Methods

CompareTo

#
public int CompareTo(ISnapElement other)
Compares the current instance with another object of the same type and returns an integer that indicates whether the current instance precedes, follows, or occurs in the same position in the sort order as the other object.
Parameters:
other (ISnapElement)An object to compare with this instance.

Zero This instance occurs in the same position in the sort order as other. Greater than zero This instance follows other in the sort order.

Snap

#
public abstract bool Snap(double x, double y, out double snapX, out double snapY)
Snap a point to this element.
Parameters:
x (double)Point x coordinate to snap.
y (double)Point y coordinate to snap.
snapX (out double)Snapped x coordinate.
snapY (out double)snapped y coordinate.
Returns: True if (x, y) got mapped to a different (x', y').
