     OUTPUT TYPE

     Raster    The "Output Type" toggles between "vector" and
               "raster".  When the Output Type is set to "ras-
               ter", Xprism3 simply sends a screen dump of  the
               workspace directly to "vlaser"; in this case, the
               Imagen pane of the Output subform may be con-
               sidered simply to be a convenient user interface
               to "vlaser". If desired, one might replicate the
               operation of this pane WITH RASTER OUTPUT by sav-
               ing 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 RAS-
               TER OUTPUT.

     Vector    Vector Output may also be referred to as "Quality
               Output" - 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 xprism3,
               vector output in ImPRESS still has some limita-
               tions:
               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 rectan-
               gles.
               d)  ANNOTATIONS have not yet been implemented with
               vector 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.
