Svg

The Svg widget is able to display an SVG image. It has two methods of constructions. We can set how to fit the image content into the widget bounds.

To use the widget, we have to enable the svg feature. The Cargo.toml dependencies should look like this:

[dependencies]
iced = { version = "0.13.1", features = ["svg"] }

Let's add an SVG image named pic.svg into the project root directory, i.e., the image has the path my_project/pic.svg where my_project is the name of our project. The file pic.svg contains the following content:

<svg viewBox="0 0 400 300" xmlns="http://www.w3.org/2000/svg">
    <rect width="400" height="300" style="fill:rgb(100,130,160)"/>
    <circle cx="200" cy="150" r="100" style="fill:rgb(180,210,240)"/>
</svg>

Our example is as follows:

use iced::{
    widget::{column, svg, svg::Handle, text, Svg},
    ContentFit, Element,
};

fn main() -> iced::Result {
    iced::run("svg", MyApp::update, MyApp::view)
}

struct MyApp {
    _state: String,
} 

impl Default for MyApp {
    fn default() -> Self {
        MyApp::new()
    }
}

#[derive(Debug, Clone)]
enum Message {
    _Message1,
}

impl MyApp {
    fn new() -> Self {
        Self {
            _state: String::new(),
        }
    }

    fn update(&mut self, _message: Message) {
        todo!()
    }

    fn view(&self) -> Element<Message> {
        column!(
            text("Construct from struct"),
            Svg::from_path("pic.svg"),
            text("Construct from function"),
            svg(Handle::from_path("pic.svg")),
            text("Different content fit"),
           svg(Handle::from_path("pic.svg")).content_fit(ContentFit::None),
        )
        .into()
    }
}
