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=
