Running the viewer without any arguments will render a built-in set of public-domain SVG images:

$ cargo run -p with_winit --release

Optionally, you can pass in paths to SVG files that you want to render:

$ cargo run -p with_winit --release -- [SVG FILES]


  • Mouse drag-and-drop will translate the image.
  • Mouse scroll wheel will zoom.
  • Arrow keys switch between SVG images in the current set.
  • Space resets the position and zoom of the image.
  • S toggles the frame statistics layer
  • C resets the min/max frame time tracked by statistics
  • D toggles displaying the required number of each kind of dynamically allocated element (default: off)
  • V toggles VSync on/off (default: on)
  • Escape exits the program.
