Package:           kdvi
Version:           KDE 3.0.0 
Severity:          wishlist
Installed from:    Mandrake RPMs
Compiler:          Not Specified

It would be interesting if kdvi could be used for slides presentation a la powerpoint.
New extension of dvi have been developped to do interactive animated presentations that are called "active dvi". See http://pauillac.inria.fr/advi/
It's really nice!

Active DVI has 2 other interesting features:

1. like xdvi, it responds to SIGUSR1 (I believe) by refreshing the current page. This is actually easy to obtain with kdvi, using the appropriate DCOP message. Don't know about the relative speed though.

2. when refreshing, unlike xdvi, it does not first clear the page, then paint a new page; rather, it paints to an off-screen pixmap, then copies the pixmap to screen. Result: flicker-free refreshes.

Both features are useful in conjunction with Whizzytex, which provides "instant preview" under Emacs. For what it's worth, I should also point out that right now xdvi and advi are both quite a bit faster (e.g. when rendering a single page) than kdvi. 

I wish I had some time to look into these matters---I use Kile and Kdvi all the time. Right now I can only point them out, perhaps for future memory... sorry!

kdvi is no longer maintained since KDE SC 4, and its functionality is replace by okular.  If the issue in this report still exists in or apply to okular in KDE SC 4.10.5 or higher, please reassign the report to okular product or create a new report against okular.
