Since tesseract will only operate with uncompressed TIFF files you need just a few extra steps to achieve compatiblity with xsane.

goto : click Preferences --> Setup --> Filetype

for the TIFF options

Set compression rate to 1

in the next three TIFF dialong boxes select no compression.

clock OK

click Preferences again and select SAVE settings.

When scanning a file for OCR in the XSANE menu I select type :TIFF

color : gray
enter 300 for scan resoultion

And save the filename with extention .tif not .tiff.

Then when finished you invoke tesseract from the command line with

tesseract filename.tif outputname

Come on people, why did no one report before now that the package was broken?
Or did it work in older versions of Puppy? Maybe petget was different...

[ndujoe1]

It is not broken I forgot to post that you need to move the tesseract location from /local/tessearct to /usr/local/tesseract. Then you will be able reference it from the command line. It works well on my machine.

[disciple]

Yes, I know the build isn't broken, and neither are your instructions... but my package is.
I obviously packaged it wrong... unless my package somehow got replaced by a different, broken one.

I'm using Puppy 431. I read only the first post in this thread and got it working -- to a fashion -- the command simply returned the dots per pixcel and size of the image file. A 1 byte file was made containing a new line character. No error on the command line. Not even in /log/var/messages . Check for dependencies form the menu lists none.

Now I see ndujoe1 says it needs xsane. Which xsane pet from the official Puppy 4 repo should I use and does that need sane?

There is a py/gtk gui for tesseract at http://groups.google.com/group/ocropus/files/ that is worth looking at. Just find guitesseract.py on that page.
There are a couple of other guis I'm still looking at.

[abushcrafter]

That GUI looks promising. Thanks.

There's another py/gtk gui at http://ftp.gnome.org/pub/GNOME/sources/ocrfeeder/0.6/
This one is a bit more capable (e.g. page layout analysis) and looks more like it will be maintained.
You need to comment out one line of code which requires Gnome support, just to display the about page !

It also uses unpaper, which I posted above, and requires libgoocanvas and pygoocanvas and the python imaging library.
It exports to ODF or html, but unfortunately this isn't working for me; I think my python imaging library may be faulty. If it does work for anyone, please let us know which PIL and which python you're using.

[disciple]

I couldn't find a goocanvas that worked for me, so here's the one I built, and a repackaged py-goocanvas stolen I think from debian.

The other gui for tesseract is at http://sourceforge.net/projects/ocrgui/
It is in C/GTK (yay - no python ) but I suspect is not as capable.
My current puppy doesn't have a new enough GTK to try it, although I think the latest puppies do. You'll also need to install hunspell (or hack it to use enchant instead ) and it says imagemagick convert.

[abushcrafter]

There is a new version of tesseract out.

Tesseract-GUI
Juan Ramon Castan has improved on the work of Filip Domenic "guitesseract.py". I did not manage to ocr a image with it because the language drop down box had no options.

While on Source Forge I also found another tesseract GUI: http://sourceforge.net/projects/gimagereader/

And now what is your favorite OCR +GUI? What do you use?

Happy New Year
