VTracer is an open-source software designed to convert raster images into vector graphics. Unlike Potrace which only accepts binarized inputs, VTracer can handle colored high-resolution scans. The software uses a stacking strategy to avoid producing shapes with holes, resulting in more compact output compared to Adobe Illustrator’s Image Trace. VTracer was originally created for processing high-resolution scans of historic blueprints, but it can also handle low-resolution pixel art. The software is implemented in Rust and offers a web application as well as a command-line app. The author mentions future plans for path simplification, perfect cut-out mode, pencil tracing, and image cleaning.
