Box Objects

A Box represents an axis-aligned bounding box.

Properties

The box as a Polygon.

in checks if a Box contains the given Coordinate (or another Box).

>>> Coordinate(50,100) in Box(10,20,300,200)
True
>>> Box(-20,30,100,50) in Box(10,20,300,200)
False

+ expands a Box so it contains a given Coordinate (or another Box).

>>> b = Box(10,20,300,200)
>>> b + Coordinate(400,300)
Box(10, 20, 400, 300)

| does the same:

>>> Box(10,20,300,200) | Box(50,70,400,500)
Box(10,20,400,500)

& returns the intersection of two Box objects (or an empty box if they don’t intersect).

>>> a = Box(10,20,300,200)
>>> b = Box(50,70,400,500)
>>> a & b
Box(50, 70, 300, 200)

Since an empty Box is falsy, you can use & to check if two boxes intersect:

if a & b:
    print("The bounding boxes intersect.")

Expands this box in all directions by the given distance. Negative values shrink it (which may result in an empty box).

Same as buffer(), but returns a copy, leaving this box unmodified.
