The ImageIO framework has mechanisms for this. It isn't Cocoa, but
it's easy to use from a Cocoa app.
See <http://developer.apple.com/documentation/GraphicsImaging/Reference/CGImageSource/index.html>
and <http://developer.apple.com/documentation/GraphicsImaging/Reference/CGImageDestination/index.html>.
One caveat: I have not found a way to modify metadata in a JPEG file
without recompressing the image data.
