Description

pinq_line_rep queries the workstation state list and returns the line type, the line width scale factor, and the polyline color index.

If the specified polyline index is not in the polyline bundle table on the specified workstation, and the specified type of returned values is PINQ_REALIZED, Digital PHIGS returns the representation for polyline index 1. (See the Device Specifics Reference Manual for DEC GKS and DEC PHIGS for workstation-specific information.)
