A blending mode.

Variants

Clear

Replaces destination with zero: fully transparent.

Source

Replaces destination.

Destination

Preserves destination.

SourceOver

Source over destination.

DestinationOver

Destination over source.

SourceIn

Source trimmed inside destination.

DestinationIn

Destination trimmed by source.

SourceOut

Source trimmed outside destination.

DestinationOut

Destination trimmed outside source.

SourceAtop

Source inside destination blended with destination.

DestinationAtop

Destination inside source blended with source.

Xor

Each of source and destination trimmed outside the other.

Plus

Sum of colors.

Modulate

Product of premultiplied colors; darkens destination.

Screen

Multiply inverse of pixels, inverting result; brightens destination.

Overlay

Multiply or screen, depending on destination.

Darken

Darker of source and destination.

Lighten

Lighter of source and destination.

ColorDodge

Brighten destination to reflect source.

ColorBurn

Darken destination to reflect source.

HardLight

Multiply or screen, depending on source.

SoftLight

Lighten or darken, depending on source.

Difference

Subtract darker from lighter with higher contrast.

Exclusion

Subtract darker from lighter with lower contrast.

Multiply

Multiply source with destination, darkening image.

Hue

Hue of source with saturation and luminosity of destination.

Saturation

Saturation of source with hue and luminosity of destination.

Color

Hue and saturation of source with luminosity of destination.

Luminosity

Luminosity of source with hue and saturation of destination.

Trait Implementations

impl Clone for BlendMode

fn clone(&self) -> BlendMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BlendMode

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

Formats the value using the given formatter.

impl Default for BlendMode

fn default() -> Self

Returns the “default value” for a type.

impl Ord for BlendMode

fn cmp(&self, other: &BlendMode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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.

impl PartialOrd for BlendMode

fn partial_cmp(&self, other: &BlendMode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
