Frequently asked questions

Why is the image small?

The default canvas is 300 × 300 pixels. For a larger figure, use the SVG output and scale it, or render at higher resolution with a local OpenBabel install.

Can I get a transparent background?

The PNG output has a white background. SVG output keeps a transparent background.
