libpysal.cg.LineSegment¶

class libpysal.cg.LineSegment(start_pt, end_pt)[source]¶

Geometric representation of line segment objects.

Parameters:	start_pt : Point Point where segment begins end_pt : Point Point where segment ends
Attributes:	p1 : Point HELPER METHOD. p2 : Point HELPER METHOD. bounding_box : tuple Returns the minimum bounding box of a LineSegment object. len : float Returns the length of a LineSegment object. line : Line Returns a Line object of the line which the segment lies on.

Methods

get_swap()	Returns a LineSegment object which has its endpoints swapped.
intersect(other)	Test whether segment intersects with other segment
is_ccw(pt)	Returns whether a point is counterclockwise of the segment.
is_cw(pt)	Returns whether a point is clockwise of the segment.
sw_ccw(pt)	Sedgewick test for pt being ccw of segment

__init__(start_pt, end_pt)[source]¶

Creates a LineSegment object.

__init__(Point, Point) -> LineSegment

Test tag: <tc>#is#LineSegment.__init__</tc> Test tag: <tc>#tests#LineSegment.__init__</tc>

Examples

>>> ls = LineSegment(Point((1, 2)), Point((5, 6)))
