Various graphical frontends are available for the command-line application Potrace. Notably, it has been integrated with
Inkscape, giving Inkscape its
Trace Bitmap action.
FontForge can use Potrace to import a bitmap image into a font. Potrace is also used by the
music engraving program
LilyPond. An open-source
progressive web app that uses Potrace is SVGcode. Potrace's input and output is black and white (colored images are
greyscaled 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 Vectorize program also uses Potrace as its core. Potrace is licensed under the
GNU General Public License v2.0 or later. A non-GPL version of Potrace called "Potrace Professional" is available under license from Selinger's company, Icosasoft Software, Inc. == Examples ==
