Hallo,
ja, mit Panther und einer Ordneraktion dürfte sowas eigentlich gehen (was heißt: "...das normale OS X" - 10.2?). Bei mir, 10.3., hätte ich auch ein (ähnliches?) Script gefunden, das bei einem Test gerade eben einen zugewiesenen Ordner überwacht hat und z. B. einem jpg-Bild das Vorschau.app-Icon in eine Miniaturansicht verwandelt hat. Ich weiß aber nicht, inwieweit sich das auf den Dateiheader auswirkt und ob das genau das ist, was du suchst. Wie Vevelt schon sagte: jetzt müsste mal ein AppleScript-Fachmann ran - Andi, bist du da?
Hab die Aktion trotzdem mal angehängt (heißt "Add Icon"):
property done_foldername : "Original Images"
-- the list of file types which will be processed
-- eg: {"PICT", "JPEG", "TIFF", "GIFf"}
property type_list : {"JPEG", "TIFF", "PNGf"}
-- since file types are optional in Mac OS X,
-- check the name extension if there is no file type
-- NOTE: do not use periods (.) with the items in the name extensions list
-- eg: {"txt", "text", "jpg", "jpeg"}, NOT: {".txt", ".text", ".jpg", ".jpeg"}
property extension_list : {"jpg", "jpeg", "tif", "tiff", "png"}
on adding folder items to this_folder after receiving these_items
-- CHECK FOR THE DESTINATION FOLDER WITHIN THE ATTACHED FOLDER
-- IF IT DOESN'T EXIST, THEN CREATE IT
tell application "Finder"
if not (exists folder done_foldername of this_folder) then
make new folder at this_folder with properties {name:done_foldername}
set current view of container window of this_folder to list view
end if
set the target_folder to folder done_foldername of this_folder
end tell
-- PROCESS EACH OF THE ITEMS ADDED TO THE ATTACHED FOLDER
try
repeat with i from 1 to number of items in these_items
set this_item to item i of these_items
set the item_info to the info for this_item
-- CHECK TO SEE IF THE ITEM IS AN IMAGE FILE OF THE ACCEPTED FILE TYPE
if (alias of the item_info is false and the file type of the item_info is in the type_list) or (the name extension of the item_info is in the extension_list) then
tell application "Finder"
-- LOOK FOR EXISTING MATCHING ITEMS IN THE DESTINATION FOLDER
-- IF THERE ARE MATCHES, THEN RENAME THE CONFLICTING FILES INCREMENTALLY
my resolve_conflicts(this_item, target_folder)
-- MOVE THE ITEM TO THE DESTINATION FOLDER
set the target_file to (move this_item to the target_folder with replacing) as alias
end tell
-- PROCESS THE ITEM
process_item(target_file)
end if
end repeat
on error error_message number error_number
if the error_number is not -128 then
tell application "Finder"
activate
display dialog error_message buttons {"Cancel"} default button 1 giving up after 120
end tell
end if
end try
end adding folder items to
on resolve_conflicts(this_item, target_folder)
tell application "Finder"
set the file_name to the name of this_item
if (exists document file file_name of target_folder) then
set file_extension to the name extension of this_item
if the file_extension is "" then
set the trimmed_name to the file_name
else
set the trimmed_name to text 1 thru -((length of file_extension) + 2) of the file_name
end if
set the name_increment to 1
repeat
set the new_name to (the trimmed_name & "." & (name_increment as string) & "." & file_extension) as string
if not (exists document file new_name of the target_folder) then
-- rename to conflicting file
set the name of document file file_name of the target_folder to the new_name
exit repeat
else
set the name_increment to the name_increment + 1
end if
end repeat
end if
end tell
end resolve_conflicts
-- this sub-routine processes files
on process_item(this_item)
-- NOTE that the variable this_item is a file reference in alias format
-- FILE PROCESSING STATEMENTS GOES HERE
try
-- convert alias reference to string
set this_item to this_item as string
with timeout of 900 seconds
tell application "Image Events"
launch -- always use with Folder Actions
set this_image to open file this_item
save this_image with icon
close this_image
end tell
end timeout
on error error_message
tell application "Finder"
