NAME
       GSVP  (Set viewport) - establishes a rectangular subspace of normalized device coordinates
       space. Calls to GSVP are discouraged with NCAR Graphics. Instead, use the  SET  subroutine
       because SET also supports mirror imaging and log scaling of axes.


SYNOPSIS
       CALL GSVP (TRNUM, XMIN, XMAX, YMIN, YMAX)


C-BINDING SYNOPSIS
       #include <ncarg/gks.h>

       void gset_vp(Gint tran_num, const Glimit *vp_limits);


DESCRIPTION
       TRNUM       (Integer,  Input)  -  A  normalization  transformation  number.  The number of
                   available transformations is implementation specific.  In  the  case  of  NCAR
                   GKS-0A, two normalization transformations are provided:

                   0      Selects  the  identity  transformation  in  which  both  the window and
                          viewport have the range of 0. to  1.  in  both  coordinate  directions.
                          This  is  the  default normalization transformation for GKS. It is also
                          fixed within GKS; that is, it is illegal to call GSVP with TRNUM = 0.

                   1      A normalization transformation in which the viewport is defined by XMIN
                          to XMAX and YMIN to YMAX.

       XMIN        (Real, Input) - The left horizontal coordinate of the viewport.

       XMAX        (Real,  Input) - The right horizontal coordinate of the viewport.  0. ≤ XMIN <
                   XMAX ≤ 1.

       YMIN        (Real, Input) - The bottom vertical coordinate of the viewport.

       YMAX        (Real, Input) - The top vertical coordinate of the viewport.  0. ≤ YMIN < YMAX
                   ≤ 1.

       Defaults:   TRNUM = 0, XMIN = 0.0, XMAX = 1.0, YMIN = 0.0, YMAX = 1.0


ACCESS
       To use GKS routines, load the NCAR GKS-0A library ncarg_gks.
