Description:

This is a KDE slide show screensaver which uses OpenGL for smooth zooming and crossfades. It has a simular feel to that of the MacOS X slideshow screensaver. Note that since this uses OpenGL textures for the images, you will need significant amounts of texture memory on your card for this to work well (especially for large images).

I would appreciate any _constructive_ input. I changed some of the features of the screensaver: The images used to have a vignette effect, and you could select the size of the image; now the image is always sized so that it fills the screen. Which is preferable? Should it be an option? Does the incremental jpeg loader work? Does it eliminate the lag between images?




Changelog:

- Added support for png images. They are loaded incrementally just like the jpegs, so skipping shouldn't be a problem. please report any problems.

- Stability improvements. Works on both greyscale and color jpeg's now (before it would crash on greyscale jpegs). Gracefully handles unmounting of drives which images are stored on (i.e. it doesn't crash when it can't read an image). Added an option to display the image name in the lower left hand corner. Also, the screensaver no longer always zooms towards the center of an image. It can zoom to any portion of the image, but gives preference to the top half for portrait oriented images (since that is where the center of focus normally resides in portraits). Didn't update the preview cause I'm too lazy.

- Added line to link to libjpeg. For some reason it worked on my machine without it.

- Image directory selection will now traverse into any subdirectories up to depth 1. This means you can effectively use multiple directories for source images by creating a directory with symlinks to your image directories.

- Much faster load up time, much smaller memory footprint, and uses much less CPU time than before.

- Implemented a incremental jpeg loader that (hopefully) prevents jerkiness between images. Movement should be smooth, unless of course, you set the delay time to something very small and your machine cannot finish loading the next image before it is due for display.

 Phenom

This thing is awesome! after finally getting it to compile it took a bit of work to get it to work in mdk. I'd make an rpm but i'm sure tex'll find his way over and package it in time. but in the few hours it will take for this to happen here's what i did to get it to work on mdk 9.1:
1) i passed --prefix=/usr to the configure script with this command
  • ./configure --prefix=/usr
    and then did make both as a normal user
    2) then for make install i did this
  • su -c "make install"
    3) After the make install step i entered this command
  • su -c "ln -s /usr/share/apps/kscreensaver/ScreenSavers/kslidesavergl.desktop /usr/share/applnk/System/ScreenSavers/kslidesavergl.desktop"
    then you just enter your root password so that the command works. Then go into the KDE control center and Voila!
    Great work wjarosz, keep it up.

    Please make debian .debs available, this way it could be included in Knoppix (www.knoppix.net)

    I unfortunately don't have any experience in that and don't have time to teach myself at the momement. But anyone is of course welcome to make a .deb out of this and release it under the GPL.

     Very nice

    Very nice work. Has anyone experienced the following problem with this screensaver. When clicking on the test button to test the screensaver and then quiting it (clicking on mouse button etc), the kslideshow.kss process still stays running. Clicking test several times always leaves a new process running and if you press cancel on screensaver configuration dialog, they still keep on running, until I manually kill them.

    Do you have libGLU installed? They will either be provided by Mesa or whatever GL driver you may be using. Note that the rpm that is currently available on kde-look is not up to date with the newest version of the screensaver that I uploaded today. (AFAICT).

    you have to install the following package:

    "libMesaGLU1-devel"

    for problems like this, try:

    $ urpmf glu.h

    the result is something like this:

    libMesaGLU1-devel:/usr/X11R6/include/GL/glu.h

    (urpmf is comfortable to find out, from which package a file comes from)

     Widget Set

     
     by KhanReaper on: Apr 25 2003
     
    Score 50%

    In the screenshot provided for this project, I see a widget set of which I have little familiarity in terms of KDE styles.

    From what I can ascertain, it appears similar to the GTK-2 widget set entitled "Wonderland" as seen here:

    http://art.gnome.org/show_theme.php?themeID=274&category=gtk2

    Since my question predicates itself upon the assumption that this screensaver utilize KDE's architecture, I assume that KDE provides these widgets for the screensaver.

    If I may inquire, what KDE style did the author use to achieve this Wonderland-esque facade?

    Thank you.

    That is the Bluecurve theme which is the default theme for both Gnome and KDE in Redhat 8.0/9. I'm pretty sure you can get repackaged version for other distros somewhere on this site, or you could look into freecurve or qtcurve.

    How do you like Plasma 5?
     The best KDE Desktop ever.
     Definitely a nice improvement.
     Not decided yet. Haven't tried it yet.
     I do not like some of the changes.
     KDE is taking the wrong way.
     I am still sticking with KDE 3.5.
     I have no opinion, but wanted to vote anyway.
