Enum OverlayFill 

pub enum OverlayFill {
    Solid([f32; 4]),
    LinearGradient {
        start_colour: [f32; 4],
        end_colour: [f32; 4],
        angle: f32,
    },
}

Fill style for an OverlayShapeItem.

Solid is the default and matches the previous single-colour behaviour. LinearGradient interpolates between two colours along an angled axis.

Variants

Solid([f32; 4])

Uniform solid colour in linear RGBA float format.

LinearGradient

Linear gradient between two colours.

The gradient runs along angle across the bounding box. angle = 0.0 goes left-to-right (start_colour on the left, end_colour on the right). Positive angles rotate the direction counter-clockwise in math coordinates; because screen Y points downward, angle = PI/2 produces a top-to-bottom gradient (start at top, end at bottom).

Fields

start_colour: [f32; 4]

RGBA colour at the start of the gradient (left when angle is 0).

end_colour: [f32; 4]

RGBA colour at the end of the gradient (right when angle is 0).

angle: f32

Gradient direction in radians. 0.0 = left-to-right.

Trait Implementations

impl Clone for OverlayFill

fn clone(&self) -> OverlayFill

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OverlayFill

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

Formats the value using the given formatter.

impl Default for OverlayFill

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for OverlayFill

fn eq(&self, other: &OverlayFill) -> 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 Copy for OverlayFill

impl StructuralPartialEq for OverlayFill
