Struct ColorCurve 

pub struct ColorCurve(pub KeyDataMap<Position, Color>);

A color-valued curve mapping Position → Color.

Used for multi-stop color gradients.

Tuple Fields

0: KeyDataMap<Position, Color>

Implementations

impl ColorCurve

pub fn black_to_white() -> Self

Create a black-to-white gradient.

pub fn evaluate(&self, position: f32) -> [f32; 4]

Evaluate the curve at a normalized position.

Trait Implementations

impl Clone for ColorCurve

fn clone(&self) -> ColorCurve

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DataTypeOps for ColorCurve

fn type_name(&self) -> &'static str

Returns a string name for this data type.

fn data_type(&self) -> DataType

Returns the DataType variant for this value.

impl Debug for ColorCurve

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

Formats the value using the given formatter.

impl Hash for ColorCurve

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 ColorCurve

fn eq(&self, other: &ColorCurve) -> 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 TryFrom<&Value> for ColorCurve

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: &Value) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Value> for ColorCurve

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: Value) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for ColorCurve

Available on crate feature curves only.
