# CIRAWFilter

A filter subclass that produces an image by manipulating RAW image sensor data from a digital camera or scanner.

## Declaration

```swift
class CIRAWFilter
```

## Overview

Overview Use this class to generate a CIImage object based on the configuration parameters you provide. You can use this object in conjunction with other Core Image classes—such as CIFilter and CIContext—to take advantage of the built-in Core Image filters when processing images or writing custom filters. You can also query this object to find out about the supported camera models, decoders, and filters.
