It may be possible to use OLE for decoding of 34719

or to figure out which internal codec is used. MS quite often reuses stuff with a new name.

btw: Tiff tag 37680 in these MDIs is in MSCD format containing the standard document infos.

Martin,

Since this all read as Greek to me, I decided to try to find out more info on these terms through some google searching.

>From my investigation, I think you are saying that these image files are in a format used by an old version of MS office (2003), where MDI means Microsoft Document Image format and MSCD is the Microsoft Secure Content Delivery program. I think this is saying that Microsoft defined their own codec for image storage in MS Office 2003. On one google result that I found, it appears that MS has abandoned this image format in later versions of MS Office.

Is this what you were saying?

Also, isn't OLE (Object Linking and Embedding) another MS-only standard that doesn't help anyone using a non-MS platform?

Thanks,

Gene Amtower
