Q3PolyLine_GetSegmentAttributeSet

You can use the Q3PolyLine_GetSegmentAttributeSet function to get the attribute set of a segment of a polyline.

TQ3Status Q3PolyLine_GetSegmentAttributeSet (
TQ3GeometryObject polyLine, 
unsigned long index, 
TQ3AttributeSet *attributeSet);

polyLine

A polyline.

index

An index into the vertices array of the specified polyline.

attributeSet

On exit, a pointer to an attribute set for the specified segment.

DESCRIPTION

The Q3PolyLine_GetSegmentAttributeSet function returns, in the attributeSet parameter, the set of attributes for a segment of a polyline. The segment is defined by the two vertices having indices index and index+1 in the vertices array of the polyline specified by the polyLine parameter. The reference count of the set is incremented.
