Hi!
I'm totally new to Apache PDFBox to please bear any stupid question:-)
In my work I do some digital archiving where I usually OCR scanned PDF-images
with Tesseract and then do the conversion from PDF to PDF/A-1b with Ghostscript.
However, there has recently been a change in the OCR specifications - don't
really know when and exactly how - but the consequences are that Ghostscript
now is mangling and altering the OCR so it can't be used. As what I understand
it has something to do with the ToUnicode CMap processing.
However I tried some other software to do the conversion and the problem does
not occur there. That's why I also would like to try to do the conversion with
PDFBox to see what happens.
The problem is I have absolutely no idea how to do this. I'm not really in to
java-based software. Can it be done nad how is it done? Preferably from the
Linux commandline.
I saw this https://pdfbox.apache.org/1.8/cookbook/pdfacreation.html but I can't
make any sense out of it.
Is it possible something like this:
java -jar pdfbox-app-x.y.z.jar Convert [OPTIONS] <inputfile> [outputfile]
(where options might be compability level)?
We don't have a tool that converts PDF to PDF/A-1b (there are commercial
tools that do that, e.g. from Callas or PDF-Tools). It might be possible
to implement this if the flaws are known in advance. Usually the meta
data and the output intent are missing, but there might be much more.
