# MERAWProcessingParameter

An object for the RAW processor to describe each processing parameter the processor exposes.

## Declaration

```swift
class MERAWProcessingParameter
```

## Discussion

Discussion This protocol provides an interface for Video Toolbox to query descriptions of the different parameters that can be used to influence RAW processor operation.  A distinct MERAWProcessingParameter is created for each parameter supported by the RAW processor, and the set of supported parameters is returned by the processingParameters interface.
