Multiple columns text.

[Bonny]

Hello..

I have multiple column text. But tess just merge left and right column as one.
Is there some possibility to instruct tess where column is?
I can put out coordinates of columns but don't know how to pass that to tess.
Ie Is it possible to but 'bounding box' coordinate to commandline? (winXp)

Thanks..

p.s.
If it's possible it's probably throught commandfile. Is there any documentation of comandfile at all?

Hi Bonny,
The other open source/free OCR product OCRopus can handle layout. It
used to work with Tesseract, but I think it is totally independent
now...

OCROpus seems to be just for linux. No winXP executable found.

Tess does not accept coordinate arguments at command line, but does
recognize multiple-column documents beginning version 3.0. You can
pass coordinates programmatically. Try VietOCR for your documents.

Not possible to pas coordinates (varfile, configfile??)

I had precompiled tess 3.00.1 but doesn't recongnize two colons. Here is
example file. I use hOCR output.

[Bonny]

Huh..

No attachment alowed.
In meantime I try VietOCR but doesn't recongnize two colon too.

Hello....

About digging I find the why didn't work...
In download section there is main download tesseract-ocr-setup-3.00.exe
And bugfixes in tesseract-3.00.1.exe.zip

I find somewhere in page that -v switch is added in version 3 and above. (-v = version) So if we executed tesseract -v and have version before 3.0 the error is displayed and above 3.0 the version is printed.

I tested 3.00 and got error, and multicolon text doesn't work
I tested 3.00.1 and got error, and multicolon text doesn't work too.

So I can only concluded that posted binaryes wasn't version 3 but 2.xx ???
I try to build from source and unsuspected was sucessfuly build in 1'st try.

now tesseract -v show that is version 3.01 and I tested multicolon and works!

So binaries for windows are wrong labeled or outdated. So far I know the multicolon is feature of 3.00

Or I messed something other too?!?

Posted files are 3.00. But there was bug with initialization of segmentation mode. 

See http://code.google.com/p/tesseract-ocr/issues/detail?id=518. So feature was there but difficult to use for non programmers.

It is dangerous to make conclusion without knowledge ;-)
