Class API¶

class PointsObjectMixin¶

A mixin class that provides some methods suitable for use with objects that have a set of (x, y) coordinate pairs.

Methods¶

CalcBoundingBox(self)¶: Calculate the bounding box.

Move(self, Delta)¶

Moves the object by delta, where delta is a (dx, dy) pair.

Parameters:: Delta – is a (dx, dy) pair ideally a NumPy array of shape (2, )

SetPoints(self, Points, copy=True)¶

Sets the coordinates of the points of the object to Points (NX2 array).

Parameters:

Points –
takes a 2-tuple, or a (2,) NumPy array of point coordinates
copy (boolean) – By default, a copy is made, if copy is set to False, a reference is used, if Points is a NumPy array of Floats. This allows you to change some or all of the points without making any copies.

For example:

Points = Object.Points
# shifts the points 5 in the x dir, and 10 in the y dir.
Points += (5, 10)
# Sets the points to the same array as it was
Object.SetPoints(Points, False)
