A line join is the common area that is formed by two lines whose ends meet or overlap. There are three line join styles: miter, bevel, and round. When you specify a line join style for a xtd::drawing::pen object, that join style will be applied to all the connected lines in any xtd::drawing::drawing_2d::graphics_path object drawn using that pen. The following illustration shows the results of the beveled line join example.
