A base class for path effects.
|

|
|
|
|||
|
|
Subclasses should override the ``draw_path`` method to add effect
|

|
|
functionality.

|
|||
|
|
A line-based PathEffect which draws a path with a ticked style.
|
|||
|
|
|
|||
|
|
This line style is frequently used to represent constraints in
|
|||
|
|
optimization. The ticks may be used to indicate that one side
|
|||
|
|
of the line is invalid or to represent a closed boundary of a
|
|||
|
|
domain (i.e. a wall or the edge of a pipe).
|
|||
|
|
|
|||
|
|
The spacing, length, and angle of ticks can be controlled.
|
|||
|
|
|
|||
|
|
This line style is sometimes referred to as a hatched line.
|
|||
|
|
|
|||
|
|
