xanalogtv(6) XScreenSaver manual xanalogtv(6) NAME xanalogtv - Simulate reception on an old analog TV set SYNOPSIS xanalogtv [--display host:display.screen] [--window] [--root] [--window-id number][--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 sta- tic. The images that it uses will be grabbed from the portion of the screen un- derlying 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 xscreen- saver-settings(1) for more details. It looks best with a video input or your digital photo collection. OPTIONS xanalogtv accepts the following options: --window Draw on a newly-created window. This is the default. --root Draw on the root window. --window-id number Draw on the specified window. --install Install a private colormap for the window. --visual visual Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. --fps Display the current frame rate and CPU load. ENVIRONMENT DISPLAY to get the default host and display number. XENVIRONMENT to get the name of a resource file that overrides the global re- sources stored in the RESOURCE_MANAGER property. XSCREENSAVER_WINDOW The window ID to use with --root. X RESOURCES 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.
