# PKStrokePathReference

A class that captures the components of a stroke and provides methods to find and interpolate points along the stroke’s path.

## Declaration

```swift
class PKStrokePathReference
```

## Topics

### Creating a new stroke path

- [init(controlPoints:creationDate:)](pencilkit/pkstrokepathreference/init(controlpoints:creationdate:).md)

### Getting the stroke path properties

- [count](pencilkit/pkstrokepathreference/count.md)
- [creationDate](pencilkit/pkstrokepathreference/creationdate.md)

### Accessing and interpolating points

- [enumerateInterpolatedPoints(in:strideByParametricStep:using:)](pencilkit/pkstrokepathreference/enumerateinterpolatedpoints(in:stridebyparametricstep:using:).md)
- [enumerateInterpolatedPoints(in:strideByTime:using:)](pencilkit/pkstrokepathreference/enumerateinterpolatedpoints(in:stridebytime:using:).md)
- [interpolatedLocation(at:)](pencilkit/pkstrokepathreference/interpolatedlocation(at:).md)
- [interpolatedPoint(at:)](pencilkit/pkstrokepathreference/interpolatedpoint(at:).md)
- [parametricValue(_:offsetByDistance:)](pencilkit/pkstrokepathreference/parametricvalue(_:offsetbydistance:).md)
- [parametricValue(_:offsetByTime:)](pencilkit/pkstrokepathreference/parametricvalue(_:offsetbytime:).md)
- [point(at:)](pencilkit/pkstrokepathreference/point(at:).md)
- [subscript(_:)](pencilkit/pkstrokepathreference/subscript(_:).md)
