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 .
Tilman
Please advise. Thank you.
Regards,
Ace

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.

Hi,
The error is Cannot read JPEG2000 image: java advance imaging(JAI) image
i/o tools are not installed.
Subsequently I added jai-imageio-jpeg2000 1.3.0 and jai-imageio-core
1.4.0
and the image converted has black dots all over.
Pdf and converted image can be found in google drive:

Thank you.

Hi,
I am using pdfbox 2.0.12 with extension, JBIG2 ImageIO 3.0.2. I am
unable to convert the attached pdf to jpg. Converted jpg show white
background only.
Hello,
Please upload your PDF somewhere, PDF attachments are usually deleted.
Please tell also how you converted. (Code or command line utility) Also
tell whether there were any log messages.
