The Independent JPEG Group's JPEG software ========================================== README for release 5b of 15-Mar-95 ================================== This distribution contains the fifth public release of the Independent JPEG Group's free JPEG software. This software is the work of Tom Lane, Philip Gladstone, Luis Ortiz, Jim Boucher, Lee Crocker, George Phillips, Davide Rossi, Ge' Weijers, and other members of the Independent JPEG Group. IJG is not associated with the official ISO JPEG standards committee. This port for the Amiga is done by Günther Röhrich. I used the original jpegsrc.v5b.tar.gz archive ftp'ed directly from ftp.uu.net for compiling the programs. System requirements: - OS 2.0 or higher - programs with the ending .020881 will need a 68020/68881 (or better) - JPEGTMP: must be assigned to a directory with enough free disk space ******************** NEW IN THIS RELEASE: ******************** The ixemul.library is not needed any more. Starting with this release cjpeg and djpeg are using the Unix-like command line style. Redirection and piping is now fully supported. Examples: cjpeg inputfile >outputfile cjpeg outputfile djpeg -scale 1/4 inputfile | cjpeg >outputfile The last example creates a 1/4 scaled JPEG file of your inputfile. Note that a temporary ppm file will not be created. To use this with the standard Amiga shell you need one of those pipe archives: Aminet: util/shell/MJPipe09.lha util/shell/Pipe_1_5.lha util/cli/pipe3310.lha Use the -outfile option if you don't want to use redirection. New shell scripts for the jpegAGA program are also included in this release. They are now working with all versions of djpeg and not just with those using the "two- file" command line style. If you found a bug then please let me know about it. (Every behaviour that does not correspond to the original documentation is considered a bug.) If it is not Amiga-specific you may also report it directly to the Independent JPEG Group.
