The application is Adobe Acrobat Pro (any volunteers for modifying  
it ? ;) ). The thing is Acrobat can process scanned books or brochures  
in a nice way (i.e automatically remove the middle shadow between the  
pages, auto-align rotated pages, do OCR and add text version of the  
scanned document to the .pdf file it creates, etc. ). My plan was to  
feed the image files to sane, then use a sane-to-twain bridge (which  
I've found to exist) on a windows or Mac OS X machine and then let  
Acrobat do whatever I need via the twain interface...

Yes, I am aware of the pnm back-end, but from the man page of sane and  
sane-pnm I learned close to nothing (not even how to use that back- 
end). Does the convert utility convert multi-page zipped tiffs to pnm  
file(s)? If not, which program can I use instead?

Thanks for any further advice...

Peter.

P.S.: I thought there must have been someone in need of similar  
functionality as I am and that some user-friendly way of just feeding  
any image file into a virtual scanner device would already exist... it  
seems such a natural feature to be implemented :)...
