Enum ColorTransform 

pub enum ColorTransform {
    Dim(f32),
    Lighten(f32),
    Opacity(f32),
    OpacityToward {
        factor: f32,
        target: Color,
    },
    Tint(Color, f32),
}

A relative transform applied to an already-resolved color.

Variants

Dim(f32)

Dim toward black by an amount in [0.0, 1.0].

Lighten(f32)

Lighten toward white by an amount in [0.0, 1.0].

Opacity(f32)

Blend toward the resolved background by alpha (1.0 - opacity).

1.0 keeps the original color unchanged, while 0.0 fully washes it into the current background. This is most useful for foreground colors on both dark and light themes.

OpacityToward

Like Self::Opacity, but blend toward a fixed target instead of the cell backdrop.

Fields

factor: f32

Same semantics as Self::Opacity: 1.0 is unchanged, 0.0 is fully target.

target: Color

Destination color when factor approaches 0.0.

Tint(Color, f32)

Blend toward color by alpha in [0.0, 1.0].

Implementations

impl ColorTransform

pub fn apply(self, color: Color) -> Color

Apply this transform to color.

pub fn apply_with_backdrop(self, color: Color, backdrop: Option<Color>) -> Color

Apply this transform to color, optionally using a resolved backdrop.

pub fn apply_paint(self, paint: Paint) -> Paint

Apply this transform to paint.

Pigment transforms preserve the paint alpha; Self::Opacity composes with the existing alpha by multiplying it by the opacity factor.

pub fn apply_paint_with_backdrop( self, paint: Paint, backdrop: Option<Paint>, ) -> Paint

Apply this transform to paint, optionally using a resolved backdrop paint.

Trait Implementations

impl Clone for ColorTransform

fn clone(&self) -> ColorTransform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ColorTransform

impl Debug for ColorTransform

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ColorTransform

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ColorTransform

impl Hash for ColorTransform

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 ColorTransform

fn eq(&self, other: &Self) -> 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 Serialize for ColorTransform

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
