Set zoom in CS5

We've been using the below Java code to set the zoom of a document in Photoshop 7 (yeah, I know - ancient) to fit the screen (like hitting Ctrl + 0 on the PC) but it no longer works in CS6. The runMenuItem command is generating "Error 1242: Illegal argument - argument 1."

function runMenuItem(item){ // from xbytor
cTID = function(s) { return charIDToTypeID(s); };
var desc = new ActionDescriptor();
var ref = new ActionReference();
ref.putEnumerated( cTID( "Mn  " ), cTID( "MnIt" ), cTID( item ) );
desc.putReference( cTID( "null" ), ref );
executeAction( cTID( "slct" ), desc, DialogModes.NO );
}
runMenuItem("FtOn");// fit on screen ( same as ctrl-0 )

Is there some other way this can to be done in CS6?

Thanks,

Ken

Correct answer Michael_L_Hale
app.runMenuItem(charIDToTypeID(("FtOn")));

Newer versions of Photoshop have an application method for calling menu items.

These scripts work in CS6 (at the very least), and will set your zoom levels to 6.25, 8.33, 12.5, 50, 66.67, 100, 200 respectively.

6.25%

function getScreenRes(){


   var ref = new ActionReference();


   ref.putEnumerated( charIDToTypeID("capp"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") ); 


   return executeActionGet(ref).getObjectValue(stringIDToTypeID('unitsPrefs')).getUnitDoubleValue(stringIDToTypeID('newDocPresetScreenResolution'))/72;


}


function setZoom( zoom ) {


   cTID = function(s) { return app.charIDToTypeID(s); };


   var docRes = activeDocument.resolution;


   activeDocument.resizeImage( undefined, undefined, getScreenRes()/(zoom/399.7), ResampleMethod.NONE );


   var desc = new ActionDescriptor();


   var ref = new ActionReference();


   ref.putEnumerated( cTID( "Mn  " ), cTID( "MnIt" ), cTID( 'PrnS' ) );


   desc.putReference( cTID( "null" ), ref );


   executeAction( cTID( "slct" ), desc, DialogModes.NO );


   activeDocument.resizeImage( undefined, undefined, docRes, ResampleMethod.NONE );


} 


setZoom (25);

Now if we could just set the keycenter value...

That worked perfectly Michael, thanks so much.

I did a quick search but didn't find anything by way of a list of these. I found one reference that mentioned a PDF in which the ScriptListener was described. I've download it and am about to give it a try.

Do you know if there IS, indeed, a list of these somewhere?

Again, many thanks,

Ken

There are a couple of lists but I think the best way to find the IDs you need is to use the scriptlistener plug-in for things that can be recorded to the log. Some things don't log, so for those you can try using 'insert menu item' in an action, save the action, then either look at the action file with an hex editor or use xbytor's xtools to convert the action file to javascript.

Here is a list of view related IDs

charIDToTypeID("FtOn"); // fit window
charIDToTypeID("ActP"); // actual pixels
charIDToTypeID("ZmIn"); // zoom in
charIDToTypeID("ZmOt"); // zoom out
stringIDToTypeID("screenModeFullScreen"); 
stringIDToTypeID ("screenModeStandard");
stringIDToTypeID( "screenModeFullScreenWithMenubar" );
