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")

Todo list

  • Bezier curves
  • Lines
  • Testing
  • Add a bunch more shapes
  • Clean up the SVG renderer shapes
  • Draw anything other than a rectangle
  • Positions
  • Styles
  • Bitmap image output

Useful Commands

ffmpeg -framerate 60 -pattern_type glob -i '*.png' -c:v libx264 -pix_fmt yuv420p out. mp4

Convert PNG sequence to gif
