Enum gsk4::BlendMode

#[non_exhaustive]
pub enum BlendMode {
    Default,
    Multiply,
    Screen,
    Overlay,
    Darken,
    Lighten,
    ColorDodge,
    ColorBurn,
    HardLight,
    SoftLight,
    Difference,
    Exclusion,
    Color,
    Hue,
    Saturation,
    Luminosity,
}

The blend modes available for render nodes.

The implementation of each blend mode is deferred to the rendering pipeline.

See https://www.w3.org/TR/compositing-1/#blending for more information on blending and blend modes.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Default

The default blend mode, which specifies no blending

Multiply

The source color is multiplied by the destination and replaces the destination

Screen

Multiplies the complements of the destination and source color values, then complements the result.

Overlay

Multiplies or screens the colors, depending on the destination color value. This is the inverse of hard-list

Darken

Selects the darker of the destination and source colors

Lighten

Selects the lighter of the destination and source colors

ColorDodge

Brightens the destination color to reflect the source color

ColorBurn

Darkens the destination color to reflect the source color

HardLight

Multiplies or screens the colors, depending on the source color value

SoftLight

Darkens or lightens the colors, depending on the source color value

Difference

Subtracts the darker of the two constituent colors from the lighter color

Exclusion

Produces an effect similar to that of the difference mode but lower in contrast

Color

Creates a color with the hue and saturation of the source color and the luminosity of the destination color

Hue

Creates a color with the hue of the source color and the saturation and luminosity of the destination color

Saturation

Creates a color with the saturation of the source color and the hue and luminosity of the destination color

Luminosity

Creates a color with the luminosity of the source color and the hue and saturation of the destination color

Trait Implementations

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 From<BlendMode> for Value

fn from(v: BlendMode) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for BlendMode

type Checker = GenericValueTypeChecker<BlendMode>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl HasParamSpec for BlendMode

type ParamSpec = ParamSpecEnum

type SetValue = BlendMode

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str, _: BlendMode) -> ParamSpecEnumBuilder<'_, BlendMode>

fn param_spec_builder() -> Self::BuilderFn

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 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for BlendMode

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl StaticType for BlendMode

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for BlendMode

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl ValueType for BlendMode

type Type = BlendMode

Type to get the Type from.

impl Copy for BlendMode

impl Eq for BlendMode
