-.SH NAME
-png \- Portable Network Graphics (PNG) format
-.SH DESCRIPTION
-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, 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.
