-----------------------------------
Summary: doc bug - jpeg2000 support
Key: PDFBOX-4681
URL: https://issues.apache.org/jira/browse/PDFBOX-4681
Project: PDFBox
Issue Type: Wish
Components: Documentation
Affects Versions: 2.0.17
Environment: windows documented above but likely cross platform
Reporter: Chris Clark
# PDFs with jpeg2000 fail to extract, even if dependencies documented in
[https://pdfbox.apache.org/2.0/dependencies.html] are satisfied. There appears
to be an additional dependency on
[https://github.com/jai-imageio/jai-imageio-jpeg2000], without it get error:
{code}
Nov 09, 2019 11:04:07 AM org.apache.pdfbox.contentstream.PDFStreamEngine
operatorException
SEVERE: Cannot read JPEG2000 image: Java Advanced Imaging (JAI) Image I/O Tools
are not installed
{code}
Additionally for a novice user who is using the command line tool, it is *not*
clear how to the use the sample CLI application once the dependencies are
satisfied. For example, simply adding the three (3) jar files to the class path
is not sufficient, additionally the main jar file needs to be executed without
the -jar parameter and the entry classname specified (alternatively the jar
file contents need to be merged).
I found that the following was needed:
* jai-imageio-core-1.4.0.jar
* jai-imageio-jpeg2000-1.3.0.jar
* pdfbox-app-2.0.17.jar
and then call via:
{code}
REM Windows classpath separators used
java -cp
jai-imageio-jpeg2000-1.3.0.jar;jai-imageio-core-1.4.0.jar;pdfbox-app-2.0.17.jar
org.apache.pdfbox.tools.PDFBox ExtractImages TEST.pdf
{code}
Its possible there is a code solution to this but quick fix is to:
# document the jpeg2000 dependency as well as the (already) documented JAI
Image I/O need
# document how to then use these with the sample pdfbox app with an example
