Tracing

Edge sensitivity Line adjustment Min line length Smooth curves (Bézier) Centreline mode for thick strokes

Line adjustment and Smooth curves can also be set for one shape in its Style panel. Centreline mode thins filled strokes to their skeleton; best for high-contrast drawings. Turn it off to use edge detection. Sensitivity and length decide which shapes are found.

Universal style

Line colour Thickness 2.5 Fill shapes Fill opacity 35%

Colour applies to every line, replacing any individual line colours. Thickness and fill apply to every line except ones with their own Style.

Abstraction

Symmetry Copies 6 Spread 3 Layers 3 Layer size 70% Twist per layer 15° Simplification 3 Colour each layer Hide the traced drawing

Copies and Twist only apply to the radial styles. Every copy is an exact turn or mirror of the traced lines, so the equations stay exact. Changing a setting after generating updates the abstraction.

Click an equation to edit it (Enter to apply). Click a line on the graph to read its coordinates.
