Comment 8 for bug 483391

If this helps... For English OCR, I have some helper scripts. I don't remember where I found them, prob. Ubuntu Forums.

/ocr$ ls
ocr.sh pdf2tif usage.txt

/ocr$ cat usage.txt
to generate a txt from a pdf # uses pdf2tif as a helper script
./ocr.sh <filename>.pdf

to produce only a tif from a pdf
./pdf2tif <filename>.pdf

/ocr$ cat ocr.sh
#! /bin/sh -e

# takes one parameter, the path to a pdf file to be processed.
# uses custom script 'pdf2tif' to generate the tif files,
# generates them at 300x300 dpi.
# drops them in our current directory
# then runs $progdir/tesseract on them, deleting the .raw
# and .map files that tesseract drops.

./pdf2tif $1

# edit this to point to wherever you've got your tesseract binary
progdir=/usr/bin

for j in *.tif

    do
    x=$( basename $j \.tif )
    ${progdir}/tesseract ${j} ${x}
    rm ${x}.raw
    rm ${x}.map

# un-comment next line if you want to remove the .tif files when done.
# rm ${j}
done

/ocr$ cat pdf2tif
#! /bin/sh -e
