Help me import edited 'versions' of images from Picasa

That's why I'd like to ensure the XML I create follows any standard that
Digikam follows, if possible. Looking at the .picasa.ini files today
confirmed my expectations that it'll be too difficult to convert the the
non-destructive editing parameters to those that Digikam use. We have
parameters like:
crop=rect64(fc40570fffff5ae)
filters=finetune2=1,0.526316,0.000000,0.000000,00000000,0.000000;
filters=unsharp2=1,3.000000;
I'll either leave the parameters out completely, and at best, try coping
the Picasa params as is, just as a reference. Some clever nut can have a
go at converting them later on using the DB or something!
I'll let you know how I go. I have to resurrect Eclipse and Java now. I
had a quick look at writing a Kipi plug-in, but I couldn't work out the
language and find doco on how to work with it. I probably need to look
harder.
Cheers,
Simon
