Enum slint::Brush

#[non_exhaustive]
pub enum Brush {
    SolidColor(Color),
    LinearGradient(LinearGradientBrush),
    RadialGradient(RadialGradientBrush),
}
Expand description

A brush is a data structure that is used to describe how a shape, such as a rectangle, path or even text, shall be filled. A brush can also be applied to the outline of a shape, that means the fill of the outline itself.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

SolidColor(Color)

The color variant of brush is a plain color that is to be used for the fill.

§

LinearGradient(LinearGradientBrush)

The linear gradient variant of a brush describes the gradient stops for a fill where all color stops are along a line that’s rotated by the specified angle.

§

RadialGradient(RadialGradientBrush)

The radial gradient variant of a brush describes a circle variant centered in the middle

Implementations§

§

impl Brush

pub fn color(&self) -> Color

If the brush is SolidColor, the contained color is returned. If the brush is a LinearGradient, the color of the first stop is returned.

pub fn is_transparent(&self) -> bool

Returns true if this brush contains a fully transparent color (alpha value is zero)

assert!(Brush::default().is_transparent());
assert!(Brush::SolidColor(Color::from_argb_u8(0, 255, 128, 140)).is_transparent());
assert!(!Brush::SolidColor(Color::from_argb_u8(25, 128, 140, 210)).is_transparent());

pub fn is_opaque(&self) -> bool

Returns true if this brush is fully opaque

assert!(!Brush::default().is_opaque());
assert!(!Brush::SolidColor(Color::from_argb_u8(25, 255, 128, 140)).is_opaque());
assert!(Brush::SolidColor(Color::from_rgb_u8(128, 140, 210)).is_opaque());

pub fn brighter(&self, factor: f32) -> Brush

Returns a new version of this brush that has the brightness increased by the specified factor. This is done by calling Color::brighter on all the colors of this brush.

pub fn darker(&self, factor: f32) -> Brush

Returns a new version of this brush that has the brightness decreased by the specified factor. This is done by calling Color::darker on all the color of this brush.
