png.4(4) File Formats png.4(4)
NAME
png - Portable Network Graphics (PNG) format
DESCRIPTION
PNG (Portable Network Graphics) is an extensible file format for the lossless, portable, well-compressed storage of raster images. PNG pro-
vides a patent-free replacement for GIF and can also replace many common uses of TIFF. Indexed-color, grayscale, and truecolor images are
supported, and an optional alpha channel. Sample depths range from 1 to 16 bits.
PNG is designed to work well in online viewing applications, such as the World Wide Web, and is fully streamable with a progressive display
option. PNG is robust, and provides both full file integrity checking, and fast simple detection of common transmission errors. PNG can
store gamma and chromaticity data for improved color matching on heterogeneous platforms.
