PointF.Subtraction Operator

Definition

Namespace:

System.Drawing

Assembly:

System.Drawing.Primitives.dll

Translates a PointF by the negative of a specified size.

Overloads

Subtraction(PointF, Size)	Translates a PointF by the negative of a given Size.
Subtraction(PointF, SizeF)	Translates a PointF by the negative of a specified SizeF.

Subtraction(PointF, Size)

Source:

PointF.cs

Translates a PointF by the negative of a given Size.

public:
 static System::Drawing::PointF operator -(System::Drawing::PointF pt, System::Drawing::Size sz);

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

static member ( - ) : System.Drawing.PointF * System.Drawing.Size -> System.Drawing.PointF

Public Shared Operator - (pt As PointF, sz As Size) As PointF

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

Translates a PointF by the negative of a specified SizeF.

public:
 static System::Drawing::PointF operator -(System::Drawing::PointF pt, System::Drawing::SizeF sz);

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

static member ( - ) : System.Drawing.PointF * System.Drawing.SizeF -> System.Drawing.PointF

Public Shared Operator - (pt As PointF, sz As SizeF) As PointF

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.

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);
}

Private Sub OpSubtractionExample(ByVal e As PaintEventArgs) 
    Dim point1 As New PointF(120.5F, 120F)
    Dim size1 As New SizeF(120.5F, 30.5F)
    Dim point2 As PointF = point1 - size1
    e.Graphics.DrawLine(Pens.Blue, point1, point2)

End Sub

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)
