Examples
The following code example demonstrates how to use the MakeInfinite method. This example is designed to be used with Windows Forms. Create a form and paste the following code into it. Call the FillEmptyRegion
method in the form's Paint event-handling method, passing e
as PaintEventArgs.
private:
void FillInfiniteRegion( PaintEventArgs^ e )
{
// Create a region from a rectangle.
Rectangle originalRectangle = Rectangle(40,40,40,50);
System::Drawing::Region^ smallRegion = gcnew System::Drawing::Region( originalRectangle );
// Call MakeInfinite.
smallRegion->MakeInfinite();
// Fill the region in red and draw the original rectangle
// in black. Note that the entire form is filled in.
e->Graphics->FillRegion( Brushes::Red, smallRegion );
e->Graphics->DrawRectangle( Pens::Black, originalRectangle );
}
private void FillInfiniteRegion(PaintEventArgs e)
{
// Create a region from a rectangle.
Rectangle originalRectangle = new Rectangle(40, 40, 40, 50);
Region smallRegion = new Region(originalRectangle);
// Call MakeInfinite.
smallRegion.MakeInfinite();
// Fill the region in red and draw the original rectangle
// in black. Note that the entire form is filled in.
e.Graphics.FillRegion(Brushes.Red, smallRegion);
e.Graphics.DrawRectangle(Pens.Black, originalRectangle);
}
Private Sub FillInfiniteRegion(ByVal e As PaintEventArgs)
' Create a region from a rectangle.
Dim originalRectangle As New Rectangle(40, 40, 40, 50)
Dim smallRegion As New Region(originalRectangle)
' Call MakeInfinite.
smallRegion.MakeInfinite()
' Fill the region in red and draw the original rectangle
' in black. Note that the entire form is filled in.
e.Graphics.FillRegion(Brushes.Red, smallRegion)
e.Graphics.DrawRectangle(Pens.Black, originalRectangle)
End Sub
