# PKStrokePointReference

A class that represents the properties of a specific point along a stroke’s path.

## Declaration

```swift
class PKStrokePointReference
```

## Topics

### Creating a stroke point object

- [init(location:timeOffset:size:opacity:force:azimuth:altitude:)](pencilkit/pkstrokepointreference/init(location:timeoffset:size:opacity:force:azimuth:altitude:).md)
- [init(location:timeOffset:size:opacity:force:azimuth:altitude:secondaryScale:)](pencilkit/pkstrokepointreference/init(location:timeoffset:size:opacity:force:azimuth:altitude:secondaryscale:).md)

### Getting the point’s location

- [location](pencilkit/pkstrokepointreference/location.md)
- [timeOffset](pencilkit/pkstrokepointreference/timeoffset.md)

### Getting the point’s touch data

- [altitude](pencilkit/pkstrokepointreference/altitude.md)
- [azimuth](pencilkit/pkstrokepointreference/azimuth.md)
- [force](pencilkit/pkstrokepointreference/force.md)

### Getting the point’s drawing data

- [size](pencilkit/pkstrokepointreference/size.md)
- [opacity](pencilkit/pkstrokepointreference/opacity.md)
- [secondaryScale](pencilkit/pkstrokepointreference/secondaryscale.md)

### Initializers

- [init(location:timeOffset:size:opacity:force:azimuth:altitude:secondaryScale:threshold:)](pencilkit/pkstrokepointreference/init(location:timeoffset:size:opacity:force:azimuth:altitude:secondaryscale:threshold:).md)
- [init(location:timeOffset:size:opacity:force:azimuth:altitude:secondaryScale:threshold:lateralJitter:)](pencilkit/pkstrokepointreference/init(location:timeoffset:size:opacity:force:azimuth:altitude:secondaryscale:threshold:lateraljitter:).md)

### Instance Properties

- [lateralJitter](pencilkit/pkstrokepointreference/lateraljitter.md)
- [threshold](pencilkit/pkstrokepointreference/threshold.md)
