xdbedizzy is a demo of DBE creating a double buffered spinning scene.


-display host:dpy
 This option specifies the X server to contact.

 Redirects the PDL (Printer Desktoption Language, usually Postscript, PDF, PCL, etc.) stream to the specified file.
-numpages count
 Number of pages to print. Default is 5.
-delta dlt
 Delta value used to rotate the scene for each frame (video output) or page (printer output).
-class visclass
 Name of visual to choose. Valid values are TrueColor, DirectColor, PseudoColor, StaticColor, Grayscale, StaticGray
-depth depth
 Depth of visual to use.
-visid visualid
 Visual ID to use (ignore -class, -depth).
-list List double buffer capable visuals.
-nodb Single buffer (ignore -class, -depth, -visid).
-help Prints usage and exists.
-speed value
 Defines the time to delay between frames as delay=2sec/speed. Default value is 20. This option is ignored in print mode.
-sync Use synchronous X connection.
-spokes value
 Specify number of spokes to draw. The default value is 12.
