# 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 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")
```
## Todo list
- [ ] Bezier curves
- [x] Lines
- [ ] Testing
- [ ] Add a bunch more shapes
- [ ] Clean up the SVG renderer shapes
- [x] Draw anything other than a rectangle
- [x] Positions
- [x] Styles
- [ ] Bitmap image output
## Useful Commands
### Convert PNG sequence to mp4

```
### Convert PNG sequence to gif
```
convert -delay 1 *.png output.gif
```
### Profiling
