NAME
       plgvpd - Get viewport limits in normalized device coordinates


SYNOPSIS
       plgvpd(p_xmin, p_xmax, p_ymin, p_ymax)


DESCRIPTION
       Get viewport limits in normalized device coordinates.

       Redacted form: General: plgvpd(p_xmin, p_xmax, p_ymin, p_ymax)

       This function is used in example 31.


ARGUMENTS
       p_xmin (PLFLT_NC_SCALAR(3plplot), output)
              Returned  value  of the lower viewport limit of the normalized device coordinate in
              x.

       p_xmax (PLFLT_NC_SCALAR(3plplot), output)
              Returned value of the upper viewport limit of the normalized device  coordinate  in
              x.

       p_ymin (PLFLT_NC_SCALAR(3plplot), output)
              Returned  value  of the lower viewport limit of the normalized device coordinate in
              y.

       p_ymax (PLFLT_NC_SCALAR(3plplot), output)
              Returned value of the upper viewport limit of the normalized device  coordinate  in
              y.
