>>> r = Rectangle(-4, 3, 10, 17) >>> r.left #minx -4.0
>>> r.lower #miny 3.0
>>> r.right #maxx 10.0
>>> r.upper #maxy 17.0
- Attributes
- left
python:float
Minimum x-value of the rectangle.
- lower
python:float
Minimum y-value of the rectangle.
- right
python:float
Maximum x-value of the rectangle.
- upper
python:float
Maximum y-value of the rectangle.
- left

__init__
(left, lower, right, upper)[source]¶ Initialize self. See help(type(self)) for accurate signature.
Methods
__init__
(left, lower, right, upper)Initialize self.
set_centroid
(new_center)Moves the rectangle center to a new specified point.
set_scale
(scale)Rescales the rectangle around its center.
Attributes
Returns the area of the Rectangle.
Returns the height of the Rectangle.
Returns the width of the Rectangle.
-
property
area
¶ Returns the area of the Rectangle.
Examples
>>> r = Rectangle(0, 0, 4, 4) >>> r.area 16.0
-
property
height
¶ Returns the height of the Rectangle.
Examples
>>> r = Rectangle(0, 0, 4, 4) >>> r.height 4.0
-
set_centroid
(new_center)[source]¶ Moves the rectangle center to a new specified point.
- Parameters
- new_center
libpysal.cg.Point
The new location of the centroid of the polygon.
- new_center
Examples
>>> r = Rectangle(0, 0, 4, 4) >>> r.set_centroid(Point((4, 4))) >>> r.left 2.0
>>> r.right 6.0
>>> r.lower 2.0
>>> r.upper 6.0
-
set_scale
(scale)[source]¶ Rescales the rectangle around its center.
- Parameters
- scale
python:int
,python:float
The ratio of the new scale to the old scale (e.g. 1.0 is current size).
- scale
Examples
>>> r = Rectangle(0, 0, 4, 4) >>> r.set_scale(2) >>> r.left -2.0 >>> r.right 6.0 >>> r.lower -2.0 >>> r.upper 6.0
-
property
width
¶ Returns the width of the Rectangle.
Examples
>>> r = Rectangle(0, 0, 4, 4) >>> r.width 4.0
