Tilman Hausherr commented on PDFBOX-81:
---------------------------------------
I have a similar problem with 1.4.0, some PDF files are JBIG2 encoded and all I
get when extracting the images are white pages, not even a log error or an
exception. Including the levigo-jbig2-imageio-1.1.jar in the lib list doesn't
help. Same when using the jbig2.jar from the JPedal site. Same when copying it
in the lib/ext directory of the JRE.
About the "how should we proceed" question - why not simple document it on the
dependency page?
