Function Documentation

static void CheckArcPointForRubberbandConnection	(	LayerType *	Layer,
		ArcType *	Arc,
		PointType *	ArcPoint,
		bool	Exact
	)		[static]

Checks all visible lines which belong to the same group as the passed arc.

If one of the endpoints of the line lays inside the passed arc, the scanned line is added to the 'rubberband' list

[static]

Checks all visible lines.

If one of the endpoints of the line lays inside the pin, the line is added to the 'rubberband' list.

Square pins are handled as if they were round.

Speed and readability is more important then the few % of failures that are immediately recognized.
