PointF::operator- method (gdiplustypes.h)
The PointF::operator- method subtracts the X and Y data members of two PointF objects.
Syntax
PointF operator-(
[in, ref] const PointF & point
);
Parameters
[in, ref] point
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: 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;
