13
15 The gltext program draws some text spinning around in 3D, using a font
16 that appears to be made of solid tubes.
17
19 gltext accepts the following options:
20
21 -window Draw on a newly-created window. This is the default.
22
23 -root Draw on the root window.
24
25 -install
26 Install a private colormap for the window.
27
28 -visual visual
29 Specify which visual to use. Legal values are the name of a
30 visual class, or the id number (decimal or hex) of a specific
31 visual.
32
33 -text string
34 The text to display. This may contain newlines, but it
35 shouldn't be very long. The default is to display the machine
36 name and OS version.
37
38 This may also be a format string acceptable to date(1) and
39 strftime(3), in which case, it will be updated once a second.
40 So to make this program display a spinning digital clock, you
41 could do this:
42 gltext -text "%A%n%d %b %Y%n%l:%M:%S %p"
43 To include a literal `%', you must double it: `%%'.
44
45 See the man page for strftime(3) for more details.
46
47 -program command
48 The given program is run, and its output is displayed. If
49 specified, this overrides -text. The output of this program
50 will be repeatedely displayed, with new pages of text shifting
51 in every few seconds. Lines should be relatively short. You
52 might try:
53 -program 'xscreensaver-text --cols 20'
54
55 -maxlines
56 Set the number of lines of text to display. By default, gltext
57 will print 8 lines of text at a time. Use this option to
58 increase or decrease that number. Be aware that gltext is
59 designed to work with a fairly small amount of text, so setting
60 this value too high might result in slow performance or strange
61 behaviour stemming from buffer overflows. Increase at your own
62 risk.
63
64 -mono Display the text in a monospace font. Default is a variable-
65 width font.
66
67 -no-mono
68 Display the text in a variable-width font. This is the
69 default.
70
71 -wander Move the text around the screen. This is the default.
72
73 -no-wander
74 Keep the text centered on the screen.
75
76 -wander-speed
77 Sets the speed at which the text wanders around. Default is
78 0.02.
79
80 -spin Which axes around which the text should spin. The default is
81 "XYZ", meaning rotate it freely in space. "-spin Z" would
82 rotate the text in the plane of the screen while not rotating
83 it into or out of the screen; etc.
84
85 -no-spin
86 Don't spin the text at all: the same as -spin "".
87
88 -front When spinning, never spin all the way around or upside down:
89 always face mostly forward so that the text is easily readable.
90
91 -no-front
92 Allow spins to go all the way around or upside down. This is
93 the default.
94
95 -wireframe
96 Render in wireframe instead of solid.
97
98 -fps Display the current frame rate, CPU load, and polygon count.
99
100 -scale Sets the scale at which the text is rendered. Bigger values
101 will result in bigger text; smaller values will result in
102 smaller text. The default value is 0.01.
103
105 DISPLAY to get the default host and display number.
106
107 XENVIRONMENT
108 to get the name of a resource file that overrides the global
109 resources stored in the RESOURCE_MANAGER property.
