# roiTileCount

This property tells a tiled-input processor how many input tiles will be processed.

## Declaration

```swift
var roiTileCount: Int { get }
```

## Discussion

Discussion This property is only relevant if your processor implements /CIImageProcessorKernel/roiTileArrayForInput:arguments:outputRect: This can be useful if the processor needs to do work CIImageProcessorOutput after the last tile is processed.
