 String::Approx 

and giffix (from giflib).several tools from

 giflib 

(also known as libungif).

ATTENTION: There has been a segfault discovered in both

 giftext 

and

 gocr 

Patches for the sources are to be found in the download directory of FuzzyOcr. Not using these can make problems under certain circumstances.

Notes for Fedora Core 5 (or higher) users: The package libungif-utils provides giffix.

...

Notes for Debian users: The package libungif-bin provides giffix.

Attention when using RedHat! The gocr RPM for RedHat is faulty and causes bad recognition results. Here is a quote from Ken Bass:

I installed gocr 0.40 using an RPM / (source RPM). For whatever reason, 
the RPM configures the gocr using 'configure --with-netpbm=no'. This 
netpbm=no option causes some images to not be decoded properly. I get 
much more garbage. I had to rebuild/reinstall gocr 0.40 without 
disabling netpbm for best results.

I've reported this to the gocr mailing list, sent him a sample image, 
and hopefully it will be fixed. He seemed to think it would be fixed in 
gocr, but I have no timeframe. In the meantime, those with problems, 
trying modiying the RPM gocr.spec file or build/install by hand.
