Equality Operator (AnnLength)

Summary

Tests whether two AnnLength structures are equal.

Syntax

C++

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

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

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

Parameters

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

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

Return Value

This operator returns true if

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

Remarks

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

Example

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

using Leadtools; 
using Leadtools.Annotations; 
using Leadtools.Codecs; 
using Leadtools.WinForms; 
 
public void AnnLength_OperatorEquals() 
{ 
   // set up a new unit converter with 96 DPI 
   AnnUnitConverter converter = new AnnUnitConverter(96, 96); 
 
   AnnLength inches = new AnnLength(1.5F, AnnUnit.Inch); 
   AnnLength pixels = new AnnLength(inches.Converted(converter, AnnUnit.Pixel), AnnUnit.Pixel); 
 
   string s; 
   // should say true 
   s = string.Format("This should be true: inches == pixels is {0}", inches == pixels); 
   MessageBox.Show(s); 
 
   // should say false 
   s = string.Format("This should be false: inches != pixels is {0}", inches != pixels); 
   MessageBox.Show(s); 
}
