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" +.BR "libpng"(3), " libpngpf"(3), " zlib"(3), " deflate"(5), " " and " zlib"(5) +.LP +PNG specification (second edition), November 2003: +.IP +.br +
