Zoom in and resize window?

[jonohunt]

I found an existing script to zoom in (to whatever level you set it at) with the current image/document.

main();
function main(){
// Change the value between the parentheses below
// into your desired percentage:
setZoomLevel(500);
// Leave the code below unchanged
function setZoomLevel(zoom){
if(zoom < 1) zoom =1;
var ref = new ActionReference();
ref.putEnumerated(charIDToTypeID(\"capp\"), charIDToTypeID(\"Ordn\"), charIDToTypeID(\"Trgt\"));
var getScreenResolution = executeActionGet(ref).getObjectValue(stringIDToTypeID('unitsPrefs')).getUnitDoubleValue(stringIDToTypeID('newDocPresetScreenResolution'))/72;
var docResolution = activeDocument.resolution;
activeDocument.resizeImage(undefined, undefined, getScreenResolution/(zoom/100), ResampleMethod.NONE);
var desc = new ActionDescriptor();
ref = null;
ref = new ActionReference();
ref.putEnumerated(charIDToTypeID(\"Mn  \"), charIDToTypeID(\"MnIt\"), charIDToTypeID('PrnS'));
desc.putReference(charIDToTypeID(\"null\"), ref);
executeAction(charIDToTypeID(\"slct\"), desc, DialogModes.NO);
activeDocument.resizeImage(undefined, undefined, docResolution, ResampleMethod.NONE);};};

I'm wondering if it's possible to modify the script so that it also resizes the window when zooming?

i.e. the equivalent on pressing Command Option = or checking 'Zoom Resizes Windows' in Photoshop's preferences.

Zooming changing Photoshop image windows size is a Photoshop preference. You can set it either way in and actions and scripts. And you can use menu items in actions and scripts like the zoom in and zoom out and view actual pixels. Some other menu items also change Photoshop image windows size like fit on screen  and full screens mode.
