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?
Yes, it should -- can you please log a bug? If possible include
steps for how to create the aliases.
Glad to hear it, the bug is rdar://problem/6410673 and should already
have some info on how to reproduce. Please let me know if there's
anything more you need.
In the meantime, I've worked around this by having the NSOpenPanel
accept kUTTypeData to get all files plus kUTTypeJPEG to trigger the
photo media browser, then in my own -panel:shouldShowFilename checking
the target types plus resolving and rechecking any kUTTypeAliasFile
types that slip through at present.
