HARDCOPY /DEVICE

        [GTVL\]HARDCOPY [/DEVICE Name [Attributes]]

    The /DEVICE option argument specifies which type of device will be used.
    The  other arguments passed after the device name can modify the harcopy
    attributes. Several attributes can be combined. Allowed devices and  at-
    tributes are:

      PS  (PostScript):  the plot is automatically rotated and scaled on the
              hardcopy physical page.
        GREY  PostScript with fixed greyscale transfer function for  bitmap.
        COLOR PostScript  with user controlled color transfer function. This
              is the default.
        FAST  PostScript with hardware pen thickness handling.  Clipping  of
              wide pens may be inaccurate. This is not the default.

      EPS (Encapsulated PostScript): As PS, with the BoundingBox is computed
              from the plot boundaries rather than from the Plot Page  size.
              The  plot is NOT rotated neither scaled to the hardcopy physi-
              cal size by default. Use the option /FITPAGE  to  enable  this
              feature.
        GREY  Same as PS.
        COLOR Same as PS.
        FAST  Same as PS.

      PNG (Portable Network Graphics): create a bitmap representation of the
              GreG plot. The size of the PNG can be tuned  with  the  option
              /GEOMETRY.
        GREY  Same as PS
        COLOR Same as PS
        WHITE PNG  with  white  background and black foreground. This is the
              default.
        BLACK PNG with black background and white foreground.
        TRANSPARENT PNG with transparent background. This is  not  exclusive
              with WHITE and BLACK attributes, i.e. "TRANSPARENT BLACK" cre-
              ates a PNG with transparent background and  white  foreground.
              Transparency is not activated by default.
        CROPPED the GreG plot is expanded to fit exactly to the best PNG di-
              mensions, and the other PNG dimension is shrinked to leave  no
              margin.

      SVG  (Scalable  Vector Graphics): create a vectorial representation of
              the GreG plot (except for images) in the SVG format.
