Struct tiny_skia::LinearGradient

pub struct LinearGradient { /* private fields */ }

A linear gradient shader.

Implementations

impl LinearGradient

pub fn new( start: Point, end: Point, stops: Vec<GradientStop>, mode: SpreadMode, transform: Transform ) -> Option<Shader<'static>>

Creates a new linear gradient shader.

Returns Shader::SolidColor when:

• stops.len() == 1
• start and end are very close

Returns None when:

• stops is empty
• start == end
• transform is not invertible

Trait Implementations

impl Clone for LinearGradient

fn clone(&self) -> LinearGradient

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LinearGradient

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

Formats the value using the given formatter.

impl PartialEq for LinearGradient

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