13 xanalogtv shows a simulation of an old TV set showing test patterns and
14 any other images you have provided. It reproduces a wide range of TV
15 reception bummage: snow, bloom, ghosting, and loss of vertical and hor‐
16 izontal sync. It also simulates the TV warming up. It will cycle
17 through 12 channels, some with images you give it, and some with color
18 bars or nothing but static.
19
20 The images that it uses will be grabbed from the portion of the screen
21 underlying the window, or from the system's video input, or from a ran‐
22 dom file on disk, as indicated by the grabDesktopImages, grabVide‐
23 oFrames, and chooseRandomImages options in the ~/.xscreensaver file;
24 see xscreensaver-demo(1) for more details. It looks best with a video
25 input or your digital photo collection.
