ICogGeneralContourEllipticalArcSegmentIterator EllipseFraction Property

Cognex VisionPro 9.7

Returns/sets the fraction of the ellipse that passes through the start, mid and end points. For slight arcs, using roughly a quarter of the ellipse will usually provide good results. This property must be between 0 and 1 (exclusive).
