Syntax

C++

Copy

public static PointF operator -(
	PointF pt,
	SizeF sz
)

Parameters

pt: Type: System.Drawing.PointF
The PointF to translate.

sz: Type: System.Drawing.SizeF
The SizeF that specifies the numbers to subtract from the coordinates of pt.

Return Value

The Subtraction operator subtracts the Width of the specified size from the x-coordinate of the PointF and the Height from the y-coordinate of the PointF.

Examples

The following code example demonstrates how to use the Subtraction operator. To run this example, paste the following code into a Windows Form. Handle the form's Paint event and call opSubtractionExample, passing e as PaintEventArgs.

Copy


private void OpSubtractionExample(PaintEventArgs e)
{
    PointF point1 = new PointF(120.5F, 120F);
    SizeF size1 = new SizeF(20.5F, 20.5F);
    PointF point2 = point1 - size1;
    e.Graphics.DrawLine(Pens.Blue, point1, point2);
}
