Struct fdg_img::style::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) -> ShapeStyle

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) -> ShapeStyle

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:
