Andreas Lehmkühler resolved PDFBOX-1145.
----------------------------------------
Resolution: Fixed
Fix Version/s: 1.7.0
Assignee: Andreas Lehmkühler
Images most likely don't need any further resources than their own, so that
they can be extracted without parsing the content stream of the page itself.
But image masks like those in the given example use the current non stroking
color as stencil color. That value isn't present without parsing the content
stream of the page.
I fixed the NPE by using Color.BLACK as missing stencil color. This is only a
workaround, but I guess the best we can do in such cases.
