1 SIXEL

	This program will convert a ReGIS graphics file (such as one produced
	by Datatrieve) and produce a SIXEL graphics file which is suitable for
	printing on an appropriate printer (LA50, LA100, LN03, etc.).Since the
	SIXEL conversion is a hardware function of a graphics terminal, the
	program requires the use of a REGIS terminal.  This device is defined
	by the logical DISPLAY$DEVICE.  For an interactive terminal, therefore,
	a definitions such as the following should be made.

		$ DEFINE DISPLAY$DEVICE TT:

	If there is no logical translation for DISPLAY$DEVICE, the program
	performs the above definition on the users behalf.

	In addition, DISPLAY$DEVICE should be set to REGIS; the program will
	abort If this characteristics is not set.

	The specified ReGIS file is opened and displayed on the screen of
	DISPLAY$DEVICE.  The required sequences are sent to this device which
	set graphics to host, enter regis, and initiate hardcopy output.
2 Examples
		$ SIXEL/GRAPH_TYPE=<option>  regis-file-spec  sixel-file-spec

		$ SIXEL/GRAPH_TYPE=<option>/LOCAL/RESET  regis-file-spec
2 /GRAPH_TYPE
			/GRAPH_TYPE=<option>

	An optional qualifier, /GRAPH_TYPE can take any of three options.
	The options are EXPANDED, ROTATED, and COMPRESSED.  If the EXPANDED
	option is selected, the sixel output produced will be approximately
	12x8 inches.  The ROTATED option will produce output approximately 8x12
	inches and rotated 90 degrees; this will fit on standard 8 1/2 x 11
	paper such as that typically loaded into an LA50 printer.  Finally,
	the COMPRESSED 	option will produce a graph approximately 6x3 inches.
2 /LOCAL

	If the /LOCAL qualifier is present, SIXEL output is directed to a
	printer attached to DISPLAY$DEVICE.  If this qualifier is specified no
	sixel-file-spec is allowed.
2 /RESET

	If the /RESET qualifier is present, DISPLAY$DEVICE will be set to
	COMPRESSED mode before exiting otherwise it will be left in the mode
	specified by the /GRAPH_TYPE option.
