This is my command to ocr my incoming faxes on an hylafaxserver.
/usr/local/bin/abbyyocr9 -rl German -ic Uncompressed -if $tiff_file -
pem ImageOnText -pfpf LZWGray -pfpr 200 -f PDF -of $pdf
The resulting pdf and even the ocr quality is fine. I can view the pdf
in amost every pdf viewer and extract text.
But when i resubmit this pdf to my hylafaxserver to fax it to somebody
else, only a grey page is sent.
When i open this pdf in osx Preview and save it without any changes
using a new name and then submit it to my fax server the result is
If i try to submit a pdf with underlying text generated by omnipage
the resulting fax is ok.
In my opinion something must be mixed up in the resulting pdf which
refuses the correct pdf2tiff conversion.
Thank you very much in advance for any helpful hints.
