------------------------------------------------------------------
on my Linux box this works
{code}
java -jar pdfbox-app-2.0.17.jar ExtractImages Test.pdf
{code}
Is the above issue Windows specific? Or only needed if the jai-xxx.jar files
need to be referenced?

> 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
> Priority: Major
>
> # 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
