Method Details

[hide private]

function(self, p)

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

aspect_ratio

Ratio of width to height; size*aspect_ratio gives the width of the rectangle.

Value:

param.Number(default= 1.0, bounds= (0.0, None), softbounds= (0.0, 6.0), precedence
= 0.31, doc= "Ratio of width to height; size*aspect_ratio gives the width of the r
ectangle.")

size

Height of the rectangle.

Value:

param.Number(default= 0.5, doc= "Height of the rectangle.")

smoothing

Width of the Gaussian fall-off outside the rectangle.

Value:

param.Number(default= 0.05, bounds= (0.0, None), softbounds= (0.0, 0.5), precedenc
e= 0.61, doc= "Width of the Gaussian fall-off outside the rectangle.")
