# kCVImageBufferDisplayMaskRectangle_RightEdgePointsKey

Specifies inset points on the right vertical edge of the rectangle.

```
let kCVImageBufferDisplayMaskRectangle_RightEdgePointsKey: CFString
```

## Discussion

The points are <doc://com.apple.documentation/documentation/CoreFoundation/CFArray> of unsigned 16-bit integer <doc://com.apple.documentation/documentation/CoreFoundation/CFNumber> pairs alternating between inset X and inset Y.
Inset X is an unsigned offset from the right edge (`0`) towards the left edge (width).
Inset Y is an unsigned offset from the top edge (`0`) towards the bottom edge (height).
