Hi,

One of the nicest effects on iPhoto on OSX is the Zoom and Pan feature when viewing the images. It basically means that nothing is stationary and that transitions must blend on moving images.

The iPhoto version zooms in to some images and out from others, I'm not sure if this is a one in/one out basis. I know that you can pick focus points to zoom in to/out from etc on iDVD if you are making a professional slideshow for burning.

It is a really nice feature and it would be brilliant if kipi plugins could support this.

As another point (tho' this should be a separate bug). If iPhoto detects dual head, it will use both screens really nicely. Say you have 6 photos in your collections. Photo 1 will appear on Screen 1 and Photo 2 on Screen 2. Upon transition, Screen 1 shows Photo 3 and Screen 2 shows Photo 4. Next transition Screen 1 shows Photo 5, Screen 2 shows Photo 6 etc. etc. It was a really pleasent surprise that they'd thought of this when my mate connected an extra monitor to his iBook the other day. It would be great if the kipi slide show supported this too.

All the best, and thanks for the good work.

I am reliably informed that this is called the Ken Burns Effect.

I guess this would be like the GLSlideshow screensaver from xscreensaver? Yeah, that would rock :-)

This is a KDE screensaver implementing this effect.
