As shipped in IRIX 6.5.22. Added in IRIX 6.5.19.
NAME dtscreen - the SGI Common Desktop Environment animated screen savers SYNOPSIS dtscreen [ -display dsp ] [ -delay usecs ] [ -batchcount num ] [ -saturation value ] [ -nice nicelevel ] [ -mode mode ] DESCRIPTION The dtscreen client supports the following key tasks. - Draws an animated image on a provided window id(s). - Does not assume the size of the provided window(s). - Provides a set of selectable animated images. - Animation parameters such as nice, speed, number and saturation may be specified. The dtscreen client provides the default screen saver animations for the desktop. When launched, it will query the desktop using the API for the set for window ids on which to draw. These window ids could be the cover windows created by the session manager for session lock, or a window imbedded in the style manager's session lock customization dialog. Once obtained, the dtscreen client will proceed to draw in these windows using the specified options. If dtscreen cannot obtain the set of window ids, it will create its own. Normally, the dtscreen client will be invoked directly by the session manager, or by the style manager. Note that the Session Manager, dtsession, is responsible for locking the session and prompting for a password to unlock. The session manager may launch the dtscreen client to provide screen saver animations during session lock. Refer to the session manager specification for resources controlling the launching of screen savers by the session manager. The style manager may launch the dtscreen client to provide a preview of a screen saver animation during customization. Refer to the style manager specification for information on how to integrate a screen saver client such as dtscreen into the desktop. The dtsession client provides a selectable set of animations. These are: hop Hopalong iterated fractals. life Conway's game of life. qix Spinning lines. image Random bouncing image. swarm Swarm of bees. rotor Rotor pyro Fireworks. flame Cosmic Flame Fractals. worm Wiggly Worms. random Random mode. The dtscreen client animations are based on xlock(1). OPTIONS -display dsp The display on which animations will be drawn. -delay usecs The delay option sets the speed at which a mode will operate. It simply sets the number of microseconds to delay between batches of "hopalong pixels", "qix lines", "life generations", "image blits", and "swarm motions". -batchcount num The batchcount option sets the number of things to do per batch to num. In qix mode this refers to the number of lines rendered in the same color. In hop mode this refers to the number of pixels rendered in the same color. In image mode this refers to the number of X logos on the screen at once. in swarm mode this refers to the number of bees. In life mode it means nothing. -saturation value The saturation option sets the saturation of the color ramp used to value. 0 is grayscale, 1 is very rich color and 0.4 is a nice pastel. -nice nicelevel The nice option sets the system nicelevel of the dtscreen process to nicelevel. -mode mode The mode option specifies which animation should be displayed. Values are: hop Hopalong iterated fractals. life Conway's game of life. qix Spinning lines. image Random bouncing image. swarm Swarm of bees. rotor Rotor pyro Fireworks. flame Cosmic Flame Fractals. worm Wiggly Worms. random Random mode. RETURN VALUE Exit values are: 0 Successful completion. >0 Error condition occurred. EXAMPLES dtscreen -mode swarm Display the swarm animation.
