Edges
Trace
Outlines the threshold with real paths — and exports as vector.
Controls
- level
- Where the single closed outline is drawn between dark and light. Not a strength: there is always exactly one boundary
- smooth
- Simplifies the shape before it is traced. A boundary drawn on grain trembles at every pixel, and a plotter draws that tremble faithfully
- simplify
- How far a point may stray before it is dropped. Barely visible on screen; in the vector file it is hundreds of points instead of thousands
- width
- A number from 0.5 to 6 pixels, 1.5 by default.
- fill
- Fills what the outline encloses, turning a line into a silhouette — a stencil rather than a drawing
- contrast
- A number from -1 to 1, 0 by default.
- ink
- A colour, #111111 by default.
- paper
- A colour, #f5f2ea by default.
