xanalogtv - Simulate reception on an old analog TV set
xanalogtv [-display host:display.screen] [-window] [-root] [-install]
[-visual visual] [-cycle] [-no-cycle]
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.
xanalogtv accepts the following options:
-window Draw on a newly-created window. This is the default.
-root Draw on the root window.
Install a private colormap for the window.
Specify which visual to use. Legal values are the name of a
visual class, or the id number (decimal or hex) of a specific
-cycle Cycle through all the available modes. This is the default.
Don’t cycle modes.
DISPLAY to get the default host and display number.
to get the name of a resource file that overrides the global
resources stored in the RESOURCE_MANAGER property.
Notable X resources supported include the following which correspond to
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.
