Re: Need advice: what pdf lib to use?
OK, but even in this case parsing the doc would not be a violation,
because actually what we need for lucene is just collection of terms. Has
nothing to do with printing or copying of _text_ pieces.
As long You provide method returning just Document (I mean lucene
document) permissions specified by the author of the PDF document are respected

In order to write software that consumes PDF documents you must agree to a

PDFBox complies with this statement, if there is software that does not
then they are in violation of copyright law.
That being said, PDFBox is open source so a user could make modifications
to the source code, or as a PDF library could change permissions on a
document.

Re: Need advice: what pdf lib to use?
I recently started to work on a project which needed to parse many documents, including pdfs, very quickly and on a large scale. PDF Box seems to look like the best choice except for it's obvious speed issue. Eventually I took the time to go into the pdf box source and rip out the individual string tokens. In doing so I lose the quality of some docs, kerning isn't there, special chars arn't avail, but you can even improve on that yourself a bit with a little more research. But parsing some pdf documents scaled down from 60 seconds to strip the raw text, to 5 seconds an exchange I gladly make for the speed improvement. It's open source, with any IDE, you should be able to trace the function calls to find where to rip out the data you need. -Chris Fraschetti On Mon, 25 Oct 2004 18:07:52 +0200, sergiu gordea <[EMAIL PROTECTED]> wrote: > Ben Litchfield wrote: > > >In order to write software that consumes PDF documents you must agree to a > >list of conditions.

I wanted to say something like this in one of my previous emails, when I
said that anyone can modify the code of
PDFBox to replace the restrictions
That being said, PDFBox is open source so a user could make modifications
to the source code, or as a PDF library could change permissions on a

This seems to me as beeing a business decision,
Iouli if your boss tels you that PDFBox is useless because it
prevents you to get the text from protected pdfs,
than you should say him ... I can fix it but it is not legal. You can
hack PDFbox, but before doing this you should
ensure that the authors let you do it.
All the best,

On the specific problem of the "dead loop", I reported an instance of

nightlies. I expect an official release will include this bugfix soon.
The file in question was unreadable with any PDF software I have, but
someone managed to create it somehow...

I've found pdfbox to be pretty good. The only time I get problems is
with corrupted or egregiously bad PDF files.

Hello all,
I need a piece of advice/experience..
What pdf parser (written in java) u'd recommend?
I played now with PDFBox-0.6.7a and would not say I was satisfied too
much
with it
On certain pdf's (not well formated but anyway readable with acrobate)
it
run into dead loop (this I could fix in code),
and on one file it produced "out of memory error" and killed jvm:( (this
problem I could not identify yet)
After all the performance was not too great as well: it took c. 19 h. to
index 13000 files (c. 3.5Gb)
Regards,
J.
On the specific problem of the "dead loop", I reported an instance of
this to Ben a week or so ago and he has fixed it in the latest
nightlies. I expect an official release will include this bugfix soon.
The file in question was unreadable with any PDF software I have, but
someone managed to create it somehow...

I've found pdfbox to be pretty good. The only time I get problems is
with corrupted or egregiously bad PDF files.

Re: Need advice: what pdf lib to use?
PDFbox stumbles also with "class java.io.IOException with message: - You
do not have permission to extract text" in case the doc is copy/print
protected.
I tested now the snowtide commercial product and it looks like it could
process these files as well. Performance was also not so bad. Unfortunatly
the test result could not be considered as 100%, because the free version
processed just first 8 pages. After all this product costs a fortune
(as long the company is ready to pay I don't realy mind:))

Please post any PDFBox issues you notice on the PDFBox sourceforge bug
list, if possible attach/email any problem PDFs that you encounter.
There are some efforts underway to improve the speed of PDFBox, you can
monitor the progress at
http://sourceforge.net/tracker/index.php?func=detail&aid=1046300&group_id=78314&atid=552832
As for other suggestions, I know some people have utilized xpdf(open
source but non Java) to extract the text.
