Initializes a newly allocated bitmap image representation from the specified data.

## Declaration

```swift
init?(data: Data)
```

## Parameters

## Return Value

Return Value Returns an initialized NSBitmapImageRep if the initialization was successful or nil if it was unable to interpret the contents of bitmapData.
