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 hor-
izontal 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 ran-
dom file on disk, as indicated by the grabDesktopImages, grabVide-
oFrames, 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.
