JNG(5)JNG(5)NAMEjng - JPEG Network Graphics (JNG) sub-format
DESCRIPTION
JNG (JPEG Network Graphics) is a sub-format of the MNG
(Multiple-image Network Graphics) format. As with MNG it
extends on the features of the popular PNG (Portable Net-
work Graphics) image-format.
This sub-format was designed to support a lossy compres-
sion-method. It is based completely on the JPEG specifi-
cation. It adds the high-compression ratios of JPEG for
photographic images.
As a member of the Network Graphics family, JNG was deemed
adequate as a stand-alone format as it extends the JPEG
format with color-correction and transparency features.
