sknano.core.geometric_regions.Square

class sknano.core.geometric_regions.Square(center=None, a=1)

Geometric2DRegion for a square.

New in version 0.3.0.

Represents the axis-aligned bounded region with center \((c_x, c_y)\) and side length \(a\).

Parameters:

center : array_like, optional

The center point coordinate \((c_x, c_y)\) of the axis-aligned square.

a : float, optional

The side length \(a\) of the axis-aligned square.

Notes

Square represents the region \(\left\{\{c_i\pm\frac{a}{2}\}|a>0\forall i\in\{x,y\}\right\}\).

Calling Square with no parameters is equivalent to Square(center=[0, 0], a=1).

Attributes

a	Side length \(a\) of the axis-aligned square.
area	Square area, \(A=a^2\).
center	Center point \((c_x, c_y)\) of axis-aligned square.
centroid	Alias for center.
fmtstr	Format string.
measure	Alias for area, which is the measure of a 2D geometric region.

Methods

center_centroid()	Center centroid on origin.
contains(point)	Test region membership of point in Square.
rotate([angle, axis, anchor_point, ...])	Rotate GeometricRegion points and vectors.
todict()	Returns a dict of the Square constructor parameters.
translate(t[, fix_anchor_points])	Translate GeometricRegion points and vectors by Vector t.
