wx.lib.floatcanvas.Utilities.BBox.BBox¶

A Bounding Box object:

Takes Data as an array. Data is any python sequence that can be turned into a 2x2 numpy array of floats:

[
[MinX, MinY ],
[MaxX, MaxY ]
]


It is a subclass of numpy.ndarray, so for the most part it can be used as an array, and arrays that fit the above description can be used in its place.

Usually created by the factory functions:

asBBox

and

fromPoints

Class API¶

class BBox(N.ndarray)

A Bounding Box object:

Takes Data as an array. Data is any python sequence that can be turned into a 2x2 numpy array of floats:

[
[MinX, MinY ],
[MaxX, MaxY ]
]


It is a subclass of numpy.ndarray, so for the most part it can be used as an array, and arrays that fit the above description can be used in its place.

Usually created by the factory functions:

asBBox

and

fromPoints

Methods¶

Inside(self, BB)

Inside(BB):

Tests if the given Bounding Box is entirely inside this one.

Returns True if it is entirely inside, or touching the border.

Returns False otherwise

IsNull(self)

Merge(self, BB)

Joins this bounding box with the one passed in, maybe making this one bigger

Overlaps(self, BB)

Overlap(BB):

Tests if the given Bounding Box overlaps with this one. Returns True is the Bounding boxes overlap, False otherwise If they are just touching, returns True

PointInside(self, Point)

Inside(BB):

Tests if the given Point is entirely inside this one.

Returns True if it is entirely inside, or touching the border.

Returns False otherwise

Point is any length-2 sequence (tuple, list, array) or two numbers
