Potrace is an open-source vectorizer (English tracer ), which converts raster to vector graphics. Potrace is developed by Peter Selinger and is dual- licensed: under the GPL and as Potrace Professional in a proprietary license of Selinger company Icosasoft software.
There are various graphical front-end for the command line program Potrace, it is for example in the free vector graphics editor Inkscape under the menu item Path - Trace Bitmap integrated. Even the free font editor FontForge can Potrace use to import bitmap graphics.
Potrace dominated many output formats, including PostScript, PDF and SVG.
The output of Potrace is black and white, color images are converted when reading to black and white images before they are vectorized. Nevertheless, Inkscape allows you to vectorize colored or grayscale images by each color channel is vectorized as a single black -and-white image of Potrace separately.
