.SH DESCRIPTION
|
|
|
5 |
JNG (JPEG Network Graphics) is a sub-format of the MNG (Multiple-image
|
|
|
6 |
Network Graphics) format. As with MNG it extends on the features of the
|
|
|
7 |
popular PNG (Portable Network Graphics) image-format.

This sub-format was designed to support a lossy compression-method.
|
|
|
11 |
It is based completely on the JPEG specification. It adds the high-compression
|
|
|
12 |
ratios of JPEG for photographic images.
|
|
|

|
|
|
14 |
As a member of the Network Graphics family, JNG was deemed adequate as a
|
|
|
15 |
stand-alone format as it extends the JPEG format with color-correction and
|
|
|
16 |
transparency features.
