fontglide - characters float onto the screen to form words  


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


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.  


fontglide accepts the following options:
Draw on a newly-created window. This is the default.
Draw on the root window.
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.
With this option, a page full of text will glide in, and disperse.
With this option, sentences will scroll by from right to left.
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(1).
-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.
Leave "vapor trails" behind the moving text. Default off.
Turn off double-buffering. It may be faster, but will flicker.
Draw some boxes showing character metrics, and print the name of the current font to stderr.


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.
