# Potrace Automated Bitmap-to-Vector SVG Tracer

Traces monochrome raster images using Potrace / potrace-js: thresholding, turnpolicy heuristics, curve smoothing, alphamax corner optimization, and SVG path extraction.

## When to Invoke
Invoke this skill whenever you need to:
- trace bitmap to svg potrace
- convert scanned signature to vector svg
- smooth bitmap edges potrace

## Execution SOP & Rules
1. Pre-process input images to high contrast grayscale or black-and-white for optimal tracing.
2. Configure threshold options: { threshold: 128, turnpolicy: 'majority' } to balance detail vs smoothness.
3. Tune optcurve: true and alphamax: 1.0 to eliminate jagged pixelated artifacts on curves.
4. Sanitize and format output SVG path strings before embedding in web interfaces.

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
