Let the user draw rotated skewed polygons in C#
The example Let the user draw rotated polygons with right angles in C# draws polygons with edges that are parallel or perpendicular to a baseline. This example is very similar except its polygons have edges that are parallel to one … Continue reading
Let the user draw rotated polygons with right angles in C#
This example lets the user draw rotated polygons where all edges are either parallel or perpendicular to a defined baseline direction. As a result, all of the polygon’s angles are right angles. (And yes, I know that the polygons aren’t … Continue reading
