Author: openclaw

Trace bitmap images (PNG/JPG/WebP) into clean SVG paths using potrace/mkbitmap. Use to convert logos/silhouettes into vectors for downstream CAD workflows (e.g., create-dxf etch_svg_path) and for turning reference images into manufacturable outlines.

trace-to-svg

Convert a bitmap into a vector SVG using

mkbitmap

potrace

Quick start

# 1) Produce a silhouette-friendly SVG
bash scripts/trace_to_svg.sh input.png --out out.svg

# 2) Higher contrast + less noise
bash scripts/trace_to_svg.sh input.png --out out.svg --threshold 0.6 --turdsize 20

# 3) Feed into create-dxf (example)
# - set create-dxf drawing.etch_svg_paths[].d to the SVG path `d` you want, or
# - store the traced SVG and reference it in your pipeline.

Notes

This is best for logos, silhouettes, high-contrast shapes.
For photos or complex shading, results depend heavily on thresholding.
Output is usually one or more
```
<path>
```
elements.
