JNG
JNG (pronounced
jing) is a
JPEG-based image
file format,
closely related to
PNG.
The name stands for
JPEG Network Graphics.
Unlike
JFIF (the usual JPEG file format), JNG supports transparency.
JNG was created as an adjunct to the
MNG animation format
and is not a widely used as a stand-alone format.
The structure of JNG files is essentially the same as that of PNG files,
differing only in the slightly different signature
(8B 4A 4E 47 0D 0A 1A 0A in hexadecimal) and the use of different chunks.
JNG does not have a registered MIME media type,
but image/x-jng can be used.
