Subject RE: Powerpoint conversion Help!!
Date Sun, 17 Aug 2003 18:27:35 GMT
I have a package that deals with the Escher format.

It's almost good enough to attach a picture (from BMP, JPEG, or WMF) into
HSSF. But not quite there yet. When it gets there, you will also be able to
do simple Escher type drawings (lines, shapes, call-outs - only if you
supply RTF, colors, arrows, etc.)

I was wondering the same thing, since Power Point extends the Escher format
(I called it MSOD for MS Office Draw. Java package name is
org.apache.poi.hdwgf  but I could change that).

I'm not sure I can help much with your problem but I have a question for
you.  Are you working on the escher format as part of your work?
