Hi folks,

If it is of any interest, I bashed together a small script that will 
copy the preview JPEG (which I believe is full size and already 
processed) out of Pentax RAW (PEF) files.

The script works (using ufraw-batch) against either a whole directory or 
will convert files based on names supplied, either single or multiple files.

Once the JPEG has been extracted the script then copies the XMP file 
from the PEF to the JPEG and uses exiftool to write the EXIF information 
from the PEF to the new JPEG as well.

In my current work-flow I keep everything RAW and only convert a few of 
the files to JPEG and process those by hand, but the ones I can't quite 
ever get where I want, these scripts come in incredibly handy.

I can post them if folks want... I'm not certain if that's against the 
list policy.  The script is about 50 lines long.

Now... if someone could figure out how to hook this script directly into 
Digikam I'd be ecstatic!
