Jpegoptim v1.4.0beta Copyright (c) Timo Kokkonen, 1996-2014. REQUIREMENTS Independent JPEG Group's jpeg library version 6a or later (jpegsrc.v6a.tar.gz) TESTED PLATFORMS Linux Solaris Darwin/OSX (compiles fine as 64bit app on Snow Leopard) INSTALLATION Installation should be very straightforward, just unpack the tar file, make necessary changes to the Makefile, and then compile the program. You may wanna do something like this: zcat jpegoptim-1.4.0.tar.gz | tar xf - cd jpegoptim-1.4.0 ./configure make make strip make install HISTORY v1.4.0beta - use memory (instead of temporary files) during optimization, support for input/ouput via stdin/stdout, other minor fixes & cleanup v1.3.1 - XMP marker support and new --csv option (by Matteo Croce), use DESTDIR instead of INSTALL_ROOT (by Samuli Suominen), changes to make compiling under Win32 and Win64 easier (thanks to Javier Gutiérrez), preserve permissions of files being optimized, skip symlinks (and other special files), other minor fixes v1.3.0 - support for progressive jpegs added (fixes long standing "bug" of progressive jpegs becoming non-progressive during optimization), new options --all-normal & --all-progressive for converting jpegs to non-progressive & progressive, new -S / --size option to set target size for output file (enables lossy optimization), updated GPL/Copyrights language (thanks to Nicolas Vieville) v1.2.5 - safer temp file handling (if mkstemps() available), patch to make "quiet mode" (-q) be quiet by Mathieu Malaterre v1.2.4 - new -T / --threshold option by Matteo Croce, minor fixes (potential memory leaks), merged some patches from Debian jpegoptim package (1.2.3-2) v1.2.3 - IPTC marker support by Dustin Ward, ICC profile support by Dwight Kelly, minor fixes v1.2.2 - Now Exif and COM markers are not discarded (all other markers are discarded as before). New options --strip-all, --strip-exif, and --strip-com added for controlling what markers to strip. v1.2.1 - fixed buggy temp file handling v1.2.0 - Added new options --overwrite and --preserve. GNU autoconf support added, also. v1.1 - new -f option, and other minor changes, improved support for other platforms v1.0a - some changes in docs & makefile v1.0 - first public release LATEST VERSION Latest version is always available from: http://www.iki.fi/tjko/projects.html Sources (GIT) https://github.com/tjko/jpegoptim Timo <tjko@iki.fi> 20-Apr-2014 $Id$
