How to connect two polygons with a perpendicular line? The line doesn't have to be at the actual points, just somewhere on the outer shape connected to the inner shape. I used roipoly to create the polygons.

Here is a picture of the two polygons. I am trying to create perpendicular lines connecting the blue shape to the red shape.

A projection is always "perpendicular". I put in the quote because:
- if the closest point falls on a vertex, then you have two edges that are not in general parallel, so in the strict sense it doesn't mean anything meaningful, since the tangent is not defined at the vertexes. Since you works with a polygonal, therefore a piecewise linear shape.
- If the closest point is in the middle of the edge, then yes.
