Linux/BSD/Mac OS X ports of Ken Silverman's Utilities
Here are Linux, BSD, and Mac OS X ports of certain popular DOS/Windows utilities written by Ken Silverman.
NOTE: The source code to these tools is not being made public at this time.
Linux and BSD
Linux binaries were compiled on Debian 7.8 (glibc 2.13 with GCC 4.7.2). BSD binaries were compiled on FreeBSD 10.1. Included in the tarball are binaries for i686 and x86_64/amd64.
If you know that your system is running a compatible libc version, you should use the "dynamic" version of the tools. If your libc is incompatible, or you don't know and wish to play it safe, use the "static" version.
Mac OS X
Mac OS X binaries are for 64-bit Intel Macs running Snow Leopard (10.6) or newer. Homebrew users can install PNGOUT by running brew install jonof/kenutils/pngout in a Terminal window, or for KZIP/ZIPMIX run brew install jonof/kenutils/kzipmix.
|PNGOUT (release 20150319)|
|KZIP and ZIPMIX (release 20150319)|
- 20150920 PNGOUT (Mac OS X only)
- Rebuilt as 64-bit only with Xcode 7 since building 32-bit with optimisations gives a buggy binary. The previous release was not built with optimisations and was much slower than it should be.
- 20150319 PNGOUT, KZIP, ZIPMIX
- Supports a maximum of 2048 Huffman blocks. Also, 64-bit builds for all tools.
- 20130221 PNGOUT
- Updated to Ken's latest version. No longer assumes a suggested palette always contains all of the image's original colors.
- 20120530 PNGOUT
- Better randomness when the
-rswitch is used.
- 20110722 PNGOUT
- Updated to Ken's latest version.
-f5now generates block boundaries in a consistent and correct manner.
- 20110415 PNGOUT
- Updated to Ken's latest version. Adds
-f6option to reuse filters line-by-line from a source PNG file.
- 20110109 PNGOUT
- 64-bit Linux binaries, and support for 64-bit on OS X too.
- 20091108 PNGOUT, ZIPMIX
- Adds meaningful exit codes, other bug fixes to pngout. Adds additional mix modes to zipmix.
- 20090913 KZIP/ZIPMIX
- Bug fix for
- 20070805 KZIP/ZIPMIX
- No changes to the core of these since last release, but parameter handling doesn't consider '/' as a switch anymore, so you can use full paths now.
- 20070430 PNGOUT
- Updated to Ken's latest version. Debut of the BSD builds.
- 20070110 PNGOUT
- Updated to Ken's latest version. Also, implemented a more conventional approach to prompting for yes/no and killing the program. Control+C pressed once during an optimisation will cause PNGOUT to stop at the end of the current pass. Pressing it a second time will kill the program immediately.
- 20061021 KZIP
- Updated to include Ken's improved *nix path recursion and file handling.
- 20060923 KZIP
- Directory recursion works properly now in Linux/OSX. zipmix unaffected.
- 20060827 PNGOUT
- Updated to Ken's latest version of PNGOUT. Fixed some crashes that surfaced on the Athlon-optimised build. First universal-binary release for OS X.
- 20060524 PNGOUT
- Update to Ken's latest version of PNGOUT
- 20051122 KZIP/ZIPMIX
- Update to Ken's latest version of Win/DOS code
- 20051112 PNGOUT
- Debut of PNGOUT for Mac OS X, and corresponding update of Linux version.
- 20050613 KZIP/ZIPMIX
- Initial release, ported by Ken Silverman
- 20050422 PNGOUT
- Long overdue update to incorporate Ken's fixes and updates to date.
- 20050110 PNGOUT
- New build with Ken's latest round of updates.
- 20040928 PNGOUT
- Update to newest version of Ken's picture loading code, applied Ken's batch of fixes to the main pngout code, and addition of a Unix filter-like mode of operation. eg. pngout - - < input > output. Note that optimising very large images (>= 1MB in size) in filter mode might result in a damaged output file due to a limitation that currently exists.
- 20040716 PNGOUT
- Update to disable the automatic appending of a .png extension to source filenames that don't specify one.
- 20040713 PNGOUT
- Update to correct a commandline parameter problem which meant any fully-qualified file path was being treated as a switch parameter.
- 20040517 PNGOUT
- Another minor update to 2004-05-14 release to fix a GIF reader picture size bug.
- 20040516 PNGOUT
- Minor update to 2004-05-14 release to fix a bug introduced in that update.
