[Bug 276480] New: wish: add support to zoom images in the slideshow

https://bugs.kde.org/show_bug.cgi?id=276480

           Summary: wish: add support to zoom images in the slideshow
           Product: digikam
           Version: 1.9.0
          Platform: Debian unstable
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           1.9.0 (using KDE 4.6.4)
OS:                Linux

I very much like the digikam slideshow. It is amazingly fast, even for big
image files. I guess that digikam uses preview versions of the image for that.

What I really miss is the possibility to zoom in/out in the slideshow. It would
be very good to support zooming in the slideshow.

Reproducible: Always

Steps to Reproduce:
Open a slideshow in digikam.

Actual Results:  
No zooming support in the slideshow.

Expected Results:  
Should support zooming in the slideshow.

Do you talk about slideshow from digiKam core or Advanced SlideShow from
kipi-plugins (last one is based on OpenGL)

Not sure. I'm talking about the slideshow which is launched by pressing F9 in
digikam, or by browsing "View" -> "Slideshow" -> "All" in the menu.

Thanks for the great work on this wonderful software!

use main digiKam image preview cache, and play video files.

Created attachment 89098

SlideImage class using preview widget

Implementation is not perfect. There is no fit to screen support for small
image. image navigation is broken using mouse wheel and keyboard shortcuts must
be review
