Description Dominik Stadler 2016-11-28 10:53:27 UTC 
The Jenkins CI job which tries to run ooxml-tests without scratchpad currently fails at the following test, this indicates that currently Scratchpad is required for handling WMF pictures. See https://builds.apache.org/job/POI-no-scratchpad/lastFailedBuild/testReport/org.apache.poi.xslf/TestXSLFBugs/bug59434/ for details

Should we move these classes to main to not have this discouraged dependency from ooxml to scatchpad?

Comment 1 Andreas Beeker 2016-11-28 11:29:59 UTC 
I've already started yesterday to split them.
The solution for *slf is finished, i.e. I've created ImageHeader* classes in the main jar, but there are other OOXML->scratchpad issues to solve.

Yes, thanks, I  just go one issue after the other to finally remove this dependency. 

A few unit tests related to text-extraction are ignored right now as they include files for scratchpad-related formats, we`ll see if there are other problems after this one.
