Simulates a split-flap display, an old style of electromechanical
sign as seen in airports and train stations, and commonly used in alarm
clocks in the 1960s and 1970s.
- -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.
- -window
- Draw on a newly-created window. This is the default.
- -root
- Draw on the root window.
- -delay
number
- Per-frame delay, in microseconds. Default: 20000 (0.02 seconds).
- -speed
number
- Animation speed. 2.0 means twice as fast, 0.5 means half as fast.
- -width
number
- Columns of the display. Default: 22.
- -height
number
- Rows of the display. Default: 8.
- -mode clock12
- Display a 12-hour clock.
- -mode
clock24
- Display a 24-hour clock.
- -front |
-no-front
- When spinning, never spin all the way around or upside down: always face
mostly forward so that the text is easily readable. This is the
default.
- -no-front
- Allow spins to go all the way around or upside down.
- -wander |
-no-wander
- Whether the object should wander around the screen.
- -spin
- Which axes around which the text should spin. The default is
"XYZ", meaning rotate it freely in space. "-spin
Z" would rotate the text in the plane of the screen while not
rotating it into or out of the screen; etc.
- -wireframe |
-no-wireframe
- Render in wireframe instead of solid.
- -fps | -no-fps
- Whether to show a frames-per-second display at the bottom of the
screen.
- 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.
