Rectangle rectangle1 = Rectangle(20,20,50,100);
// Draw its outline.
e->Graphics->DrawRectangle( Pens::SlateBlue, rectangle1 );
// Change the page scale.
e->Graphics->PageUnit = GraphicsUnit::Point;
// Draw the rectangle again.
e->Graphics->DrawRectangle( Pens::Tomato, rectangle1 );
}
private void ChangePageUnit(PaintEventArgs e)
{
// Create a rectangle.
Rectangle rectangle1 = new Rectangle(20, 20, 50, 100);
// Draw its outline.
e.Graphics.DrawRectangle(Pens.SlateBlue, rectangle1);
// Change the page scale.
e.Graphics.PageUnit = GraphicsUnit.Point;
// Draw the rectangle again.
e.Graphics.DrawRectangle(Pens.Tomato, rectangle1);
}
