	SizeF sz
)

Parameters

The PointF to translate.

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

Return Value

Type: System.Drawing.PointF

Examples

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

Copy


private void SubtractExample(PaintEventArgs e)
{
    PointF point1 = new PointF(120.5F, 120F);
    SizeF size1 = new SizeF(120.5F, 30.5F);
    PointF point2 = PointF.Subtract(point1, size1);
    e.Graphics.DrawLine(Pens.Blue, point1, point2);
}
