Hi,

Do I just replace the jai jpeg2000 jar with bfopdf-jj2000.jar for the
conversion to work?
I don't find any sample implementation code using jj2000.

Our situation is there is a jpeg 2000 embedded in pdf. We wanted to
converted pdf to jpg.
We are using the implementation code found in
https://github.com/faceless2/jpeg2000.
We got error No JP2 signature box. It seems like it is expecting us to pass
in a JP2 file.


As I wrote in the linked issue "The bfo.com fork doesn't create a 
plugin". They mention this too: "but with the JAI dependencies removed".


Pleased use the steps I described in

https://issues.apache.org/jira/browse/PDFBOX-1752 .

Please advise. Thank you.

Hi,

This is a bug in the oracle jpeg2000 decoder. See at the bottom of
https://issues.apache.org/jira/browse/PDFBOX-1752
on how to fix this. You need to get the decoder sources and make a few 
changes and build.

Re: Fwd: unable to convert scanned pdf to jpg using pdf box

[Tilman Hausherr]

Hi,

You need to have the JBIG2 decoder in your class path, see
https://pdfbox.apache.org/2.0/dependencies.html

Also update to 2.0.12 (current version) and make sure logging is enabled 
- if it had been, you would have received a message about the missing 
JBIG2 decoder.

[Tilman Hausherr]

Hello,

Please update to the current version (2.0.12) and include the JBIG2 decoder.
https://pdfbox.apache.org/2.0/dependencies.html

There should have been a log message telling you that the JBIG2 decoder 
is missing. If not, then please take care that log messages with warning 
or worse do appear.


That PDF seems to be recent. It also shows that a Xerox scanner wasn't 
properly configured - JBIG2 encoding shouldn't be used (just google 
"Xerox jbig2" :-)  )
