Photoshop Script Boilerplate Code on GitHub

Back when I started writing Scripts for Photoshop, I'd have loved having Boilerplate code to borrow and learn from. I've put a repository on GitHub with my take on that - still in early, alpha stage but some CoffeeScript stuff is there, ready to be forked: feel free to contribute!

Photoshop CC Color Range Enhancements

Latest Photoshop CC update (version 14.1) has introduced a good deal of new features. One of them is the refined Color Range Selection for Highlights, Midtones and Shadows which now includes Threshold: let's see what is that all about.

ScriptUI tip: decoupling components’ Event handling

In a ScriptUI Window different components are usually registered for Events, and fire their own Handlers. You can build some interconnection, so for instance a Button's 'click' handler triggers a change in a ListBox, which in turn reacts to its own 'onChange' Event. It's quite easy to decouple this interaction, provided that you set up your code properly.

Testing minified JS Libraries in ExtendScript

It's not uncommon, when scripting for Adobe applications, to borrow JS libraries that have been originally written for web development. While the new generation of Adobe HTML Extensions will run on the Chromium Embedded Framework, traditional ExtendScript code is based upon a different, older engine. Besides ECMAScript unsupported features (i.e. ES 5) I've noticed that using minified JS code is a risky business - scripts can break or fail silently. I've set up a proper testing environment to inspect them.

ScriptUI Events: call(), dispatchEvent(), notify()

In your code you may need to run a ScriptUI component's callback, or simulate a user interaction, maybe as a part of a subroutine. There are few ways to do this, with slight differences in the behavior: directly, using call(), notify() or dispatchEvent() - I've set up a commented demo Dialog that shows them all.
