Thank you again. I think I'll stay with plain txt -- pdf looks too difficult to achieve.
Now, next problem: Everything worked fine with my 1-page test pdf. I now tried to do the same with a 30 MB 500 pages pdf. After running convert -density 300 test.pdf -depth 8 -strip -background white -alpha off test.tiff it took 2 hours and then suddenly everything went black and I could not do anything. I guess my Mac is too weak to handle this. I guess splitting the pdf in many parts is the only option left? With pdftk I used the command "pdftk test.pdf burst" to split the pdf in single pages. I then put around 50 pages in a new folder and used "pdftk *.pdf cat output test.pdf" to combine them. Is there a faster way to do this? I do not know with which command I could split the 500 automatically in bundles of 50. -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
