Equality Operator

Summary

Tests whether two AnnPoint structures are equal.

Syntax

C++

public static bool ==( 
   AnnPoint left, 
   AnnPoint right 
)

  
Public Operator =( _ 
   ByVal left As Leadtools.Annotations.AnnPoint, _ 
   ByVal right As Leadtools.Annotations.AnnPoint _ 
) As Boolean

public: 
bool operator ==(  
   Leadtools.Annotations.AnnPoint left, 
   Leadtools.Annotations.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.

using Leadtools; 
using Leadtools.Annotations; 
 
public void AnnPoint_OperatorEquals() 
{ 
   // set up a new unit converter with 96 DPI 
   AnnUnitConverter converter = new AnnUnitConverter(96, 96); 
 
   AnnPoint inches = new AnnPoint(1.5F, 2f, AnnUnit.Inch); 
   AnnPoint pixels = new AnnPoint(inches.ConvertTo(converter, AnnUnit.Pixel).ToPointF(), AnnUnit.Pixel); 
 
   // should say true 
   string s; 
   s = string.Format("Should say True: inches == pixels is {0}", inches == pixels); 
   MessageBox.Show(s); 
 
   // should say false 
   s = string.Format("Should say False: inches != pixels is {0}", inches != pixels); 
   MessageBox.Show(s); 
}

Imports Leadtools 
Imports Leadtools.Annotations

   ' set up a new unit converter with 96 DPI 
   Dim converter As AnnUnitConverter = New AnnUnitConverter(96, 96) 
 
   Dim inches As AnnPoint = New AnnPoint(1.5F, 2.0F, AnnUnit.Inch) 
   Dim pixels As AnnPoint = New AnnPoint(inches.ConvertTo(converter, AnnUnit.Pixel).ToPointF(), AnnUnit.Pixel) 
 
   ' should say true 
   Dim s As String 
   s = String.Format("Should say True: inches == pixels is {0}", AnnPoint.op_Equality(inches, pixels)) 
 
   MessageBox.Show(s) 
 
   ' should say false 
   s = String.Format("Should say False: inches != pixels is {0}", AnnPoint.op_Inequality(inches, pixels)) 
 
   MessageBox.Show(s) 
End Sub
