Extracting WMF image from PPT file

[Gaurav]

Hi All,

I need to extract the WMF image data from the PPT file. I have read
the specs and have written the code in c++ to extract the same and was
able to do so. What I get is compressed WMF as written in the Office
drawing specifications and they have mentioned that to decompress it
to original data you should use deflate with 32 K window, similar to
PNG image. I have done so but not able to decompress the data by using
the deflate algorithm, though it works perfectly well with the PNG
case. I'm using the standard zlib code available from the net for
decompressing it.

Any help from where I can get the source code which can decompress the
WMF data.


Thanks

Gaurav
