potrace binary package in Ubuntu Trusty amd64

 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.
