Struct epaint::shadow::Shadow

source ·
pub struct Shadow {
    pub offset: Vec2,
    pub blur: f32,
    pub spread: f32,
    pub color: Color32,
}
Expand description

The color and fuzziness of a fuzzy shape.

Can be used for a rectangular shadow with a soft penumbra.

Very similar to a box-shadow in CSS.

Fields§

§offset: Vec2

Move the shadow by this much.

For instance, a value of [1.0, 2.0] will move the shadow 1 point to the right and 2 points down, causing a drop-shadow effect.

§blur: f32

The width of the blur, i.e. the width of the fuzzy penumbra.

A value of 0.0 means a sharp shadow.

§spread: f32

Expand the shadow in all directions by this much.

§color: Color32

Color of the opaque center of the shadow.

Implementations§

source§

impl Shadow

source

pub const NONE: Self = _

No shadow at all.

source

pub fn as_shape(&self, rect: Rect, rounding: impl Into<Rounding>) -> RectShape

The argument is the rectangle of the shadow caster.

source

pub fn margin(&self) -> Margin

How much larger than the parent rect are we in each direction?
