My Leopard-only application needs to be able to import any image
supported by CGImageSource, so I create an NSOpenPanel and pass the
array obtained from CGImageSourceCopyTypeIdentifiers() to
runModalForTypes. This makes the "Media > Photos" sidebar to show up
automatically in the Open panel, which is great.
However, seemingly random pictures in the iPhoto section of this Media
Browser are greyed out. I tracked it down, and the problem is that
when iPhoto creates an alias to an original file, this is not
automatically resolved. (My OpenPanel does leave -resolvesAliases set
to YES.) So the type of these random pictures is com.apple.alias-file
instead of public.jpeg or any other image format, and the media panel
doesn't let me choose these original files even though their aliases
would resolve to supported types.
Shouldn't these aliases be resolved before type checking, so that the
CGImageSource type identifiers can be used in an open panel without
needing custom delegate filtering?
thanks,
