Hi Andreas
To get in touch with POI and my issues I dumped out a down scaled sample.
The sample has a master with an image and some other parts.
I focused on the image because it is not rendered.
First I remarked that the record type is sometimes cast to short.
But the type is an unsigned 4 byte number that does not fit into a
singed short.
Unfortunately removing the casts and defining the type to integer
changes nothing.
I printed out the record types which POI finds.
But I don't see any bitmap record.
See below the dump of the records.

Any suggestion which record represents the image?
Do you know a software to analyse/visualize the binary data of the
Powerpoint?
Many Thanks

Hello Bernhard,
I take care about rendering issues in HSLF/XSLF.
Either create a new bugzilla entry [1] with files/attachments which we
can put into our test data corpus (preferred).
Or get in contact with me directly and provide me the files and I try
to fix the implementation.
Out of scope are Word-Art and Charts, as those are a different beast.
For the time being, you might want the nightly a try - see
"Instructions to run":
http://poi.apache.org/components/slideshow/ppt-wmf-emf-renderer.html
If I commit any fixes, you'll have a fast feedback, if the issues were
resolved.
Best wishes,
Andi
