NAME

plgvpd - Get viewport limits in normalized device coordinates

SYNOPSIS

plgvpd(p_xmin, p_xmax, p_ymin, p_ymax)

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.

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.
