[fprint] Open stored images

[Pavel Herrmann]

Hi,

I presume that this image stuff is not supported by libfprint for 
security reasons, but as it depends on imagemagick there must be some 
internal functions that work with the print in the form of an image. the 
first place I would look into would be the source code of libfprint, it 
should be there somewhere. After you find the process of generating 
fprint data structures from images gained from scanners, you should be 
able to write a little conversion tool yourself.

I hope it works
Pavel
