Method Details

[hide private]

function(self, params)

source code

Function to draw a pattern that will then be scaled and rotated.

Instead of implementing __call__ directly, PatternGenerator subclasses will typically implement this helper function used by __call__, because that way they can let __call__ handle the scaling and rotation for them. Alternatively, __call__ itself can be reimplemented entirely by a subclass (e.g. if it does not need to do any scaling or rotation), in which case this function will be ignored.

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

Class Variable Details

frequency

Frequency of the sine grating component.

Value:

param.Number(default= 2.4, bounds= (0.0, None), softbounds= (0.0, 10.0), precedenc
e= 0.50, doc= "Frequency of the sine grating component.")

phase

Phase of the sine grating component.

Value:

param.Number(default= 0.0, bounds= (0.0, None), softbounds= (0.0, 2* pi), preceden
ce= 0.51, doc= "Phase of the sine grating component.")

aspect_ratio

Ratio of pattern width to height. The width of the Gaussian component is size*aspect_ratio (see Gaussian).

Value:

param.Number(default= 1.0, bounds= (0.0, None), softbounds= (0.0, 2.0), precedence
= 0.31, doc= """
        Ratio of pattern width to height.
        The width of the Gaussian component is size*aspect_ratio (see Gaussian).

size

Determines the height of the Gaussian component (see Gaussian).

Value:

param.Number(default= 0.25, doc= """
        Determines the height of the Gaussian component (see Gaussian).""")
