*Instance Property*

Defaults to `GSPenOperationQuadratic | GSPenOperationCubic | GSPenOperationQuartic | GSPenOperationHobby | GSPenOperationRaph`.

## Declaration

```swift
var supportedOperations: GSPenOperation { get set }
```

```objc
@property (nonatomic) GSPenOperation supportedOperations;
```

```python
supportedOperations() -> GSPenOperation
setSupportedOperations_(supportedOperations: GSPenOperation)

## Discussion

Set this value to exclude any of the default options to convert them to one of the supported operations. At a minimum, cubic operations must be supported.
