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

```rust // create a canvas to draw on let mut canvas = Canvas::new(100, 100);

// create a rectangle let mut rect = Drawing::new(Shape::Rectangle { width: 50, height: 50, });

// move it around rect.position.x = 25.0; rect.position.y = 25.0;

// give it a cool style rect.style = Style { fill: Some(Fill { color: RGB::new(0, 0, 0), }), stroke: Some(Stroke { width: 2, color: RGB::new(255, 0, 0), }), };

// add it to the canvas canvas.display_list.add(rect);

// save the canvas as an svg render::save( &canvas, "tests/svg/basicendto_end.svg", SvgRenderer::new(), ) .expect("Failed to save"); ```
