Equality Operator

Summary

Tests whether two AnnRectangle structures are equal.

Syntax

C++

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

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

public: 
bool operator ==(  
   Leadtools.Annotations.AnnRectangle left, 
   Leadtools.Annotations.AnnRectangle right 
)

Parameters

left
The AnnRectangle structure on the left side of the equality operator.

right
The AnnRectangle structure on the right side of the equality operator.

Return Value

This operator returns true if left and right have equal Width and Height values; otherwise false.

Remarks

If the two rectangles have different units, the comparison will be done after temporarily converting both rectangles to a common unit.

Example

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

using Leadtools; 
using Leadtools.Annotations; 
 
public void AnnRectangle_OperatorEquals() 
{ 
   // set up a new unit converter with 96 DPI 
   AnnUnitConverter converter = new AnnUnitConverter(96, 96); 
 
   AnnRectangle inches = new AnnRectangle(1.5F, 2F, 3F, 4F, AnnUnit.Inch); 
   AnnRectangle pixels = new AnnRectangle(inches.ConvertTo(converter, AnnUnit.Pixel).ToRectangleF(), AnnUnit.Pixel); 
 
   string s; 
   // should say true 
   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); 
 
}

   Dim pixels As AnnRectangle = New AnnRectangle(inches.ConvertTo(converter, AnnUnit.Pixel).ToRectangleF(), AnnUnit.Pixel) 
 
   Dim s As String 
   ' should say true 
   s = String.Format("Should say True: inches == pixels is {0}", AnnRectangle.op_Equality(inches, pixels)) 
 
   MessageBox.Show(s) 
 
   ' should say false 
   s = String.Format("Should say False: inches != pixels is {0}", AnnRectangle.op_Inequality(inches, pixels)) 
   MessageBox.Show(s) 
 
End Sub
