# quadrilateralPoints

An array of values that represents the points bounding the marked-up text.

```
var quadrilateralPoints: [NSValue]? { get set }
```

## Discussion

The array contains `N * 4` <doc://com.apple.documentation/documentation/Foundation/NSValue> objects that use <doc://com.apple.documentation/documentation/Foundation/NSValue/pointValue> or <doc://com.apple.documentation/documentation/Foundation/NSValue/cgPointValue> to define `N` quadrilaterals in page-space coordinates, where `N` is the number of quad points. The order of the points is a Z pattern as follows:

- Upper-left point
- Upper-right point
- Lower-left point
- Lower-right point

The coordinates of each point are relative to the bound’s origin of the annotation.
