       for any purpose.  It is provided "as is" without express or implied warranty.

xanalogtv shows a simulation of an old TV set showing  test  patterns  and  any  other  images  you  have
       provided. It reproduces a wide range of TV reception bummage: snow, bloom, ghosting, and loss of vertical
       and  horizontal  sync.  It also simulates the TV warming up. It will cycle through 12 channels, some with
       images you give it, and some with color bars or nothing but static.

       The images that it uses will be grabbed from the portion of the screen underlying the window, or from the
       system's  video  input,  or  from  a  random  file  on  disk,  as  indicated  by  the  grabDesktopImages,
       grabVideoFrames, and chooseRandomImages options in the ~/.xscreensaver file; see xscreensaver-settings(1)
       for more details. It looks best with a video input or your digital photo collection.

DISPLAY to get the default host and display number.

       XENVIRONMENT

               RESOURCE_MANAGER property.
