Parameters

Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. The code performs the following actions:

• Creates the first rectangle and draws it to the screen in black.

• Creates a second rectangle and draws it to the screen in red.

• Creates a region using the first rectangle.

• Gets the Xor area for myRegion when combined with complementRect.

• Fills the Xor area with blue and draws it to the screen.

Notice that both rectangles are filled with blue, except for the area of overlap.

void XorExample( PaintEventArgs^ e )
{
   // Create the first rectangle and draw it to the screen in black.
   Rectangle regionRect = Rectangle(20,20,100,100);
   e->Graphics->DrawRectangle( Pens::Black, regionRect );

   // create the second rectangle and draw it to the screen in red.
   RectangleF xorRect = RectangleF(90,30,100,100);
   e->Graphics->DrawRectangle( Pens::Red, Rectangle::Round( xorRect ) );

   // Create a region using the first rectangle.
   System::Drawing::Region^ myRegion = gcnew System::Drawing::Region( regionRect );

   // Get the area of overlap for myRegion when combined with
   // complementRect.
   myRegion->Xor( xorRect );

   // Fill the Xor area of myRegion with blue.
   SolidBrush^ myBrush = gcnew SolidBrush( Color::Blue );
   e->Graphics->FillRegion( myBrush, myRegion );
}

public void XorExample(PaintEventArgs e)
{
             
    // Create the first rectangle and draw it to the screen in black.
    Rectangle regionRect = new Rectangle(20, 20, 100, 100);
    e.Graphics.DrawRectangle(Pens.Black, regionRect);
             
    // create the second rectangle and draw it to the screen in red.
    RectangleF xorRect = new RectangleF(90, 30, 100, 100);
    e.Graphics.DrawRectangle(Pens.Red,
        Rectangle.Round(xorRect));
             
    // Create a region using the first rectangle.
    Region myRegion = new Region(regionRect);
             
    // Get the area of overlap for myRegion when combined with
             
    // complementRect.
    myRegion.Xor(xorRect);
             
    // Fill the Xor area of myRegion with blue.
    SolidBrush myBrush = new SolidBrush(Color.Blue);
    e.Graphics.FillRegion(myBrush, myRegion);
}

Public Sub XorExample(ByVal e As PaintEventArgs)

    ' Create the first rectangle and draw it to the screen in black.
    Dim regionRect As New Rectangle(20, 20, 100, 100)
    e.Graphics.DrawRectangle(Pens.Black, regionRect)

    ' create the second rectangle and draw it to the screen in red.
    Dim xorRect As New RectangleF(90, 30, 100, 100)
    e.Graphics.DrawRectangle(Pens.Red, Rectangle.Round(xorRect))

    ' Create a region using the first rectangle.
    Dim myRegion As New [Region](regionRect)

    ' Get the area of overlap for myRegion when combined with
    ' complementRect.
    myRegion.Xor(xorRect)

    ' Fill the intersection area of myRegion with blue.
    Dim myBrush As New SolidBrush(Color.Blue)
    e.Graphics.FillRegion(myBrush, myRegion)
