.SH NAME

jng \- JPEG Network Graphics (JNG) sub-format

.SH 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 Network Graphics) image-format. 

.br

This sub-format was designed to support a lossy compression-method.

It is based completely on the JPEG specification. 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.
