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.
