Point::operator- method (gdiplustypes.h)

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

Syntax

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

Parameters

[in, ref] point

Type: const Point

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

Return value

Type: Point

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

Remarks

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

Examples

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

Point point1(40, 10);
Point point2(-20, -30);

// Point3 now contains the coordinates (60, 40).
Point point3 = point1 - point2;
