Hi again,

Well, it turned out to be fairly simple to add trailer support for CRW images once I learned how DPP adds the trailer to these files. (I finally got DPP to install properly so I could test this out, otherwise I couldn't have done this -- there is a trick to adding trailers to CRW images since the CRW itself has an important trailer that must come last in the file.)

I have just released 6.52 which now supports trailers in CRW images, so the commands in my last post will now work for CRW too.

BTW, I took a quick look at where the crop information is stored in the CanonDPP trailer, but haven't yet figured out the structure well enough to be able to reliably extract this information. But this is on my list of things to do.
