[sane-devel] XSane and Tesseract

[Mike CALDER]

Thanks Jeff,

Always happy to give all the options a go and I have installed gscan2pdf
and rescanned my original test.

Not sure whether the list will get the attachments but I assume you will.

result.txt is what I obtained using tesseract from the command line
having scanned just that part of a letter with XSane.

I then corrected that text to give DFRDB.odt which was the original.

DFRDB2.txt is the result that I have cut from the scan of the WHOLE
letter using gscan2pdf and tesseract as the chosen ENGINE and you can
see it is not as good as result.txt.

I think this is because I had to scan the WHOLE letter including the
crap of letter head, hand written signature and even some pencil notes I
had written on the bottom. This may well have confused the OCR.

I have just imported out.gif into gscan2pdf and then done an OCR
[tesseract]from Tools -> OCR and as you can see from DFRDB3.txt the
results are identical.

I may be wrong but even though there is a PREVIEW tab I do not seem to
be able to do a preview scan and the select a PART for a partial scan.

Hope this explanation is not too complicated.

Look forward to your comments.
