Re: SlideShow rendering issues

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
