.SH DESCRIPTION |
|
5 |
PNG (Portable Network Graphics) is an extensible file format for the |
|
6 |
lossless, portable, well-compressed storage of raster images. PNG provides |
|
7 |
a patent-free replacement for GIF and can also replace many |
|
8 |
common uses of TIFF. Indexed-color, grayscale, and truecolor images are |
|
9 |
supported, plus an optional alpha channel. Sample depths range from |
|
10 |
1 to 16 bits. |
|

PNG is designed to work well in online viewing applications, such as the |
|
14 |
World Wide Web, so it is fully streamable with a progressive display |
|
15 |
option. PNG is robust, providing both full file integrity checking and |
|
16 |
fast, simple detection of common transmission errors. Also, PNG can store |
|
17 |
gamma and chromaticity data for improved color matching on heterogeneous |
|
18 |
platforms. |
