JNG(5)

NAME
jng - 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 Network Graphics) image-format.
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.
