changelog
Quote:
2010-09-21 - V3.00
* Preparations for thread safety:
* Changed TessBaseAPI methods to be non-static
* Created a class hierarchy for the directories to hold instance data,
and began moving code into the classes.
* Moved thresholding code to a separate class.
* Added major new page layout analysis module.
* Added HOCR output (issues 221, 263: thanks to amkryukov).
* Added Leptonica as main image I/O and handling. Currently optional,
but in future releases linking with Leptonica will be mandatory.
* Ambiguity table rewritten to allow definite replacements in place
of fix_quotes.
* Added TessdataManager to combine data files into a single file.
* Some dead code deleted.
* VC++6 no longer supported. It can't cope with the use of templates.
* Many more languages added.
* Doxygenation of most of the function header comments.
* Added man pages.
* Added bash completion script (issue 247: thanks to neskiem)
* Fix integer overview in thresholding (issue 366: thanks to Cyanide.Drake)
* Add Danish Fraktur support (issues 300, 360: thanks to
dsl602230@vip.cybercity.dk)
* Fix file pointer leak (issue 359, thanks to yukihiro.nakadaira)
* Fix an error using user-words (Issue 345: thanks to max.markin)
* Fix a memory leak in tablefind.cpp (Issue 342, thanks to zdravco)
* Fix a segfault due to double fclose (Issue 320, thanks to souther)
* Fix an automake error (Issue 318, thanks to ichanjz)
* Fix a Win32 crash on fileFormatIsTiff() (Issues 304, 316, 317, 330, 347,
349, 352: thanks to nguyenq87, max.markin, zdenop)
* Fixed a number of errors in newer (stricter) versions of VC++ (Issues
301, among others)

Dingo,

Thanks for this. I'm missing " liblept.so.2" in pup431 and in pup425.

Regards,

Sorry, I forgotten to add dependencies

here you can download

liblept
leptonica-1.68-i486.pet

I compiled tesseract against leptonica libs in order to add support for all available image formats

I'm having some trouble getting this to work, and I'm not sure where I've gone wrong.

I've d/l the Lucid version, the lib dependency, and the language pack. I've extracted the english language, so I think I've done everything, but I'm still lost.

I don't have a menu entry for Tesseract anywhere either.

I'm using Lucid 528.004 (frugal) with fluxbox.

Any suggestions would be appreciated.

Bones.

Read here about using Peasyscan with Tesseract.

If you open a terminal and type "tesseract", what happens?

Using LXTerminal, I get this result:
sh-4.1# tesseract
Usage:tesseract imagename outputbase [-l lang] [configfile [[+|-]varfile]...]
sh-4.1#


I'll have a read of peasyscan later, but I should point out that I don't have a scanner attached my puppy computer. The files I have are from another scanner.

Bones

In that case, you must run tesseract from the command line. If the source file is named "scan.tif", you will use the command
Code:
tesseract scan.tif scan

This will produce the file "scan.txt"

Since you have tesseract 3.0, I believe that the input must be in TIFF format. If your files are something else, you will need to run them through a converter like mtpaint.

As far I remember (I compiled tesseract some times ago) leptonica lib gives to tesseract ability to load most common images format
