Get span of RectangleShape

[Squareys]

Hi @tpietzsch !

I am currently working on some neighborhood operations code, especially for imagej-ops. I need to access the span of an existing RectangleShape, but neither Shape nor RectangleShape have a simple way to access it.

I guess you can probably get the span over the bounding box of the neighborhood, but that does not seem very nice.

Ideas:
Common for all shapes is a bounding box. What would you thing of a method to retrieve this bounding box/interval for example?
Another idea could be to have every Shape subclass provide getters for their parameters. Not all shapes have a span, obviously.

If you tell me, how you would want a solution to this to look, I could implement it.

Greeting,

@Squareys I think both would be good: for every Shape to be able to provide a bounding box interval and adding subclass-specific methods to e.g. RectangleShape.

Regarding bounding box interval: Neighborhood already has a public Interval getStructuringElementBoundingBox() method. Because Shape does not have fixed dimensionality it would have to be public Interval getStructuringElementBoundingBox(int numDimensions) for Shape.

It would be cool if you could work on this!

Let's leave this issue open until the generic bounding box interval is implemented

@tpietzsch I have implemented the bounding box for Shapes, see #27.

From your last comment it is not entirely clear, if you were aiming for something even more general like a BoundingBox interface?
