Potrace is an open-source, cross-platform computer program which converts bitmapped images into vector graphics. It is written and maintained by Peter Selinger.
Various frontends are available for Potrace. Notably, it has been integrated with Inkscape, giving Inkscape its Trace Bitmap action.[2] CR8tracer is a simple Windows GUI based frontend. FontForge can use Potrace to import a bitmap image into a font. Potrace is also used by the music engraving program LilyPond.
Potrace's input and output is black and white (colored images are converted to bitmap before processing). However, Inkscape is capable of producing color images by decomposing each channel into several black and white images and tracing them separately with Potrace. The commercial Total Vectorise program also uses Potrace as its core.
Potrace is dual-licensed under the GPL and a proprietary license by Selinger's company, Icosasoft Software, Inc.[3]
