Applies to: desktop apps only

The PointF::operator- method subtracts the X and Y data members of two PointF objects.

Syntax

PointF operator-(
  [in, ref]  const PointF &point
);

Parameters

point [in, ref]
Type: const PointF

Reference to a PointF object whose X and Y data members are subtracted from the X and Y data members of this PointF object.

Return value

Type:

Type: PointF****

This method returns a PointF object that is the difference of two PointF objects.

Remarks

This method overloads the subtraction operator for PointF objects. If A, B, and C are PointF objects, the statement C = A - B is equivalent to C = A.operator-(B).

Examples

The following example creates two PointF objects, then subtracts the second PointF object from the first PointF object and stores the result in a third PointF object.

PointF point1(40.0f, 10.0f);
PointF point2(-20.0f, -30.0f);

// Point3 now contains the coordinates (60.0f, 40.0f).
PointF point3 = point1 - point2;
