Working Float Pallete in Photoshop and Illustrator

• As mentioned above, Pallete is ideal choice for tool panel design, as dialog prevent main App interaction until close, but Pallete is closed automatically after script code finished, thus we need following solution to work around Pallete limit in Photoshop and Illustrator
• use BridgeTalk object as message to send to the Application instead ask the Application to create window. so the Message stands as its own thread
  • ref:
    • http://www.davidebarranca.com/2012/10/scriptui-window-in-photoshop-palette-vs-dialog/
    • http://www.davidebarranca.com/2012/11/scriptui-bridgetalk-persistent-window-examples/
• sample code, change target to your application, the script can be launch from any Adobe app, but only the target will receive it, as it is like a letter with receiver name, all Adobe app will pass the message to the Target.

  ui_pallete_BT.jsx

  function WinObject() {
    var win_type = "palette";
    var ui = win_type+" {orientation: 'column',alignChildren: ['fill', 'top'],preferredSize:[300, 130],text: 'Title Here',margins:15,";
      var slider_panel = "slider_panel: Panel {orientation: 'row',alignChildren: 'right',margins:15,text: 'Panel Title',";
          slider_panel +="value_label: StaticText { text: 'Value:' },";
          slider_panel +="value_slider: Slider { minvalue: 1, maxvalue: 100, value: 30, size:[220,20] },";
          slider_panel +="value_edit: EditText { text: '30', characters: 5, justify: 'left'}";
          slider_panel +="}";
      ui+=slider_panel;
      var btm_grp = "btm_grp: Group{";
        btm_grp +="value_check: Checkbox { text:'Checkbox value', value: true },";
        btm_grp +="cancel_btn: Button { text: 'Cancel', properties:{name:'cancel'}, size: [120,24], alignment:['right', 'center'] },";
        btm_grp +="apply_btn: Button { text: 'Apply', properties:{name:'ok'}, size: [120,24], alignment:['right', 'center'] },";
        btm_grp +="}";
      ui+=btm_grp;
      ui +="}";
    var win = new Window(ui);
    win.btm_grp.cancel_btn.onClick = function() { win.close() };
    win.btm_grp.apply_btn.onClick = function() { win.close() };
    win.show();
  }; 
  var message = WinObject.toString();
  message += "\nnew WinObject();"
  var bt = new BridgeTalk();
  //bt.target = "aftereffects";
  bt.target = "photoshop";
  //bt.target = "illustrator";
  bt.body = message;
  bt.send();

• thus, BridgeTalk is good solution for inter-Adobe app communication.

  call_ps_from_ai.jsx

  // the BridgeTalk Object
  var bt = new BridgeTalk();
  // the communication target
  bt.target = "photoshop";
  // The script to be executed as a String
  var message = "alert('Hello Photoshop')";
  // assign to the object's body the message
  bt.body = message;
  // send the message to the target app
  bt.send(); // an alert will pop-up in Photoshop

One-For-All solution with BridgeTalk for Working Float Pallete

• As BridgeTalk is the key for working float pallet, but in a BridgeTalk, the target App is pre-defined in the script, like bt.target=“Photoshop”, and also the whole script is wrapped in a message,
• The One-For-All solution is use BridgeTalk to launch existing normal-styped javascript jsx file, so the main function and launcher are separated into 2 files,
• example code as below

  launch_js_for_ps.jsx

  var script_name = "ui_demo.jsx";
  var currentPath = (new File($.fileName)).path; // retrieve the current script path
  var scriptToLoad = new File (currentPath + "/"+script_name); // the script to load
  try {
      if (!scriptToLoad.exists) { throw new Error("script not found!"); }
      scriptToLoad.open ("r"); // read only
      var message = scriptToLoad.read();
      scriptToLoad.close();
  } catch (error) {
      alert("Error parsing the file: " + error.description);
  }
  var bt = new BridgeTalk();
  bt.target = "photoshop";
  bt.body = message;
  bt.send();

Special Note for BridgeTalk Method

• use “\” way of ui coding will cause BridgeTalk method's button callback not working, thus the window resource string can't contain backslashes “\”
• jsxbin is jsx in binary encoded (which can be exported from jsx in ExtendScript TookKit); the message also can take binary string and embed your script in the BridgeTalk object.
  • example code (\ added for each line from original ui_demo.jsxbin)

    ui_demo_inBinary.jsx

    var message = "@JSXBIN@ES@2.0@MyBbyBn0ATJAnASzIjXjJjOifjUjZjQjFByBneHjQjBjMjFjUjUjFftJCnASzCjVj\

Quick Introduction

• Javascript Scripting in Photoshop is introduced in Photoshop 7, however Photoshop 5-7 support COM script
  • it is based on javascript 1.5 (2000) and new featured added, so modern javascript functions may not included.
• Javascript is cross-platform but is control Photoshop only, unlike VBscript and AppleScript controls any AppleEvents or windows COM supported application.
  • For com, it is like

    app = createObject("Photoshop.Application.versionNum")

• download scripting guide cs2-cc: http://www.adobe.com/devnet/photoshop/scripting.html
• ref:
  • http://jongware.mit.edu/pscs5js_html/psjscs5/

• variable type
  • string, number, boolean, null, object, undefined
• variable store
  • value, object reference
• other
  • command and methods

Advance scripting Start Kit

• Get XToolkit 2.2 from : http://ps-scripts.sourceforge.net/xtools.html
  • a javascript standard library to get modern javascript functions and extras for photoshop functions
  • a console to test script: JShell
  • a list of utility to convert Photoshop asssets

• for cs3 till cs6, the flash panel is supported, but it won't work in CC since they move into html5,
  • anyway, the flash panel is no good, since it is a dialog, it block interactivity until you close.
  • here is where you can still find it, FlashUISample.jsx and related: https://github.com/tahoedesigner/ExtendScript/tree/master/Adobe%20Sample%20Scripts
• for cs5 and above, the Plug-ins\Panels is there for plugin panels, then the Windows > Extension to show the panels

• for photoshop CS5 and above, there is Adobe Configurator to create custom panel without code
  • https://www.youtube.com/watch?v=d_rMfjatX-M
  • download of adobe configurator: http://labs.adobe.com/technologies/configurator/
  • additional notes:
    • from adobe configurator 4, it moves fully to HTML5-based panels, also extension builder 3 also move to HTML5-based panels

• Develop HTML Panels for Adobe CC apps: Extension Builder (or just a text editor)
  • download: http://labs.adobe.com/technologies/extensionbuilder3/
  • example: http://www.adobe.com/devnet/creativesuite/articles/a-short-guide-to-HTML5-extensions.html

• other tools using custom panel:
  • Export kit: http://exportkit.com/lightning-storm-cc

• More news on CC version and above:
  • https://medium.com/@HallgrimurTh/extending-adobe-cc-2014-apps-ba1d101e27da#.cduf21vml
  • http://adobe-cep.github.io/CEP-Resources/

• other example project
  • cc based panel let u list jsx file and run: https://github.com/moremorefor/JSXExecutor

• so conclusion, if you are not stuck with old technology, and you willing to move to adobe CC version, HTML5 is the way to go for all new techs instead of Python fighting into adobe apps.
