- The Independent JPEG Group's JPEG software
- ==========================================
-
- This distribution contains MS-DOS executable copies of version 5 of the
- Independent JPEG Group's free JPEG software. You are welcome to redistribute
- this software and to use it for any purpose, subject to the conditions under
- LEGAL ISSUES, below.
-
- This software should run on any MS-DOS machine with DOS version 3 or later,
- although we have not tested it with anything older than DOS 5. You can also
- run it in a DOS window under Windows 3.x, and it should run under OS/2 as
- well. A minimum of 450Kb of free conventional memory is recommended.
- Extended or expanded memory is helpful; the more the better!
-
- For usage instructions, see the file usage.doc. Useful information can also
- be found in the JPEG FAQ (Frequently Asked Questions) article, posted
- regularly in the Usenet newsgroups comp.graphics and news.answers.
-
- Please report any problems with this software to jpeg-info@uunet.uu.net.

- ABOUT JPEG FILE FORMATS
- =======================
-
- CAUTION: Handmade Software's shareware PC program GIF2JPG produces files that
- are totally incompatible with our programs (and everyone else's too). They
- use a proprietary format that is an amalgam of GIF and JPEG representations.
- However, you can force GIF2JPG to produce compatible files with its -j switch,
- and their decompression program JPG2GIF can read our files. (Version 2.0 of
- GIF2JPG produces compatible files by default.)
-
- The file format we have adopted is called JFIF. This format has been agreed
- to by a number of major commercial JPEG vendors, and it has become the de
- facto standard. JFIF is a minimal or "low end" representation. Work is also
- going forward to incorporate JPEG compression into the TIFF standard, for use
- in "high end" applications that need to record a lot of additional data about
- an image. We intend to support TIFF in the future. We hope that these two
- formats will be sufficient and that other, incompatible JPEG file formats
- will not proliferate.
-
- Indeed, part of the reason for developing and releasing this free software is
- to help force rapid convergence to de facto standards for JPEG file formats.
- SUPPORT STANDARD, NON-PROPRIETARY FORMATS: demand JFIF or TIFF/JPEG!

- SOURCE CODE
- ===========
-
- The source code from which this software was generated is freely available.
- The "official" archive site for the source code is ftp.uu.net (Internet
- address 192.48.96.9). The most recent released version can always be found
- there in directory graphics/jpeg. This particular version is archived as
- graphics/jpeg/jpegsrc.v5.tar.gz. If you are on the Internet, you
- can retrieve files from ftp.uu.net by standard anonymous FTP. If you don't
- have FTP access, UUNET's archives are also available via UUCP; contact
- help@uunet.uu.net for information on retrieving files that way.
-
- The source is also available in the SimTel archives (graphics/jpegsrc5.zip)
- and on CompuServe (GRAPHSUP library 15, file jpsrc5.zip). These copies are
- ZIP files which may be easier for PC users to deal with.
-
- Note that the user interface used here differs from the Unix-style user
- interface found in the main IJG distribution. Source code for the DOS user
- interface is in file jpegaltui.tar.gz at ftp.uu.net.
-
- You are welcome to use the source code in other JPEG-related programs.
- The conditions for doing so may be found in LEGAL ISSUES, above.
-
- The executables in this package were compiled using Microsoft C 6.00A.
-
- The JPEG FAQ (Frequently Asked Questions) article is a useful source of
- general information about JPEG. It is updated constantly and therefore
- is not included in this distribution. The FAQ is posted every two weeks
- to Usenet newsgroups comp.graphics, news.answers, and other groups. You
- can always obtain the latest version from the news.answers archive at
- rtfm.mit.edu (18.181.0.24). By FTP, fetch /pub/usenet/news.answers/jpeg-faq.
- If you don't have FTP, send e-mail to mail-server@rtfm.mit.edu with body
- "send usenet/news.answers/jpeg-faq".
