This is release 3 of the port of libjpeg 6b with lossless crop to MSDOS/DJGPP.

  DJGPP specific changes.
  =======================

  This port of jpeg 6b supplies, apart from all features known from the previous
  release of the jpeg6b port, lossless crop, which discards data outside a given
  image region but losslessly preserves what is inside.
  The patches to implement this functionaly has been downloaded from:
    <http://ftp.debian.org/debian/pool/main/libj/libjpeg6b/libjpeg6b_6b-14.diff.gz>
  for lossless crop and applied to the standard jpeg-6b sources available at:
    <ftp://ftp.imagemagick.org/pub/ImageMagick/delegates/libjpeg-6b.tar.bz2>
  Apart from providing lossless crop, the goal of this port is to use the
  standard configure scripts distributed with the package to configure and
  compile the sources and not relay anymore on the special makefile and config.h
  files for djgpp (usualy not well maintained) distributed with the package.
  There are only minor changes to the sources.  This concerns certain missing
  function declarations in a header file.  Apart from this, only the usual
  configuration files have been added, especialy sed scripts to fix the libtool
  files (ltmain and ltconfig).  They are located in the /djgpp subdir.
  The diffs documemts the changes required to implement lossless crop, to the
  header and the Makefile.in to get a working Makefile.

  To configure and compile the package and later to use it, you will have
  to install the zlib and the png port available at ftp.delorie.com and
  mirrors as:
    ftp://ftp.delorie.com/pub/djgpp/current/v2tk/zlib123b.zip
    ftp://ftp.delorie.com/pub/djgpp/current/v2tk/png1222b.zip
  or:
    ftp://ftp.delorie.com/pub/djgpp/beta/v2tk/zlib123b.zip
    ftp://ftp.delorie.com/pub/djgpp/beta/v2tk/png1222b.zip
  Of course, you can download a newer version of zlib and/or png if available.
  The zlib and png stored in /current have been compiled with djdev203 and are
  intented for use with Win98SE. Those ones from /beta are compiled with
  djdeb204 beta for the use with WinXP-SP2.
    
  Please note that there is a second port of jpeg6b called ljpeg6b.  That one
  has identical functionality than this one except that it offers lossless
  compression/decompression for JPEG too.  You can ***NOT*** have installed
  both ports, jpeg6b and ljpeg6b, at the same time.  This is because all
  headers and libs  have the same name, so they will overwrite each other.
  I have no intention to resolve this name conflict.

  Please **read** the docs.



  The port consists of two packages that have been compiled using djdev203 and
  that can be downloaded from ftp.delorie.com and mirrors as (timestamp 2007-10-26):

    libjpeg 6b scripts, headers, libs and man format documentation:
    ftp://ftp.delorie.com/pub/djgpp/current/v2tk/jpeg6bb.zip

    libjpeg 6b source:
    ftp://ftp.delorie.com/pub/djgpp/current/v2tk/jpeg6bs.zip


  For the convenience of the WinXP users the binaries has been produced
  a second time using the djdev204 beta library. This package is available
  at ftp.delorie.com and mirrors as (timestamp 2007-10-26):

    libjpeg 6b scripts, headers, libs and man format documentation:
    ftp://ftp.delorie.com/pub/djgpp/beta/v2tk/jpeg6bb.zip

  When downloading these ports, please pay attention to the timestamp to
  avoid downloading of old versions of these ports.  You can always check
  the release number by inspecting the .dsm file.


  Send libjpeg specific bug reports to <jpeg-info AT uunet DOT uu DOT net>.
  Send suggestions and bug reports concerning the DJGPP port to
  comp.os.msdos.djgpp or <djgpp AT delorie DOT com>.


Enjoy.
