PNG provides +a patent-free replacement for GIF and can also replace many +common uses of TIFF. Indexed-color, grayscale, and truecolor images are +supported, plus an optional alpha channel. Sample depths range from +1 to 16 bits. +.br + +PNG is designed to work well in online viewing applications, such as the +World Wide Web, so it is fully streamable with a progressive display +option. PNG is robust, providing both full file integrity checking and +fast, simple detection of common transmission errors. Also, PNG can store +gamma and chromaticity data for improved color matching on heterogeneous +platforms. + +.SH "SEE ALSO" +.IR libpng(3), zlib(3), deflate(5), and zlib(5) +.LP +PNG specification (second edition), November 2003: +.IP +.br + <http://www.w3.org/TR/2003/REC-PNG-20031110/ +PNG 1.2 specification, July 1999: +.IP +.br +http://www.libpng.org/pub/png +.LP +PNG 1.0 specification, October 1996: +.IP +.br +RFC 2083 +.IP +.br +ftp://ds.internic.net/rfc/rfc2083.txt +.br +or (as a W3C Recommendation) at +.br +http://www.w3.org/TR/REC-png.html +.SH AUTHORS +This man page: Glenn Randers-Pehrson +.LP +Portable Network Graphics (PNG) Specification (Second Edition) +Information technology - Computer graphics and image processing - +Portable Network Graphics (PNG): Functional specification. +ISO/IEC 15948:2003 (E) (November 10, 2003): David Duce and others. +.LP +Portable Network Graphics (PNG) Specification Version 1.2 (July 8, 1999): +Glenn Randers-Pehrson and others (png-list). +.LP +Portable Network Graphics (PNG) Specification Version 1.0 (October 1, 1996): +Thomas Boutell and others (png-list). +.LP + + +.SH COPYRIGHT NOTICE +.LP +This man page is Copyright (c) 1998-2006 Glenn Randers-Pehrson.
