OCR on Linux: great news

[Willem van der Walt]

Hi,
I have compiled and tested tesseract.
IMHO it is better than gocr and ocrad, but it is finniky about the images 
it handles.
It does not just ocr any tif file. It has to be at specific resollution 
and things like that.
There is a script that prepare the image to work.
With image magic one can convert whatever into the required .tif.
I had a funny experience with this program on my fedora 3 box.
It compiled, but hung when I ran it. Under Debian, it worked.
I suspect some gcc version issue.
It is good news in general, and if I had to do a lot of OCR now, I would 
have used it as is.
I would say it is about like the old easy scan stuff from Arcenstone.
It is also rather slow.
Regards, Willem
