SlideShow (GL)

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?

- 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.
