Struct BoxShadow 

pub struct BoxShadow {
    pub color: Color,
    pub offset: (f32, f32),
    pub blur: f32,
    pub spread: f32,
    pub blur_style: BlurStyle,
}

A soft drop shadow.

Fields

color: Color

Colour; its alpha sets the intensity.

offset: (f32, f32)

Offset (dx, dy), in logical pixels.

blur: f32

Blur radius.

spread: f32

How far the shadow grows beyond the box, before blurring.

blur_style: BlurStyle

Which side of the shadow’s edge the blur keeps (milestone 645): both, by default.

Implementations

impl BoxShadow

pub const fn new(dx: f32, dy: f32, blur: f32, color: Color) -> BoxShadow

A shadow offset by (dx, dy) with blur, and no spread.

pub const fn spread(self, spread: f32) -> BoxShadow

Sets the spread.

pub const fn blur_style(self, style: BlurStyle) -> BoxShadow

Sets which side of the edge the blur keeps: a solid shadow with a soft edge, a glow outside the box only, a shading inside it.

pub fn for_elevation(elevation: f32, color: Color) -> [BoxShadow; 3]

The three shadows a surface elevation high casts, in color: a sharp one close under it, a softer one further down, and a wide faint one all round. The reference’s own table, and its three strengths — a fifth, a seventh and an eighth of color’s opacity — so color is the shadow’s colour at full strength, black by default (milestone 606).

Between two heights of the table the shadows are interpolated, so a height that animates moves smoothly; past twenty-four, it is twenty-four.

pub fn bounds(&self, rect: Rect) -> Rect

The rectangle the shadow occupies around rect (offset + blur + spread).
