Adobe illustrator CS scriptsing problem.

Question

So i dived into AppleScripting because I have a few hundred stills I ran a Live Trace Batch on. But since Bridge does not allow you to change the Art Board properties before the batch. I need to program a script that can go in and change the Art Board properties. I was hoping to use Automator with Applescript to Batch resize all my stills. So far this is what I have written for the Applescript.
tell application "Adobe Illustrator"
set properties to {width:640, height:480}
end tell
end
I thought this would be straight up easy but i got an error.
set properties to {width:640, height:480}
"Adobe Illustrator CS2 got an error: Can't set properties to {width:640, height:480}."
So it seems I can't set the properties on the art board. Any suggestions or clues or anything would be extremely helpful.
I would also like to add that I wrote a script to make a new document.
tell application "Adobe Illustrator"
if (document 1 exists) then
make document with properties {width:1920, height:1080}
end if
end tell
Which works fine. What I don't understand is why it wont change the Artboard properties of an existing document that I have opened with my first script.

Answer 1

Document page size and colour mode are 2 features that I have submitted a request to be changed from read only properties with adobe hopefully it may make a future release of this application. For the time being my work around has been to use some UI scripting. I don't know if this will be of any use to you but you could give these a try.
tell application "Illustrator CS"
activate
tell application "System Events"
tell process "Illustrator CS"
key down command
key down option
keystroke "p"
key up command
key up option
delay 1
keystroke tab
keystroke "300" --Your measurements in ruler units… not points as the rest of illustrator scripting
keystroke tab
keystroke "300" --Your measurements in ruler units… not points as the rest of illustrator scripting
keystroke return
end tell
end tell
end tell
tell application "Illustrator CS"
activate
set docRef to the current document
tell docRef
if color space of docRef is not CMYK then
tell application "System Events"
tell process "Illustrator CS"
tell menu bar 1
click menu item "CMYK Color" of menu "Document Color Mode" of menu item "Document Color Mode" of menu "File"
end tell
end tell
end tell
end if
end tell
end tell
