     OUTPUT TYPE

     Raster
          The "Output Type" toggles between "vector" and "ras-
          ter".  When the Output Type is set to "raster", Xprism2
          simply sends a screen dump of  the workspace directly
          to "vlaser"; in this case, the Imagen pane of the Out-
          put subform may be considered simply to be a convenient
          user interface to "vlaser". If desired, one might
          replicate the operation of this pane WITH RASTER OUTPUT
          by saving the xprism workspace as a screen dump (see
          the help provided on the "Files" pane of the Output
          subform), and then sending the screen dump to the
          imagen printer using the Khoros routine,"vlaser".
          NOTE: IF YOU ARE USING OVERLAYS, YOU MUST USE RASTER
          OUTPUT.

     Vector
          Vector Output may also be referred to as "Quality Out-
          put" - certain operations are done so that the plot
          that is printed out will have smoother lines and a
          clearer rendering than is possible on the display. In
          general, vector output is always the method of choice.
          Text and fonts look far superior with vector output,
          lines are smooth, and the graphics workspace in general
          looks more refined on paper than it can on the screen.
          However, since it is one of the newest features of
          xprism2, vector output in ImPRESS still has some limi-
          tations:
          a)  LINE TYPES have not been implemented yet - all line
          types will look SOLID.
          b)  MARKER TYPE CIRCLE may not come out.
          c)  MESH PLOTS on ImPRESS do not come out nicely, as
          ImPRESS has no way to represent a polygon -- all there
          is to work with are squares and rectangles.
          d)  ANNOTATIONS have not yet been implemented with vec-
          tor output - they cannot be output with vector at all.

     Output to Printer vs. Output to File

          If one wishes to send the xprism workspace directly to
          an available imagen printer, fill in the "Printer"
          parameter box with the name of your local imagen
          printer.  When the user hits return, the workspace will
          be sent straight to the specified printer.  On the
          other hand, one may not have direct access to a imagen
          printer, but desire to use one on another system, for
          example.  To do this, one might first fill in the
          "Filename" parameter box with the name of a file to
          save the workspace in.  When the user hits return, the
          workspace is saved in the named file. This file may
          then be ftp'ed, mailed, etc. to the computer which is
          connected to the desired imagen printer, and then sent
          to that printer with a simple "lpr " command.
