Translates a PointF by the negative of a given Size.

C# 
public static System.Drawing.PointF operator -(System.Drawing.PointF pt, System.Drawing.Size sz);

Parameters

pt
PointF

The PointF to translate.

sz
Size

The Size that specifies the numbers to subtract from the coordinates of pt.

Returns

PointF

The translated PointF.

Subtraction(PointF, SizeF)

Source:
PointF.cs
Source:
PointF.cs
Source:
PointF.cs

Translates a PointF by the negative of a specified SizeF.

C# 
public static System.Drawing.PointF operator -(System.Drawing.PointF pt, System.Drawing.SizeF sz);

Parameters

pt
PointF

The PointF to translate.

sz
SizeF

The SizeF that specifies the numbers to subtract from the coordinates of pt.

Returns

PointF

The translated 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.

C# 
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);
}

Remarks

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.

The equivalent method for this operator is PointF.Subtract(PointF, SizeF)
