Portable Network Graphics /ping/ (PNG) An extensible file format for the lossless, portable, well-compressed storage of raster images. PNG provides a patent-free replacement for GIF and can also replace many common uses of TIFF. Indexed-colour, greyscale and truecolour images are supported, plus an optional alpha channel. Sample depths range from 1 to 16 bits. PNG is designed for on-line 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 simple detection of common transmission errors. Also, PNG can store gamma correction and chromaticity data for improved colour matching on heterogeneous platforms. Filename extension: .png. RFC 2083. W3C PNG pages (http://www.w3.org/Graphics/PNG/). PNG home page (http://www.wco.com/~png/). (1997-08-07). Source: The Free On-line Dictionary of Computing.
