Just connect :after the expose-event handler and use GDK or Cairo drawing API to draw :on the preview area. That's great, thanks (also to David Gowers for his response too). I'm still a relative novice with GTK- I learned what little I know in order to write this filter's dialog box- but I'll be taking a look at that. In the meantime, I've uploaded the linear unsharp mask filter code (first version) and some example images here:- http://home.freeuk.com/misacham/temp/mask.htm (Note (a) the images are fairly large and (b) Yes, I know the filter code is slow and could probably be *much* faster; one thing at a time). Like I said, I'd be very surprised if I was the first to think of this, but I wanted to play around with the idea on my own anyway. It's hardly a miracle cure for motion blur, but the results were pretty good; it certainly beats two-dimensional USM for that purpose. - triffid@xxxxxxxxxx _____________________________________________________________ Get your FREE OiNK-Mail ---> http://www.oink.co.uk Adopt an animal today and help support wildlife conservation ---> http://www.adoption.co.uk The Rainforests.
