Extracting thumbnail/preview from Visio files

[nitai]

Hi all,

Trying to extract thumbnail from visio file here (is it even possible?).

When I run -X I get the "FlashPix:ThumbnailClip" and a message of "(Binary data 19904 bytes, use -b option to extract)".

Running:

Code Select Expand

exiftool -b -ThumbnailClip Timecard.vsd > Timecard.jpg

Just gives me a file with 20k and is not a recognizable image format. Tried to convert it with ImageMagick or alike, does not work either.

Anybody has any clue? Thank you.

PS: On a Mac 10.8.2 with 9.03

I checked the FlashPix specification:  "The thumbnail image is stored in CF_DIB format which is a simple rectangular array of pixels with a small header (see Programming Windows, Charles Petzold, 1990, Microsoft Press.)".

I don't know if this helps.
