Hi All
I'm trying to use DDF to handle the Escher records in PowerPoint, as part
of my PowerPoint support. As part of this, I'm seeing quite a lot of
problems with the DDF support.
What's the best course of action here? Should I file a bunch of bug
reports, and discuss if I've correctly
Hi All
Couple of issues with the current EscherTextboxRecord
(msofbtClientTextbox, type 0xF00D) class:
When using DefaultEscherRecordFactory, I get back an EscherContainerRecord
instead of an EscherTextboxRecord. Anyone know why?
Also, in fillFields, it tries to create child escher records
Hi All
Next up with my DDF questions, we have EscherClientAnchorRecord
(msofbtClientAnchor, type 0xF010)
It seems convinced that it is of size 8 (header) + 18 (some standard data)
+ length of extra fields, so a minimum of 26. It doesn't seem to bother
checking the record header of this fact.
Hi All
In powerpoint documents, you find PPDrawing atoms. Within these you find a
number of Escher records, some of which have children. (I've attached an
example dump to the end of the email, if people are interested in what
records there are)
The problem I'm having is with getting a tree of

Hi All
With some more digging, it looks like the reason I'm not seeing child
records being created for Containers is because fillFields doesn't seem to
be being called.
Anyone know why DefaultEscherRecordFactory doesn't call fillFields on
newly created records?

It has been suggested (in Bugzilla) that my PowerPoint code's
