 Scripting for Illustrator, a tutorial for Processing coders.
 
-###Intro
+### Intro
 
 I'm going to show you how to create a new document, work with existing documents, make shapes, text, and placed images. I will also show you how to manipulate preexisting objects in a layout. The tutorial assumes you are familiar with basic concepts of object oriented language and the basics of Processing. Naturally, it helps to know the Javascript language, and the basics of Adobe Illustrator. If you are new to the Javascript language (even if you know Java from Processing), here is a nice JS tutorial: http://www.codecademy.com/en/tracks/javascript

 I'm not sure why, but Adobe does not bundle the Illustrator API documentation with ExtendScript or with Illustrator. Here is where to get it: http://www.adobe.com/devnet/illustrator/scripting.html  ...  Download the PDFs called "Illustrator Scripting Reference - JavaScript.pdf" and "Illustrator Scripting Guide.pdf". The guide is an overview of the entire system and how it works, although the language may possibly be developer-centric for an ITPer. The reference is a list of all the objects, describing their properties and methods. A great place to start is page 14. Here is the drawing you see. Don't worry if it's overwhelming information. The API is vast and you don't need to memorize this stuff. Just know that it's there for reference as you work.

 An object model describes which types of things contain other types of things. In this case, the Application object is the top-most, root of the tree. The diagram shows that the Application directly contains TextFont, Document, and those 4 objects on the far right. In the next part of this tutorial, I will show you how to work with the documents. Please think of this as akin to the Processing tutorial on the `background()` and `size()` functions.

 Continuing our discussion of the object model diagram, the Document object, in turn, looks like it directly contains most every kind of thing you would want to create or access, including shapes and art boards. Awesome, so let's work our way down into the cave! Please open the reference PDF (the file you downloaded, called "Illustrator Scripting Reference - JavaScript.pdf") and turn to page 3, the table of contents. Notice it's just a list of object names. Click on "Application" and it will jump to page 8, where it describes the Application object. The description says the following:

 You'll see the system gets confused unless you have a document open in illustrator. If the execution stopped and gave you a red line, try creating a new Illustrator document and leaving it open before running the script again, and it will not error that time.

 If you wish to simply work with the document you already have open, your shortcut is app.activeDocument. However, if you wish to create a new document, here's how we go about it. In the reference, we see the Application has a property called documents, which is an instance of Documents . Click the blue link to Documents and it will jump to page 45, documentation on the collection of Document objects. This object is basically an array of documents. If you have nothing open, the length property will be 0. To create a new document using a pop-up dialog to ask the user what sort of document they need, you can go like this:

I haven't tried this but you could trace, expand, find the path that covers that area, then use its fill-color.
