draw
WARNING: This library is in early development! Expect changes.
A small Rust library for 2D drawing. Simple display list and vector shapes. Currently supports SVG output, designed to also support PNG and other formats.
Example
// create a canvas to draw on
let mut canvas = Canvas::new(100, 100);
// create a new drawing
let rect = Drawing::new()
// give it a shape
.with_shape(Shape::Rectangle {
width: 50,
height: 50,
})
// move it around
.with_xy(25.0, 25.0)
// give it a cool style
.with_style(Style::stroked(5, Color::black()));
// add it to the canvas
canvas.display_list.add(rect);
// save the canvas as an svg
render::save(
&canvas,
"tests/svg/basic_end_to_end.svg",
SvgRenderer::new(),
)
.expect("Failed to save")
