Hi everyone,
I'm trying to set the artwork of some iTunes tracks using Cocoa &
Scripting Bridge. The artwork is being generated using Cocoa, and I
planned to use the SB to set the NSImage to the iTunesTracks.
However after reading this thead, it seems that it isn't really
feasable (if someone has managed to do it correctly - then that would
be great!) So, it looks like I've got to use AppleScript... which I've
never really had much luck with... So, I'm hoping someone can help me
go from having an NSImage in an Objective-C class to calling this
set data of front artwork of someTrackReference to somePICTData
in AppleScript? I'm guessing I need to write some function in
Applescript, and pass in references to the track and the image data.
Ideally I'd like to not have to write the images to disk and then pass
in a filepath. If anyone can tell me how to do this that would be great!
Cheers
Dan

I haven't delved deeply into Scripting Bridge, but based on
something similar that occurs when Applescripting iTunes, I suspect
the problem is in the line:
[[track artworks] insertObject: artwork atIndex: 0];
A track's "artworks" does not exist for tracks which do not already
contain artwork. Further, if you try to access it (or "kind of front
artwork"), certain versions of iTunes will return the classic "Apple
event not handled" error -1708. Other versions will return 0, as one
might expect.
In any case, your solution in SB likely involves avoiding "artworks"
altogether. Basically you want to replicate the Applescript command
set data of front artwork of someTrackReference to somePICTData
Observe that "artworks" is not involved at all. It will only exist
for the track after some artwork data has been added.
(PS. I think it's preferable to include small code snippets in list
postings rather as links to some external "snippets" web page. For
one thing, that page may not exist years from now. For another,
people who could possibly help with your issue may not bother to
click your link. I almost didn't.)
