# AVCapturePhotoFileDataRepresentationCustomizer

A protocol that defines the methods to implement to customize the packaging of photo data.

## Declaration

```swift
protocol AVCapturePhotoFileDataRepresentationCustomizer : NSObjectProtocol
```

## Mentioned in

Capturing photos in RAW and Apple ProRAW formats

## Overview

Overview AVCapturePhoto is a wrapper representing a photo in a file container. To flatten the photo to an NSData object to write to file, call fileDataRepresentation(). For more complex flattening operations such as replacing or stripping metadata, call fileDataRepresentation(with:) and provide a delegate for customized replacement or stripping behavior. This delegate’s methods are called synchronously before the flattening process begins.
