Method Details [hide private]

__call__(self, **params_to_override)
(Call operator)

source code 

Call the subclasses 'function' method on a rotated and scaled coordinate system.

Creates and fills an array with the requested pattern. If called without any params, uses the values for the Parameters as currently set on the object. Otherwise, any params specified override those currently set on the object.

Overrides: base.patterngenerator.PatternGenerator.__call__
(inherited documentation)

Class Variable Details [hide private]

__abstract

bool(x) -> bool

Returns True when the argument x is true, False otherwise. The builtins True and False are the only two instances of the class bool. The class bool is a subclass of the class int, and cannot be subclassed.

Value:
True

random_generator

numpy's RandomState provides methods for generating random numbers (see RandomState's help for more information).

Note that all instances will share this RandomState object, and hence its state. To create a RandomGenerator that has its own state, set this parameter to a new RandomState instance.

Value:
param.Parameter(default= numpy.random.RandomState(seed= (500, 500)), precedence=-1\
