index colour

[Guest]

HI

I have what seems on the face of it to be an easy task. I need to convert rgb tiffs to index colour. I have created an actioncalled Action 4, consisting of

Convert Mode

  To index color Mode

  Palette: Mac OS system

This runs fine from Photoshop but when I try and script up this action in Applescropt using the routine

tell application "Adobe Photoshop CS"

    activate
   
    do action "Action 4"
   
   
end tell

I get the error  "Adobe Photoshop CS got an error: Illegal argument - argument 2 - Required value is missing"

Anyone got any thoughths about this ???

Try adding the action set that contains "Action 4"

    do action "Action 4" from "whatever set"

Hi

Thanks for the reply and I did try what you had suggested but I am still getting the error. It seems to be happening no matter what action I call from the applescript and I cannot as yet get my head around why

[Paul Riggott]

The action name and actionset are case sensitive, also any spaces before or after the name must be included.

[Muppet Mark]

Both Paul and Mike are correct here you need to include both the action and the set names these are case sensitive so I almost always C&P them out of the double click edit box. I don't however see why you need an action at all? This is directly scriptable like so…

tell application "Adobe Photoshop CS2"

set Doc_Ref to current document

tell Doc_Ref

if mode is RGB then change mode to indexed color with options ¬

{class:indexed mode options, palette:Mac OS system}

end tell

end tell
