The graPHIGS Programming Interface: ISO PHIGS Subroutine Reference



Use Set Edge Flag to insert a Set Edge Flag structure element into the open structure following the element pointer or replace the element pointed at by the element pointer with a Set Edge Flag structure element, depending on the current edit mode.

This structure element indicates whether or not the graPHIGS API draws the edge of subsequent polygon primitives during structure traversal. The graPHIGS API uses the specified value if the aspect source flag value is set to INDIVIDUAL (Set Individual ASF).

The traversal default for edge flag is OFF.

If the workstation does not support the specified edge flag value or if the specified value is outside the allowable range, then the edge flag defaults to OFF.
