Drawing a rectangle with 2 radiused corners

[bartjeman]

I've used "com.sun.star.drawing.RectangleShape" and "com.sun.star.drawing.PolyPolygonShape" to good effect.
But I have a new project that requires a rectangle with 2 sharp corners, and 2 radiused corners.

When I look at the API I can see
RecatangleShape -> LineProperties -> PolyPolygonBezierCoords LineStart and PolyPolygonBezierCoords LineEnd
But I am no closer to a solution

Can someone get me started?

Draw the desired shape.
Inspect object with MRI or XRay.

I will give that a try, sure to be back here with questions
