scaling images with image events, but with conditional statement

Scripting Forums AppleScript | Mac OS X

I can’t figure this one out. I get all sorts of error of wrong “type”.

Here is the basic script (which I got from Apple’s site)


property type_list : {"TIFF", "JPEG", "PNGf", "PICT"}
property extension_list : {"tif", "tiff", "jpg", "jpeg", "png", "pict", "pct"}

tell application "Finder"
	activate
	try
		set these_items to the selection
		repeat with i from 1 to the count of these_items
			set this_item to item i of these_items
			if the file type of this_item is in the type_list or ¬
				name extension of this_item is in the extension_list then
				set this_path to this_item as string
				tell application "Image Events"
					set this_image to open file this_path
					-- IMAGE PROCESSING STATEMENTS GO HERE
					--get dimensions of this_image
					scale this_image to size 640
					save this_image with icon
					close this_image
				end tell
				-- FINDER ACTIONS SUCH AS MOVE, DUPLICATE, OR DELETE GO HERE
			end if
		end repeat
	on error error_message
		display dialog error_message buttons {"OK"} default button 1
	end try
end tell

So, the place where I’ve put get dimensions is where I have problems.

I tried
if dimensions of this_image is greater than 640 then

It gives me the Type error.

If I tried to get the dimensions. It works, but returns a list of two items. I’ve tried getting the items of the list by setting them individually like this.

set my_width to (item 1 of dimensions of this_image)

I tried to put as string at the end and still get an error message.

I know this must be super easy, but I can’t figure it out. All I want to do is to scale the image only if one of it’s sides is larger then 640.
