For anyone who wants to use/manipulate jpeg files in their own
applications, this library makes it very easy.

jpeg.library is a shared library that can be used to examine, load and save
jpeg images. You can have multiple jpegs objects (load/save), supports all
the standard jpeg quality and smoothing parameters and can scale loaded
images (smaller). Jpeg image data can reside on disk or in memory. You can
read and write application markers with simple tags, or read/write X and Y
aspect ratios/densities in a standard Adobe application marker.

Example programs included.

Version 6.2a adds the following features:

* Full application marker support. Markers may be read and written, or just
copied from a decompression stream to a compression stream.

* Read and write the X and Y aspect ratio to/from standard Adobe markers
(the defacto standard for storing this information).

* Library calls are provided to manipulate a stream's markers, or you may
manipulate the linked list of markers yourself (example code provided).

* Fixes a bug resulting in a small memory loss if an allocate of a
de/compression object fails.

* WarpUp version by Oliver Roberts.

* OS4 version by Darius Brewka

* Preferences program for applications to control how often progress
  callbacks are called. The OS4 Version of the Prefs tool is still

** This software is based in part on the work of the Independent JPEG
