Hello,
I'm so to say the successor of Christian in this matter which he had asked you
in April this year. Because we don't know whether Christian has got any answers
from you, but the problems still exists, please let me ask again, how to
extract SmartArt graphics/objects from ppt?
Thanks in advance
Michael

I don't know enough about SmartArt to know the answer, but I can tell you the
approach you'll need

What you'll probably need to do is look at the Microsoft Binary File Format
documentation, and see what kinds of records / resources SmartArt gets stored
in. Next, try the hslf.dev tools to see if POI already has read support for
them. (If it's Escher / DDF based, we probably do, if not we may not). If
there's read support missing, add in code for the required additional records.

Finally, once the appropriate records are identified and being read, write some
high level usermodel code to access them and return the interesting
information, then submit a patch + unit tests here so we can roll it into POI!
