Symbolizer for linear geometries that consists of a color and a width.

>>> Stroke('#00ff00', 4)
Stroke(color=(0,255,0),width=4)

The color argument may also be specified as a well known name or as an rgb tuple.

>>> stroke = Stroke('green', 4)

The cap argument specifies how lines should be capped. Supported values include “butt”, “round”, and “square”. The ``join``argument specifies how two lines should be joined. Supported values include “miter”, “round”, and “bevel”.

hatch(name, stroke=None, size=None)

Composes the stroke with a hatched pattern.
