Options
squiral 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.
-
--mono -
If on a color display, pretend we're on a monochrome display.
-
--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.
-
--fill percent -
Specify the percent (0-100) of the screen which must be filled before the screen is cleared. 60-80 percent are good values.
-
--count number -
The number of squiralies. By default, the screen width divided by 32.
-
--scale number -
Line thickness.
-
--delay usec -
The wait between steps. The default is 1000.
-
--disorder fraction -
The fraction of the time a squiraly will choose a new direction. The default is 0.005.
-
--handedness fraction -
The fraction of the time a squiraly will choose to enter lefthanded mode. 0.0 means exclusively right-handed behavior, 0.5 (the default) is a balance between the two, and 1.0 is exclusively left-handed behaviour.
-
--fps -
Display the current frame rate and CPU load.
Environment
