This is one of those note-to-self type of posts. Just went through the exercise of installing a number of PNG tools on the Mac and here are some notes. The instructions below should probably work on any unix box.
AdvDef, AdvPng, ...
There is a number of Adv* tools (advdef, advpng, advmng, advzip) packed together as AdvComp. Installation difficulty: fairly straighforward.
Download:
$ curl http://softlayer.dl.sourceforge.net/sourceforge/advancemame/advancecomp-1.15.tar.gz \
> advcomp.tar.gz
Uncompress:
$ tar -xzvf advcomp.tar.gz
Compile and install:
$ cd advancecomp-1.15/ $ sudo ./configure $ sudo make install
Test:
$ advdef advancecomp v1.15 by Andrea Mazzoleni Usage: advpng [options] [FILES...] Modes: -z, --recompress Recompress the specified files Options: -0, --shrink-store Don't compress -1, --shrink-fast Compress fast -2, --shrink-normal Compress normal -3, --shrink-extra Compress extra -4, --shrink-insane Compress extreme -f, --force Force the new file also if it's bigger -q, --quiet Don't print on the console -h, --help Help of the program -V, --version Version of the program
Excellent! Next.
OptiPng
OptiPng is another easy install.
Download and decompress:
$ curl http://superb-west.dl.sourceforge.net/sourceforge/optipng/optipng-0.6.3.tar.gz \
> optipng.tar.gz

OptiPNG 0.6.3: Advanced PNG optimizer.
Copyright (C) 2001-2009 Cosmin Truta.
Synopsis:
optipng [options] files ...
Files:
Image files of type: PNG, BMP, GIF, PNM or TIFF
Basic options:
-?, -h, -help show the extended help
-o <level> optimization level (0-7) default 2
-v verbose mode / show copyright and version info
Examples:
optipng file.png (default speed)
optipng -o5 file.png (moderately slow)
optipng -o7 file.png (very slow)
Type "optipng -h" for extended help.
Beauty! Next - pngout.
PNGout
PNGOut's source is not distributed openly. But there are binaries for a number of platforms here.
Download:
$ curl http://static.jonof.id.au/dl/kenutils/pngout-20070430-darwin.tar.gz \
> pngout.tar.gz

$ tar -xzvf pngout.tar.gz
This way you end up with a binary named pngout-darwin. Rename and move somewhere where executables live:
$ sudo mv pngout-darwin /usr/bin/pngout
Test:
$ pngout
PNGOUT [In:{PNG,JPG,GIF,TGA,PCX,BMP}] (Out:PNG) (options...) Apr 30 2007
by Ken Silverman (http://advsys.net/ken)
Mac port assistance by Jonathon Fowler (http://jonof.edgenetwork.org/pngout)
PNGOUT optimizes PNG size losslessly using my own deflate algorithm (not Zlib)
With the right options, it can often beat other programs by 5-10%. Options:
-c# PNG output color type: 0=Gray, 2=RGB, 3=Pal, 4=Gray+Alpha, 6=RGB+Alpha
-f# PNG output filter...
PngRewrite
PNGRewrite was a little trickier, until I realized I need to install libpng first.
Download and install libpng:
$ curl ftp://ftp.simplesystems.org/pub/libpng/png/src/libpng-1.2.37.tar.gz \
> libpng.tar.gz
$ tar -xzvf libpng.tar.gz
$ cd libpng-1.2.37/
$ sudo ./configure
$ sudo make install
Download, unzip pngrewrite:
$ curl http://entropymine.com/jason/pngrewrite/pngrewrite-1.3.0.zip \
> pngrewrite.zip
$ unzip pngrewrite.zip
Compile pngrewrite (the make file didn't work for me) and copy the binary where executables are comfortable.
$ gcc -lpng pngrewrite.c -o pngrewrite $ sudo cp pngrewrite /usr/bin/
Test:
$ pngrewrite pngrewrite v1.3.0: PNG image palette optimizer Usage: pngrewrite infile.png outfile.png
That's all, folks
Installing PNGCrush? Blogged before.
And if anyone has an idea how to get deflopt installed, please comment.
