NAME

xteevee - Simulate various TV problems

SYNOPSIS

xteevee [-display host:display.screen] [-window] [-root] [-install] [-visual visual] [-cycle] [-no-cycle] [-static] [-no-static] [-roll] [-no-roll] [-bars] [-no-bars]

DESCRIPTION

xteevee simulates various television problems, fondly re-creating the days when computers were fun and I spent my time with an Atari 400 hooked up to a black-and-white TV I found in someone's trash.

When run, xteevee picks a mode to display from the available options. If modes are explicitly set on the command-line, they over-ride the implicit options and will be choosen among exclusively. If modes are explicitly excluded from the command-line, the they are simply removed from contention.

The image that it manipulates 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.

See also xanalogtv(1) for a more sophisticated (but more graphics-intensive) implementation of this concept.

OPTIONS

xteevee accepts the following options:

-window: Draw on a newly-created window. This is the default.
-root: Draw on the root 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.
-cycle: Cycle through all the available modes. This is the default.
-no-cycle: Don't cycle modes.
-static: Explicitly select the "static" mode.
-no-static: Explicitly forbid the "static" mode.
-roll: Explicitly select the "vertical roll" mode.
-no-roll: Explicitly forbid the "vertical roll" mode.
-bars: Explicitly select the "color bars" mode.
-no-bars: Explicitly forbid the "color bars" mode.

ENVIRONMENT

DISPLAY: to get the default host and display number.
XENVIRONMENT: to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.

X RESOURCES

Notable X resources supported include the following:

static, roll and bars are booleans, defining which modes are to be implicitly available if xteevee is run without command-line mode selections. cycle is a boolean, defining if xteevee should cycle through each available mode or pick one and stick with it. delayMode and delayBetween are integers, defining how long each mode should be displayed and how long the time between them should be if cycle is on. staticSignal is an integer, defining the strength of the signal during the "static" mode, as a percentage.

BUGS

xteevee should simulate more TV problems.
