This is a datatype for JNG pictures.  JNG is a format based on
JPEG, primarily used within MNG animations.

This datatype uses libmng (www.libmng.com).  As a side-effect
it also supports MNG (first frame only) and PNG (although I
doubt there are any advantages over the OS4 standard one)

INSTALLATION
============

Double-click on Install and follow the prompts.  The installation
process automagically only selects the descriptors for formats that
do not already exist on your system - eg. your existing PNG datatype
will continue to be used for PNGs!  If you wish to override this,
run the installation through in Expert mode and manually select the
formats you want to use with jng.datatype.

History
=======

v1.3
* Shared objects version - no code changes
* Stopped the descriptors unnecessarily reading files

v1.2 (17.05.2008)
* Fixed the transparency.
* Fixed the MNG descriptor to give it a bit more priority as the
  JPEG one was being used for some files.  Please delete
  DEVS:DataTypes/MNG before running the installer to update.

v1.1 (14.05.2008)
First release, based on libmng 1.0.10
