Equality Operator (AnnPoint)






The AnnPoint structure on the left side of the equality operator.
The AnnPoint structure on the right side of the equality operator.
Tests whether two AnnPoint structures are equal.
Syntax
public bool operator ==( 
   AnnPoint left,
   AnnPoint right
)
'Declaration
 
Public Operator =( _
   ByVal left As AnnPoint, _
   ByVal right As AnnPoint _
) As Boolean
'Usage
 

            

            
public:
bool operator ==( 
   AnnPoint left,
   AnnPoint right
)

Parameters

left
The AnnPoint structure on the left side of the equality operator.
right
The AnnPoint structure on the right side of the equality operator.

Return Value

This operator returns true if left and right have equal X and Y values; otherwise false.
Remarks
If the two points have different units, the comparison will be done after temporarily converting both to a common unit.
Example

This example creates a point in inches, converts it to pixels and then makes sure the 2 points are still equal.
