It's not stated in documentation for CGImageSourceCopyPropertiesAtIndex function. But am i right that i should call CFRelease on retured CFDictionaryRef ?

Quick sample:

NSDictionary* metadata = (NSDictionary   *)CGImageSourceCopyPropertiesAtIndex(source,0,NULL);
......................
//Should i call CFRelease(metadata); ??

Thanks.
