Description

pset_marker_rep associates the polymarker index with the marker type, marker size scale factor, and polymarker color index values in the polymarker bundle table on the workstation specified by the workstation identifier.

A call to this function allows you to create or redefine an entry for the workstation polymarker bundle table. To determine the predefined bundle table entries, which are provided for all workstations of type OUTPUT and OUTIN, and which are derived from the workstation description table, run the program phigs_predef.

During structure traversal, the following occurs:

•When Digital PHIGS displays polymarker and polymarker 3 primitives, the current polymarker index entry in the PHIGS traversal state list refers to an entry in the polymarker bundle table.

•If Digital PHIGS cannot find the current polymarker index value in the polymarker bundle table on the specified workstation, it uses polymarker index 1.

•Digital PHIGS binds aspects to the primitives, as directed by the values of the corresponding ASFs (BUNDLED or INDIVIDUAL).
