KSnapshot grabs an image of your entire desktop immediately after it is started, but before it displays itself on screen. This allows you to quickly create full-desktop screenshot images.
The snapshot taken by KSnapshot is displayed in the preview window, which is located in the upper right hand corner of the KSnapshot application window. Below is an example of the preview window from a typical full-desktop capture. Your preview will differ depending on what you have displayed on the desktop.
By left clicking on the preview window, it will be expanded to allow a full-scale view of the contents of the screen shot. Left clicking on the expanded preview will shrink the window back to it's normal size.
The snapshot may be saved by clicking on the Save button. The filename that the snapshot will be saved under appears in the Filename box. If multiple snapshots are taken, the filename is automatically incremented to prevent you from overwriting previous snapshots.
