Изменение скрипта Adobe Photoshop

Question

Я нашел этот скрипт для создания значков iOS в Интернете, и я хочу его отредактировать, чтобы он работал с открытым файлом, а не файловым файлом (язык программирования). Я создаю инструмент с конфигуратором Adobe 4, чтобы ускорить процесс создания значков.

try 
{ 
// Prompt user to select iTunesArtwork file. Clicking "Cancel" returns null. 
var iTunesArtwork = File.openDialog("Select a sqaure PNG file that is at least 1024x1024.", "*.png", false); 

if (iTunesArtwork !== null) 
{ 
var doc = open(iTunesArtwork, OpenDocumentType.PNG); 

if (doc == null) 
{ 
    throw "Something is wrong with the file. Make sure it's a valid PNG file."; 
} 

var startState = doc.activeHistoryState;  // save for undo 
var initialPrefs = app.preferences.rulerUnits; // will restore at end 
app.preferences.rulerUnits = Units.PIXELS;  // use pixels 

if (doc.width != doc.height) 
{ 
    throw "Image is not square"; 
} 
else if ((doc.width < 1024) && (doc.height < 1024)) 
{ 
    throw "Image is too small! Image must be at least 1024x1024 pixels."; 
} 
else if (doc.width < 1024) 
{ 
    throw "Image width is too small! Image width must be at least 1024 pixels."; 
} 
else if (doc.height < 1024) 
{ 
    throw "Image height is too small! Image height must be at least 1024 pixels."; 
} 

// Folder selection dialog 
var destFolder = Folder.selectDialog("Choose an output folder"); 

if (destFolder == null) 
{ 
    // User canceled, just exit 
    throw ""; 
} 

// Save icons in PNG using Save for Web. 
var sfw = new ExportOptionsSaveForWeb(); 
sfw.format = SaveDocumentType.PNG; 
sfw.PNG8 = false; // use PNG-24 
sfw.transparency = true; 
doc.info = null; // delete metadata 

var icons = [ 
    {"name": "iTunesArtwork@2x", "size":1024}, 
    {"name": "iTunesArtwork", "size":512}, 
    {"name": "Icon",    "size":57}, 
    {"name": "Icon@2x",   "size":114}, 
    {"name": "Icon-72",   "size":72}, 
    {"name": "Icon-72@2x",  "size":144}, 
    {"name": "Icon-Small",  "size":29}, 
    {"name": "Icon-Small@2x", "size":58}, 
    {"name": "Icon-Small-50", "size":50}, 
    {"name": "Icon-Small-50@2x", "size":100} 
]; 

var icon; 
for (i = 0; i < icons.length; i++) 
{ 
    icon = icons[i]; 
    doc.resizeImage(icon.size, icon.size, // width, height 
        null, ResampleMethod.BICUBICSHARPER); 

    var destFileName = icon.name + ".png"; 

    if ((icon.name == "iTunesArtwork@2x") || (icon.name == "iTunesArtwork")) 
    { 
    // iTunesArtwork files don't have an extension 
    destFileName = icon.name; 
    } 

    doc.exportDocument(new File(destFolder + "/" + destFileName), ExportType.SAVEFORWEB, sfw); 
    doc.activeHistoryState = startState; // undo resize 
} 

alert("iOS Icons created!"); 
} 
} 
catch (exception) 
{ 
// Show degbug message and then quit 
if ((exception != null) && (exception != "")) 
alert(exception); 
} 
finally 
{ 
if (doc != null) 
    doc.close(SaveOptions.DONOTSAVECHANGES); 

app.preferences.rulerUnits = initialPrefs; // restore prefs 
}
