Subtraction Operator (LogicalPoint)

Returns a LogicalPoint that results from subtracting the width and height of a LogicalSize structure from the X and Y coordinates of the LogicalPoint structure, respectively.

Syntax

Visual Basic
C#
WinRT C#
WinRT JavaScript
C++

public LogicalPoint operator -( 
   LogicalPoint point,
   LogicalSize size
)

'Declaration
 
Public Operator -( _
   ByVal point As LogicalPoint, _
   ByVal size As LogicalSize _
) As LogicalPoint

'Usage

public LogicalPoint operator -( 
   LogicalPoint point,
   LogicalSize size
)

This operator type is not supported by WinRT JavaScript

public:
LogicalPoint operator -( 
   LogicalPoint point,
   LogicalSize size
)

Parameters

point: Specifies the LogicalPoint.
size: Specifies the LogicalSize.

Remarks

The unit of measurement of the new LogicalPoint is the same as the unit of measurement of the passed LogicalPoint. The X-Coordinate of the new LogicalPoint equals the subtraction of the Width property of the passed LogicalSize from the X-Coordinate of the passed LogicalPoint, i.e. new X = X - Width. The Y-Coordinate of the new LogicalPoint equals the subtraction of the Height property of the passed LogicalSize from the Y-Coordinate of the passed LogicalPoint, i.e. new Y = Y - Height.

Example

Visual Basic
C#
WinRT C#
WinRT JavaScript
Silverlight C#
Silverlight VB

'''This example subtracts two point structures.
Public Sub LogicalPoint_OperatorMinus()
   Dim sz As LogicalSize = New LogicalSize(2, 3, LogicalUnit.Centimeter)
   Dim pt As LogicalPoint = New LogicalPoint(1.5F, 2f, LogicalUnit.Inch)
   Dim s As String = String.Format("pt - sz = {0}", pt - sz)
   MessageBox.Show(s)
End Sub
