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) Perl/PDL: Not available?

       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.
