Description

pinq_pred_edge_rep returns values for the following:

•Edge flag value

•Edge type

•Edge width scale factor

•Edge color index

If the specified depth cue index is not in the depth cue table on the specified workstation, and the specified type of returned value is REALIZED, the function returns the representation for the depth cue index 1.
