[Typo3-debian] GD and ImageMagick Packages for Debian and the "LZW" problem

due the powerfull package-format of debian, you only have to download 
the source-package

$: apt-get source imagemagick

get the build-depends

$: apt-get build-dep imagemagick

cd imagemagick-....

edit debian/rules and uncomment the lzw-part

dpkg-buildpackage -rfakeroot -us -uc

and you  get the deb with lzw, no problem with that.

We don't support lzw because only that way we can get the packages into 
the official tree some day.

In a few days the lzw algorithm patent expires and the official 
lzw-enabled packages are possible.

I have packaged graphicsmagick for debian sid, see [1]. Michael Stucki 
has tested them with a wrapper script and they seem to work. But 
graphicsmagick is a fork to provide a more stable api and not to provide 
  the lzw algorithm, both projects provide it but will be disable it by 
default.
