PDF Text Stripper
Hi,
I have written a PDF library that can be used to strip text from PDF
documents. It is released under LGPL so have fun.
There is one class which can be used to easily index PDF documents.
pdfparser.searchengine.lucene.LucenePDFDocument has a getDocument
method which will take a PDF file and return a Lucene Document which you
can add to an index.
If you would like to see the quality of the text extraction you can run
pdfparser.Main from the command line which will take a PDF document and
write a txt file.
I am looking for any input that you might have. Please mail me if you
have any bugs or feature requests.
The library can be retrieved from
http://www.csh.rit.edu/~ben/projects/pdfparser/

I just took a look at JPedal and I'm very impressed. Extracted some text as
XML data no problem.
Amazingly also creates thumbnails of the PDF file which is something I've
needed but couldn't find...:)
Regards,
Kelvin

Hi,
I?ve used JPedal ( www.jpedal.org ). I?s distibuited under LGPL license and
extract raw text, among other uses.
I wrote code to extract text using Etymon PJ library, with PDF?s withs
propietary fonts, I needed to create a cross tabla to translate Unicode to
ASCII because Distiller inserts only a subset of Unicode tabla for each
propietary font.
JPedal has not problem with thats fonts and extract all text in XML,
suitalble for use with Lucene.

Can you send me the PDF document that you are having problems with and I
will look into it.
There are still some issues that I am working out with the spacing of
characters.

hi,
I downloaded the zip and quickly ran the demo on a few files, it displays
.notdef between words and there are spaces between every letter for words,
is there code in your dist. to remove these so that just terms remain?
