POTRACE - transform bitmaps into vector graphics * * * DESCRIPTION Potrace is a tool for tracing a bitmap, which means, transforming a bitmap into a smooth, scalable image. The input is a bitmap (PBM, PGM, PPM, or BMP), and the default output is one of several vector file formats. 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. A separate program, mkbitmap, is also provided. This program can act as a pre-processor for Potrace, applying scaling and various filters to an image before converting it to a bitmap. This is useful for potracing greyscale and color images. DEPENDENCIES Potrace relies on the zlib library for PostScript level 3 compression. This library is pre-installed on most modern systems. If not present, it can be obtained from http://www.gzip.org/zlib/. COMPILATION For generic compilation instructions, see the file INSTALL. In addition, the following compile time options (options to ./configure) are supported. --with-libpotrace install Potrace library and headers (default: no) --disable-zlib disable PostScript level 3 compression --enable-metric use metric units (centimeters) as default --enable-a4 use a4 as the default papersize --enable-dumb-tty use simplified ASCII-only progress bar See also ./configure --help. INSTALLING If you are installing from sources, just do "make install" as root. If you are installing from a binary distribution, just copy the "potrace" and "mkbitmap" binaries to a place where the operating system expects them, such as /usr/local/bin. Also copy the files "potrace.1" and "mkbitmap.1" to a directory where the operating system looks for man pages, such as /usr/local/man/man1. For instructions on installing Potrace under Windows, see the file README-WIN USAGE For more detailed usage information, see the man page.

Default is inches (or pixels for pgm, dxf, and gimppath backends). Possible input file formats are: pnm (pbm, pgm, ppm), bmp. Backends are: eps, postscript, ps, pdf, pdfpage, svg, dxf, geojson, pgm, gimppath, xfig. POTRACE LIBRARY (FOR DEVELOPERS) As of Potrace release 1.6, the Potrace core functionality has been separated into a library libpotrace.a. This makes it easy to integrate tracing functionality into other GPL programs. The API of the library is defined in the header file potracelib.h, and is documented in doc/potracelib.pdf. It is not by default installed, but can be installed with the --with-libpotrace configuration option. DOCUMENTATION Usage information is contained in the man page: http://potrace.sourceforge.net/potrace.html Many common questions are answered in the FAQ: http://potrace.sourceforge.net/faq.html Some examples are given on the following web pages: http://potrace.sourceforge.net/samples.html http://potrace.sourceforge.net/mkbitmap.html The inner workings of the potrace algorithm are explained here: http://potrace.sourceforge.net/potrace.pdf The potrace library is documented here: http://potrace.sourceforge.net/potracelib.pdf COPYRIGHT Copyright (C) 2001-2015 Peter Selinger This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
