SYNOPSIS

fontglide [--display host:display.screen] [--window] [--root]
[--window-id number][--install] [--visual visual] [--delay usecs]
[--scroll] [--page] [--random] [--speed float] [--linger float]
[--program sh-command] [--font font-name] [--bw int] [--trails]
[--db] [--debug] [--fps]

DESCRIPTION

The fontglide program reads text from a subprocess and puts it on the
screen using large characters that glide in from the edges, assemble,
then disperse. Alternately, it can simply scroll whole sentences
from right to left.

OPTIONS

fontglide 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.

--delay usecs
The delay between steps of the animation, in microseconds:
default 10000.

--page With this option, a page full of text will glide in, and
disperse.

--scroll
With this option, sentences will scroll by from right to
left.

--random
The default is to pick randomly between --page and --scroll.

--speed float
How fast to animate; 2 means twice as fast, 0.5 means half as
fast. Default 1.0.

--linger float
How long to leave the assembled text on the screen in --page
mode; 2 means twice as long, 0.5 means half as long. Default
1.0. (The more words there are on the screen, the longer it
lingers.)

--program sh-command
The command to run to generate the text to display. This
option may be any string acceptable to /bin/sh. The program
will be run at the end of a pipe, and any words that it
prints to stdout will end up on the window. (Whitespace and
line breaks are ignored.) If the program exits, it will be
launched again after we have processed all the text it
produced. Default: xscreensaver-text(6).

--font string
The base font pattern to use when loading fonts. The default
is to search for any Latin1 scalable proportional fonts on
the system. Once a base font is selected, it will be loaded
in a random size.

--bw int
How thick an outline to draw around the characters. Default
2 pixels.

--trails
Leave "vapor trails" behind the moving text. Default off.

--no-db Turn off double-buffering. It may be faster, but will
flicker.

--debug Draw some boxes showing character metrics, and print the name
of the current font to stderr.

--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
resources stored in the RESOURCE_MANAGER property.

XSCREENSAVER_WINDOW
The window ID to use with --root.
