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

C#
Visual Basic
Objective-C
Java
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
)

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

This example subtracts the point structure by size structure (offset).
