Struct ShapeStyle

pub struct ShapeStyle {
    pub color: RGBAColor,
    pub filled: bool,
    pub stroke_width: u32,
}

Style for any shape

Fields

color: RGBAColor

Specification of the color.

filled: bool

Whether the style is filled with color.

stroke_width: u32

Stroke width.

Implementations

impl ShapeStyle

pub fn filled(&self) -> Self

Returns a filled style with the same color and stroke width.

Example

use plotters::prelude::*;
let original_style = ShapeStyle {
    color: BLUE.mix(0.6),
    filled: false,
    stroke_width: 2,
};
let filled_style = original_style.filled();
let drawing_area = SVGBackend::new("shape_style_filled.svg", (400, 200)).into_drawing_area();
drawing_area.fill(&WHITE).unwrap();
drawing_area.draw(&Circle::new((150, 100), 90, original_style));
drawing_area.draw(&Circle::new((250, 100), 90, filled_style));

The result is a figure with two circles, one of them filled:

pub fn stroke_width(&self, width: u32) -> Self

Returns a new style with the same color and the specified stroke width.

Example

use plotters::prelude::*;
let original_style = ShapeStyle {
    color: BLUE.mix(0.6),
    filled: false,
    stroke_width: 2,
};
let new_style = original_style.stroke_width(5);
let drawing_area = SVGBackend::new("shape_style_stroke_width.svg", (400, 200)).into_drawing_area();
drawing_area.fill(&WHITE).unwrap();
drawing_area.draw(&Circle::new((150, 100), 90, original_style));
drawing_area.draw(&Circle::new((250, 100), 90, new_style));

The result is a figure with two circles, one of them thicker than the other:

Trait Implementations

impl BackendStyle for ShapeStyle

fn color(&self) -> BackendColor

Returns the color as interpreted by the backend.

fn stroke_width(&self) -> u32

Returns the stroke width.

impl Clone for ShapeStyle

fn clone(&self) -> ShapeStyle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ShapeStyle

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

Formats the value using the given formatter.

impl<T: Color> From<T> for ShapeStyle

fn from(f: T) -> Self

Converts to this type from the input type.

impl PartialEq for ShapeStyle

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

impl StructuralPartialEq for ShapeStyle

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
