geo-svg

This crate is a lib to generate SVG strings from geo-types.

Below is an example of a geometry collection rendered to SVG.

Features

• GeometryCollection and all variants of Geometry are supported
• the viewport size is automatically computed to contain all shapes
• style and formatting options are available
• the image size can be set in absolute units such as cm or px.

Example

The following will show how to convert a line to a SVG string. The to_svg method is provided by the ToSvg trait which is implemented for all geo-types.

use geo_types::{Coordinate, Line, Point};
use geo_svg::{Color, ToSvg};
let point = Point::new(10.0, 28.1);
let line = Line::new(
    Coordinate { x: 114.19, y: 22.26 },
    Coordinate { x: 15.93, y: -15.76 },
);

let svg = point
    .to_svg()
    .with_radius(2.0)
    .and(line.to_svg().with_stroke_width(2.5))
    .with_fill_color(Color::Named("red"))
    .with_stroke_color(Color::Rgb(200, 0, 100))
    .with_fill_opacity(0.7);

println!("{}", svg);

Result
