Syntax

Java

Objective-C

WinRT C#

C++

protected virtual LeadPointD[] GetRotationReferencePoints()

Protected Overridable Function GetRotationReferencePoints() As Leadtools.LeadPointD()

protected virtual [Leadtools.LeadPointD[]](../l/leadpointd.md) GetRotationReferencePoints()

@property (nonatomic, strong, readonly, nullable) LTLeadPointCollection *rotationReferencePoints

protected LeadPointD[] getRotationReferencePoints()

 function Leadtools.Annotations.Designers.AnnEditDesigner.GetRotationReferencePoints()

protected:  
   virtual array<LeadPointD^>^ GetRotationReferencePoints()

Return Value

The two reference points used to keep the rotation center and gripper at an even distance when the object is moved in annotation coordinates.

Remarks

By default, the AnnEditDesigner returns the first two points found in the AnnObject.Points collection of the TargetObject. The designer then uses these reference points to keep the rotate center and gripper at an even distance when the object is moved.

Derived classes can override GetRotationReferencePoints to return any two points to use as the reference points. Usually these are the points at the "top-left" and "bottom-right" edge of the object.
