Re: [tesseract-ocr] Re: Error opening traineddata files on Mac High Sierra
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.

[tesseract-ocr] Re: Error opening traineddata files on Mac High Sierra
It works! I am so relieved. Thank you all for the help. Still I have a couple of questions since I've read a couple of tutorials, each using other commands: 1. Converting my Fraktur pdf files in tiff I use imagemagick. Is this the right command? convert -density 300 test.pdf -depth 8 -strip -background white -alpha off test.tiff 2. For tesseract then the command: tesseract test.tiff outtest -l deu_frak With this I get a txt version of the tiff. 3. Not that it matters too much (I'm over the moon that it works like this), can I get as an output instead of a txt the original pdf just with a search-and-copy-function? -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.

Nothing happens if I type in echo $TESSDATA_PREFIX I thought about installing tesseract 4.0beta, is there a step-by-step-guide how to do this? with brew install tesseract I cannot choose the version, i.e. it's 3.05.01 Am Dienstag, 10.

Re: [tesseract-ocr] Error opening traineddata files on Mac High Sierra
Thank you for your reply. I used the command following this guide https://www.youtube.com/watch?v=QhJiOCwz-_I -- if it's wrong, then I will not follow this guide anymore. Yes, I have Fraktur.traineddata in usr/loca/share/tessdata I do not know how to change "the TESSDATA_PREFIX environment variable" -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.

I downloaded deu_frak.traineddata Fraktur.traineddata and frk.traineddata to usr/loca/share/tessdata. But when using $ tesseract file.tiff -l Fraktur Fraktur I get the error message Error opening data file ./tessdata/Fraktur.traineddata Please make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your "tessdata" directory.
