Public Overridable Function HitTest( _ ByVal point As LeadPointD, _ ByVal hitTestBuffer As Double _ ) As Boolean
public virtual bool HitTest( LeadPointD point, double hitTestBuffer )
-(BOOL) hitTest:(LeadPointD)pt buffer:(double)buffer;
public boolean hitTest( LeadPointD point, double hitTestBuffer )
function Leadtools.Annotations.Core.AnnObject.HitTest( point , hitTestBuffer )
hitTestBuffer is used to make the test point "bigger" to compensate for errors and provide smoother hit-testing. For example, if buffer is 2, a square with a length of 4 units around the test point will be used to perform the hit-testing.
By default, an annotation object will return true if hit-testing was satisfied. Derived objects can override this method to fine tune the return value.
