# horizontalSampleStorage

A pointer to the storage for the layer map’s horizontal rasterization rates.

```
@property (nonatomic, readonly) float * horizontalSampleStorage;
```

## Discussion

Points to the first element in the array of horizontal rasterization rates. The number of elements is equal to the [`width`](/documentation/Metal/MTLSize/width) value of [`sampleCount`](/documentation/Metal/MTLRasterizationRateLayerDescriptor/sampleCount).
