- 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>
-
- <p> 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.
