Equality Operator

Summary

Determines whether two AnnSize structures are equal.

Syntax

C++

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

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

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

Parameters

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

right
The AnnSize 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 sizes have different units, comparison will be done after temporarily converting both to a common unit.

Example

This example creates a size in inches, converts it to pixels, then makes sure the two sizes are still equal.

using Leadtools; 
using Leadtools.Annotations; 
 
public void AnnSize_OperatorEquals() 
{ 
   // set up a new unit converter with 96 DPI 
   AnnUnitConverter converter = new AnnUnitConverter(96, 96); 
 
   AnnSize inches = new AnnSize(1.5F, 2f, AnnUnit.Inch); 
   AnnSize pixels = new AnnSize(inches.ConvertTo(converter, AnnUnit.Pixel).ToSizeF(), 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 s As String 
 
   ' should say true 
   s = String.Format("Should say True: inches == pixels is {0}", AnnSize.op_Equality(inches, pixels)) 
   MessageBox.Show(s) 
 
   ' should say false 
   s = String.Format("Should say False: inches != pixels is {0}", AnnSize.op_Inequality(inches, pixels)) 
   MessageBox.Show(s) 
End Sub
