Discussion

If sent to the NSImageRep class object, this method returns an array of objects (all newly allocated instances of a subclass of NSImageRep) that have been initialized with the contents of the specified URL. If sent to a subclass of NSImageRep that recognizes the data at the specified URL, it returns an array of objects (all instances of that subclass) that have been initialized with the contents of that 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 data in the specified URL.

  • The message is sent to a subclass of NSImageRep and that subclass cannot handle data 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 specified URL and passing it to the imageRepsWithData: method.
