potrace - 1.16-2 main

potrace is a utility for tracing a bitmap, which means, transforming
a bitmap into a smooth, scalable image. The input is a bitmap (PBM, PGM,
PPM, or BMP format), and the default output is an encapsulated PostScript
file (EPS). A typical use is to create EPS files from scanned data, such as
company or university logos, handwritten notes, etc. The resulting image is
not "jaggy" like a bitmap, but smooth. It can then be rendered at any
resolution.
.
Potrace can currently produce the following output formats: EPS,
PostScript, PDF, SVG (scalable vector graphics), DXF, GeoJSON, PGM
(for easy antialiasing of pixel-based images), Gimppath, and
XFig. Additional backends might be added in the future.
