NAME

       xanalogtv - Simulate reception on an old analog TV set

SYNOPSIS

       xanalogtv  [-display  host:display.screen] [-window] [-root] [-install]
       [-visual visual] [-cycle] [-no-cycle] [-fps]

DESCRIPTION

       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-demo(1) for more details. It looks best with a
       video input or your digital photo collection.

       xanalogtv accepts the following options:

       -window Draw on a newly-created window.  This is the default.

               visual.

       -fps    Display the current frame rate and CPU load.

ENVIRONMENT

       standard TV controls: analogTVTint, analogTVColor,  analogTVBrightness,
       and  analogTVContrast.  They range from 0 to 100, except for tint which
       is an angle between -180 and +180.
