# rawPhotoPixelFormatType

An identifier for the Bayer RAW pixel format to deliver captured RAW photos in.

## Declaration

```swift
var rawPhotoPixelFormatType: OSType { get }
```

## Discussion

Discussion This property is read-only—you specify a RAW pixel format when creating a settings object with the init(rawPixelFormatType:), init(rawPixelFormatType:processedFormat:) initializer. When capturing RAW images, the following requirements apply: The isAutoStillImageStabilizationEnabled setting must be false. Your delegate object must implement the photoOutput(_:didFinishProcessingRawPhoto:previewPhoto:resolvedSettings:bracketSettings:error:) method. The isHighResolutionPhotoEnabled setting may be true or false, but that setting applies only to the separate processed image. (You request separate processed images with the init(rawPixelFormatType:processedFormat:) initializer. This restriction does not apply when you request RAW-only capture with the init(rawPixelFormatType:) initializer). The capture output validates these requirements when you call the capturePhoto(with:delegate:) method. If your settings and delegate do not meet these requirements, that method raises an exception.
