LEADTOOLS Annotations (Leadtools.Annotations assembly)

CalculateRotateAngle Method (AnnObject)

Show in webframe
Example 





Returns the rotate angle of an AnnObject in degrees.
Syntax
public virtual float CalculateRotateAngle()
'Declaration
 
Public Overridable Function CalculateRotateAngle() As Single
'Usage
 
Dim instance As AnnObject
Dim value As Single
 
value = instance.CalculateRotateAngle()

            

            
public:
virtual float CalculateRotateAngle(); 

Return Value

The rotate angle of the AnnObject in degrees.
Remarks
The rotate angle returned is formed by the object and the horizontal. A positive value represents a clockwise rotation, and a negative value represents a counter-clockwise rotation. Many objects do not have a rotate angle (i.e. AnnPolylineObject) and will therefore return 0 degrees. For rectangular objects (objects derived from AnnRectangleObject), the angle computed is formed by the top edge of the object and the horizontal. For more information, refer to New Annotation Features of Version 14.5.

   Dim s As String = String.Format("The selected {0} has a rotate angle of {1}", obj.GetType().ToString(), angle)
   MessageBox.Show(s)
End Sub
