# PKStrokeReference

A class that represents the paths, boundaries and other properties of a stroke drawn on a canvas.

## Declaration

```swift
class PKStrokeReference
```

## Topics

### Creating a stroke object

- [init(ink:strokePath:transform:mask:)](pencilkit/pkstrokereference/init(ink:strokepath:transform:mask:).md)
- [init(ink:strokePath:transform:mask:randomSeed:)](pencilkit/pkstrokereference/init(ink:strokepath:transform:mask:randomseed:).md)

### Getting the stroke properties

- [ink](pencilkit/pkstrokereference/ink.md)
- [mask](pencilkit/pkstrokereference/mask.md)
- [maskedPathRanges](pencilkit/pkstrokereference/maskedpathranges.md)
- [path](pencilkit/pkstrokereference/path.md)
- [renderBounds](pencilkit/pkstrokereference/renderbounds.md)
- [transform](pencilkit/pkstrokereference/transform.md)
- [randomSeed](pencilkit/pkstrokereference/randomseed.md)
