Geometry in InDesign can get deadly complex. Take a document, create a frame, insert a table, change a particular cell into a “graphic cell,” convert its inner object into an ellipse, play with strokes, rotate and scale the object, transform the parent frame in the fanciest way. Then ask yourself the question: what are the exact coordinates, shape or area of the final table cell?…

The Case of Converting InDesign Inches to Ciceros
July 26, 2022 | Tips | en
While working on his Measurements scripts, my colleague Mikhail Ivanyushin reported me weird biases related to units conversion. In particular, he observed a discrepancy between InDesign's display and direct results from ExtendScript when addressing inches-to-ciceros translation…
The Hard Problem of Quantified Alternatives in ExtendScript
January 21, 2022 | Tips | en
In most cases, ExtendScript regular expressions cannot digest the (a|b)+ scheme. This bug is not new, but it's worth defining its symptoms and extent. This article presents a very simple problem, with no known solution to date…
Porting your InDesign Script into IdExtenso — Step 5
October 19, 2021 | Tips | en
In this episode we seriously improve the relationship between user settings and user interface. As a result, we get a smart InDesign script that both remembers the choices the user made within the session and adapts to the context, that is, whether the script should target the selection or a larger scope…

Coordinate Spaces & Transformations is a free eBook covering all atomic subjects that a InDesign scripter or developer should grab before using transformation matrices and the related methods. The last update has minor corrections and notes…
Porting your InDesign Script into IdExtenso — Step 4
October 09, 2021 | Tips | en
The previous episode dealt with modularity in IdExtenso, now is the time to take full advantage of it! Today we will see how to add a dialog interacting with user options. You will be amazed at how quickly this component fits into the script…
Porting your InDesign Script into IdExtenso — Step 3
September 24, 2021 | Tips | en
In this episode, you will learn how to arrange your code so that it fits into IdExtenso's “modular space.” Modularity is a key term when it comes to maintaining a large-scale project. Even if our sample script is not in itself of pharaonic complexity, we will transform it, as an exercise, into a pure module…
Porting your InDesign Script into IdExtenso — Step 2
September 15, 2021 | Tips | en
Today we will embed in IdExtenso the code we prepared in the previous episode. That's of course an important move, especially when you perform it for the very first time (since then you need to install the framework.) But you will discover in what follows the immediate advantages that $$ offers you…
Porting your InDesign Script into IdExtenso — Step 1
September 07, 2021 | Tips | en
So, you have the root idea and a basic code for your next InDesign script. All is fine. It works so well that you're now planning to release it, which opens additional questions: Will it work everywhere? How do I trace risky functions? What if I need to integrate new features later on? How do I deal with persistent user settings? How to add a basic interface? How will I localize the dialog in other languages? Can I make my script available in a dedicated menu? Will it work in a JSXBIN package as well? Can I obfuscate my code?…
Page Range Formatter [UPDATE]
August 17, 2021 | Tips | en
Given an unordered set of page numbers—e.g. {13, 9, 25, 12, 11, 8}—we often have to compute and output a range specification in the form "8-9; 11-13; 25". While this topic has been already discussed in the InDesign scripting forum, I'd like to explore today a slightly different approach…
ScriptUI vs. UI Scaling
March 08, 2021 | Tips | en
From CC 2014, InDesign and Illustrator interfaces needed to adapt to OS “scale settings” strategy on 4K/Retina displays. And with Windows 10 defaultly scaling at 150% in such resolutions, Adobe engineers were forced to rework their famous HiDPI support, which led to introduce UI Scaling in the Preferences dialog box. So far, so good. But ScriptUI has not been fully “informed” of these new rules…
Understanding the `count( )` Method
November 13, 2020 | Tips | en
InDesign's scripting infrastructure is based on DOM objects (Document, Story, Paragraph…) and any such object has an associated collection (Documents, Stories, Paragraphs…). Collections typically arise in complex specifiers like myDocument.stories.everyItem().words. They also provide two essential members, the length property and the count() method. How do they differ?
The Tricky Side of `string.replace( )` in ExtendScript
September 14, 2020 | Tips | en
When you invoke myString.replace(...) in pure JavaScript, the “string being examined” is and remains myString during the whole operation. ExtendScript offers a slightly different mechanism that may unexpectedly alter the output string…
Why You Should Never Use `x==null` in ExtendScript
May 13, 2020 | Tips | en
The Japanese scripter あるふぁ found a bug affecting any ExtendScript code based on ...==null. This is not a critical issue (because experienced developers never use such condition!) but the case provides the opportunity to summarize important rules regarding falsey values and the equality operator…
How To Get parseInt( ) Fixed in ExtendScript
January 10, 2019 | Tips | en
The global method parseInt(str,radix) has a critical bug in ExtendScript. When radix is greater than 10, some undesired characters can be mistakenly parsed as valid digits, which corrupts the output. This issue is solved in IdExtenso…
Note on ScriptUI Mouse Events
December 19, 2018 | Tips | en
ScriptUI provides a set of usual mouse events (mouseover, mousedown, mouseup, click…) which are of primary interest in responsive user interfaces (UI). Developers can add event listeners to any UI component that needs to respond accordingly when the mouse enters the scene. But handling such events requires carefulness if your script has to support both CS and CC environments.
SelToPng | Quick InDesign-to-PNG Serializer
