Re: unable to convert scanned pdf to jpg using pdf box with JBIG2
ImageIO 3.0.2
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.
Please advise. Thank you.
Regards,
Ace

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 .
