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), Xfig, Gimppath, and PGM
(for easy antialiasing).
Mkbitmap is a program distributed with Potrace which can be used to pre-
process the input for better tracing behavior on greyscale and color
images.
