pixie question

Post by nt » Mon Aug 21, 2006 10:41 pm

Hi,

I am getting a java.io.IOExcetion when I try the following line:

WmfFile wmfFile = new WmfFile(fis, -1,-1);

The stack trace states that "The given file is not a real metafile". I am extracting metafiles from ppts and then processing them, so I am not sure where this message is coming from.

Please help - thank you so much in advance!

Hi,

I'm quite sure, your metafile is missing the required header. Pixie checks for the magic numbers in these headers and grabs some additional information from there. Also: Pixie does only read WMF files (which is equal to the Windows 3.0/3.1 API), and not EMF files (Windows 9x and higher).

Regards,
Thomas

Thomas,

Thank you for your response. I was wondering if you have any suggestions on how to (a) fix this and/or (b) detect this? Is there a particular property of certain wmf's that makes them lack metadata? I am specifically dealing with wmf's - I check that that is the file format before I use any of the pixie API.

Thanks again!
