Description Ian Hubbertz 2010-06-19 01:44:16 UTC

Version:           1.3.0 (using KDE 4.4.2) 
OS:                Linux

This is a more complicated wish, so as an introduction a short "motivation" for it:

I'm currently sorting / rating photos of a long vacation and thinking about how to present them. Due to the large amount of photos (>6500), I probably will present only 4stars+ photos to most of my friends. Some interesting photos so may be skipped, as they are rated 3 stars only.

Thus it would be nice to have a slideshow that looks at the rating and shows only the configured value (e.g. at least 4 stars), but shows lower rated (e.g. 3 stars only) photos in background, so they can be clicked and enlarged, too.
So, if someone finds a particular photo interesting, "nearby" fotos can easily be shown, too.

Using mouse or keyboard to get the next image should show the next high-rated image.

If you have a look at the Windows Vista slideshow, there are some "themes" that shows one large and more smaller photos on the screen at the same time.

Such a design would be good for implementing my whish.

This would also introduce some interactivity to the slideshow, so the mode may be called "presenter mode" instead of slideshow.

Reproducible: Didn't try

Simple mockup of the "Advanced slideshow" feature

Mockup of the suggested slideshow feature what would show lower rated (3) photos aside of the asked rated photos (4-5) so presenter can any time pick one to show something what would otherwise being missed or what answers to watcher question.

Looks great.

And make me think of a first simple solution:

The default viewer is almost capable of doing this:

All what is needed is to add a hotkey to jump to the next (previous) image with at least n stars.

Then you could set the filter to e.g 3 stars and jump from one 4 (or 5) star image to another.


To get a presenter mode, of course some "polishing" would be nice, e.g. as shown in the mockup.

Even additional features (e.g. showing the marble-map as (transparent) overlay) could then be added nicely.

(Hotkey to show map overlay).

Ian,

What's about this file using last digiKam 4.2.0 ?

To only show all rated image while slideshow, go to Labels view from left sidebar, select right label, and press F9. All images will same label will be presented to screen.

This work perfectly using current implementation from git/master.

About arrow keys support, see bug #339051
