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

orientation

Polar angle of pattern, i.e., the orientation in the Cartesian coordinate system, with zero at 3 o'clock and increasing counterclockwise.

Value:

Number(precedence=-1)
