Re: Weird spacing in words

[Tilman Hausherr]

Looks like a different problem. Assuming you're using the latest 
version, you might want to try setting


PDFTextStripper.setSpacingTolerance()

the default is 0.5f

So try some values slightly above or below, i.e. 0.4f, 0.6f, etc.

another one is

setAverageCharTolerance()

the default is 0.3f.

Right.

Yeah I think that’s the best approach. Once you’ve fetched OPENSHIFT_DATA_DIR
from the environment then you can pass it to PDFBox by just setting the system
property via System.setProperty(“pdfbox.fontcache”, “...”);

Voila.

Weird spacing in words

[Augusto Ribeiro Silva]

Hi all,

I am using PDFBox java library to read the content of some PDFs and it seems 
like it inserts some weird (hyphen-like) spacing. I get the same result using 
the PDFBox-App command line util.

The es tab lish ment of an in te grated Part ner Re la tion ship Man age ment 
(PRM) sys tem can po ten tially ad dress sev eral as pets

I tried to extract text from the same PDF using the pdftotext command line 
utility it extracts the text correctly:
The establishment of an integrated Partner Relationship Management (PRM) system 
can potentially address several aspects 

Does somebody have any idea why PDFBox behaves in this way and any tips to 
fixing it? I am using TIKA but as I understood TIKA uses PDFBox for PDF 
processing underneath.

Best regards, 
Augusto

Numbers get reversed sometimes during conversion

[Shyam Sundar]

Hi,

I have come across an issue wherein while trying to covert PDFs (mainly of
RTL languages) into TXT, the numbers get reversed.

Please check the attached file, '2005' in heading has become '5002'.

It happens with the latest version too. Is this a bug ?

This is a PDF/A format by the way. Hope it is fully supported.

Thanks in advance.
