There are a couple ways you can go about this. The most direct
choice is to use the CGImageDestination component here:
http://tuvix.apple.com/documentation/GraphicsImaging/Reference/
CGImageDestination/Reference/reference.html
Then use these keys in the properties dictionary:
http://tuvix.apple.com/documentation/GraphicsImaging/Reference/
CGImageSource/Reference/reference.html#//apple_ref/doc/uid/TP40001399-
CH3g-DontLinkElementID_18
In Cocoa you can use this method in NSBitmapImageRep using the same
constants as the above link:
http://tuvix.apple.com/documentation/Cocoa/Reference/ApplicationKit/
Classes/NSBitmapImageRep_Class/Reference/Reference.html#//apple_ref/

Hello All,
I'm trying to edit GPS Exif tags in jpegs as part of iPhoto plugin
and though I can find a few libraries that will read Exif data but
given Spotlights metadata magic I had hoped that there would be
something in Cocoa to help me. Has anyone here tried this before,
and where did it get you? If there are non-cocoa solutions perhaps
it would be better to reply off list.
cheers,
Craig
