[Digikam-users] How do I crop an image?

[Chris G]

This is silly, I can't find where to crop an image in Digikam!  :-)

I'm sure it used to be straightforward but I can't find it at all now,
this is after a system upgrade (xubuntu 10.04 to 10.10) so now I'm
running Digikam version 1.4.

Aha, I've just got a little way, select an image and click on Edit but
unfortunately 'Crop' is greyed out so I still can't crop the image.

What have I got wrong?
