on the source.

ColorBurn

Burns the destination color darkening it based on the source.

HardLight

A harsher version of Overlay using the source color as the filter.

SoftLight

A softer version of Overlay using the source color as the filter.

Difference

Subtracts the darker color from the lighter color per channel.

Exclusion

Similar to Difference but with lower contrast.

Hue

Uses the hue of the source with the saturation and luminosity of the destination.

Saturation

Uses the saturation of the source with the hue and luminosity of the destination.

Color

Uses the hue and saturation of the source with the luminosity of the destination.

Luminosity

Uses the luminosity of the source with the hue and saturation of the destination.

Implementations

impl BlendMode

Implements CSS composite operation string conversion for BlendMode.

pub fn to_css_string(&self) -> &str

Returns the CSS globalCompositeOperation string for this blend mode.

Returns

• &str - The CSS composite operation string.

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 Default for BlendMode

fn default() -> BlendMode

Returns the “default value” for a type.

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.
