Passing Arguments From Extendscript to AppleScript

Mind sharing some more info about your solution?  I'm very familiar with AppleScript but not ExtendScript and need to execute this exact thing.  Just not sure how the AppleScript receives the parameters set by the ExtendScript.

Thanks!

Most user are Windows users and Most Mac photoshop User that script Photoshop use  JavaScript because it works cross platforms.  I have never even look at AppleScript documentation.  I have seen Photoshop JavaScripts like Image Processor.jsx that pass arguments to the Photoshop Plug-in Fit Image which also happens to be implemented in JavaScript since CS2 or CS3.   To be able to pass arguments to something the something must be coded to process arguments that are pass someway.   How does the external AppleScript get executed and how is it coded to process arguments that may be passed to it.  

Fit Image is a Photoshop Script that happens to be a Photoshop Plug-in.  If it is not passed argument settings it will display a dialog and get the Arguments from user interaction in its dialog.  And If its is being recorded into an Action step the script will record the arguments the user set into the Action Step.  When that Actions is Played the Action Manager will Pass the recorded argument in the action step to the plug-in script.  The script will bypass displaying its dialog and use the passed arguments.

How does your AppleScript Process Arguments and how should the argements be passed.

Here is how Image Processor passes arguments to Fit Image

FitImage( this.params["tiffw"], this.params["tiffh"] ); 

// use the fit image automation plug-in to do this work for me
function FitImage( inWidth, inHeight ) {
	if ( inWidth == undefined || inHeight == undefined ) {
		alert( strWidthAndHeight );
		return;
	}
	var desc = new ActionDescriptor();
	var unitPixels = charIDToTypeID( '#Pxl' );
	desc.putUnitDouble( charIDToTypeID( 'Wdth' ), unitPixels, inWidth );
	desc.putUnitDouble( charIDToTypeID( 'Hght' ), unitPixels, inHeight );
	var runtimeEventID = stringIDToTypeID( "3caa3434-cb67-11d1-bc43-0060b0a13dc4" );	
	executeAction( runtimeEventID, desc, DialogModes.NO );
}

Note: The Plug-in is run by the Action manager code the That Passes arguments to the Plug-in using the Plug-in UUID.

It is not done by throwing the plug-in file over the wall to the OS file system file association like this

var appleScriptFile = new File("~/Desktop/AppleScript.app");
appleScriptFile.execute();
