Size::operator- method (gdiplustypes.h)

Article
02/22/2024

The Size::operator- method subtracts the Width and Height data members of two Size objects.

Syntax

Size operator-(
  [in, ref] const Size & sz
);

Parameters

[in, ref] sz

Type: const Size

Reference to a Size object whose Width and Height data members are subtracted from the Width and Height data members of this Size object.

Return value

Type: Size

This method returns the difference of this Size object and another Size object.

Remarks

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

Examples

VOID Example_OperatorMinus(HWND hWnd)
{
   Graphics graphics(hdc);
   Pen pen(Color(255, 0, 0, 0));

   Size size1(200, 100);
   Size size2(50, 40);
   
   Size size3 = size1 - size2;

   graphics.DrawRectangle(&pen, 50, 50, size1.Width, size1.Height);
   graphics.DrawRectangle(&pen, 50, 50, size2.Width, size2.Height);
   graphics.DrawRectangle(&pen, 50, 50, size3.Width, size3.Height);
}
