# canInit(with:)

Returns a Boolean value that indicates whether the image representation can initialize itself from the specified data.

## Declaration

```swift
class func canInit(with data: Data) -> Bool
```

## Parameters

- `data`: The image data.

## Return Value

Return Value true if the receiver understands the format of the specified data and can use it to initialize itself; otherwise, false.

## Discussion

Discussion This method should be overridden by subclasses. Note that this method does not need to do a comprehensive check of the image data; it should return false only if it knows it cannot initialize itself from the data.
