-.SH "DESCRIPTION"
-.PP
-PNG (Portable Network Graphics) is 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-color, grayscale, and truecolor images are supported, and an
-optional alpha channel\&. Sample depths range from 1 to 16 bits\&.
-.PP
-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\&.
