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.
