Description

PSEDFG specifies the edge flag value.  Depending on the current edit mode, this function either inserts the new structure element directly after the element indicated by the pointer or replaces the element indicated by the pointer. The pointer then points to the new set edge flag element. 

During structure traversal, Digital PHIGS sets the current edge flag entry in the PHIGS traversal state list to the specified value.  If the current edge flag ASF entry is INDIVIDUAL, Digital PHIGS uses this value during the subsequent traversal of the following primitives:

•Fill area set

•Fill area set 3

•Fill area set with data

•Quadrilateral mesh with data

•Set of fill area set with data

•Triangle set with data

•Triangle strip with data

If the corresponding ASF is BUNDLED, the value has no effect. 

If Digital PHIGS is in immediate mode, it performs this function immediately, but the function does not create a structure element.
