Download New Wipes
This feature allows you to download and install files that can be used as Wipe files in the Wipe transition. These files are greyscale images in the pgm format.
If you have your own wipe files that you would like to share with the community you can upload them to store.kde.org which should make them available from this Download New Wipes function.
