title: Path.clean()
|
|
---
|
|
|
|
The `Path.clean()` method removes spurious drawing operations from a path.
|
|
|
|
A _spurious_ drawing operation is one that has no effect, but can still cause
|
|
problems if left in place. For example, a line from a given point to the same
|
|
given point will not cause any problems as such, but can trip up things like
|
|
path offset and other methods. For this reason, such drawing operations can be
|
|
cleaned up with the `Path.clean()` method.
|
|
|
|
As this method is called under the hood to guard against various scenarios
|
|
where spurious segments could cause an issue, you should have no need to call
|
|
this method yourself explicitly, but it's there if you need it. path that you
|
|
pass it.

## Signature

|
```js
|
|
Path path.clean()
|
|
```
|
|
|
|
## Example
