PDF Box generating blank images due to JBIG2 Images in it - pdf-generation

Question

Let me give you an overview of my project first. I have a pdf which I need to convert into images(One image for one page) using PDFBox API and write all those images onto a new pdf using PDFBox API itself. Basically, converting a pdf into a pdf, which we refer to as PDF Transcoding.
For certain pdfs, which contain JBIG2 images, PDFbox implementation of convertToImage() method is failing silently without any exceptions or errors and finally, producing a PDF, but this time, just with blank content(white). The message I am getting on the console is:
Dec 06, 2013 5:15:42 PM org.apache.pdfbox.filter.JBIG2Filter decode
SEVERE: Can't find an ImageIO plugin to decode the JBIG2 encoded datastream.
Dec 06, 2013 5:15:42 PM org.apache.pdfbox.pdmodel.graphics.xobject.PDPixelMap getRGBImage
SEVERE: Something went wrong ... the pixelmap doesn't contain any data.
Dec 06, 2013 5:15:42 PM org.apache.pdfbox.util.operator.pagedrawer.Invoke process
WARNING: getRGBImage returned NULL
I need to know how to resolve this issue? We have something like:
import org.apache.pdfbox.filter.JBIG2Filter;
which I don't know how to implement.
I am searching on that, but to no avail. Could anyone please suggest?

Answer 1

Take a look at this ticket in PDFBox https://issues.apache.org/jira/browse/PDFBOX-1067 . I think the answer to your question is:
to make sure that you have JAI and the JAI-ImageIO plugins installed for your version of Java: decent installation instructions are available here: http://docs.geoserver.org/latest/en/user/production/java.html
to use the JBIG2-imageio plugin, (newer versions are licensed under the Apache2 license) https://github.com/levigo/jbig2-imageio/

Answer 2

I had the same problem and I fixed it by adding this dependency in my pom.xml :
<dependency>
<groupId>org.apache.pdfbox</groupId>
<artifactId>jbig2-imageio</artifactId>
<version>3.0.2</version>
</dependency>
Good luck.

Answer 3

I had the exact same problem.
I downloaded the jar from
jbig2-imageio
and I just included it in my project's application libraries, and it worked right out of the box. As adam said, it uses GPL3.

Answer 4

Installing the JAI seems not needed.
I only needed to download the levigo-jbig2-imageio-1.6.5.jar, place it in the folder of my dependency-jars and in eclipse add it to the java build path libraries.
