Struct GradientPaint 

pub struct GradientPaint {
    pub angle_deg: f64,
    pub stops: Vec<GradientStop>,
    pub radial: bool,
    pub center_x: Option<f64>,
    pub center_y: Option<f64>,
    pub radius_frac: Option<f64>,
}

A gradient fill paint — either linear (default) or radial.

For linear gradients, angle_deg controls the gradient line. For radial gradients, radial=true is set and center_x/center_y/radius_frac control the radial geometry (all as fractions of the bounding box).

The radial field and the three radial-geometry fields are omitted from JSON when they hold their zero/none defaults, so existing linear GradientPaint values serialize byte-identically.

Fields

angle_deg: f64

Gradient-line angle in degrees, clockwise from +x. Ignored for radial.

stops: Vec<GradientStop>

Ordered color stops (at least two).

radial: bool

true when this is a radial gradient. Omitted (default false) for linear.

center_x: Option<f64>

Radial center X as a fraction of bounding-box width. None → 0.5.

center_y: Option<f64>

Radial center Y as a fraction of bounding-box height. None → 0.5.

radius_frac: Option<f64>

Radial radius as a fraction of hypot(w, h) / 2. None → 1.0.

Trait Implementations

impl Clone for GradientPaint

fn clone(&self) -> GradientPaint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GradientPaint

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

Formats the value using the given formatter.

impl PartialEq for GradientPaint

fn eq(&self, other: &GradientPaint) -> 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 GradientPaint

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
