vtracer

Unlike Potrace, VTracer handles colored high-resolution scans without binarization, making it suitable for photographs and complex graphics.

Uses a stacking strategy to produce fewer shapes and avoid shapes with holes, resulting in more efficient vector files compared to Adobe Illustrator's Image Trace.

Employs an O(n) tracing algorithm, which is more efficient than Potrace's O(n²) fitting algorithm, especially for large images like gigapixel scans.

Available as a command-line tool, Rust library, Python library, and web application, offering flexibility for various development environments and use cases.
