# init(contentsOf:) Creates and returns an image representation object using the data at the specified URL. ``` init?(contentsOf url: URL) ``` ## Parameters `url` The URL pointing to the image data. ## Return Value An initialized instance of an `NSImageRep` subclass, or `nil` if the image data could not be read. ## Discussion If sent to the `NSImageRep` class object, this method returns a newly allocated instance of a subclass of `NSImageRep` initialized with the contents of the specified URL. If sent to a subclass of `NSImageRep` that recognizes the data contained in the URL, it returns an instance of that subclass initialized with the data in the URL. This method returns `nil` in any of the following cases: - The message is sent to the `NSImageRep` class object and there are no subclasses in the `NSImageRep` class registry that handle the data contained in the specified URL. - The message is sent to a subclass of `NSImageRep` and that subclass cannot handle the data contained in the specified URL. - The `NSImageRep` subclass is unable to initialize itself with the contents of the specified URL. The `NSImageRep` subclass is initialized by creating an `NSData` object based on the contents of the file, then passing it to the `imageRepWithData:` method. --- Copyright © 2026 Apple Inc.
