Creating and Using Layers (OCGs) with Acrobat JavaScript Thom Parker – Mar 12, 2006 In Acrobat, the term 'Layers' refers to Optional Content Groups (OCGs). OCGs are a mechanism for selectively controlling the visibility of page content. In Acrobat 7 (Professional and Standard) it is possible to both create and control these content layers through JavaScript, giving the document developer a totally new ability to use dynamic content purely through scripting tools already available in Acrobat Professional. This is not another kind of form field or annotation, but true page content. OCGs are used to create multilayer pages (like a stack of transparencies), for everything from multi-language documents, layered views for architectural plans, to animated displays.

What’s New with Acrobat 8 JavaScript Thom Parker – May 7, 2007 With each previous version of Acrobat, the JavaScript DOM (Document Object Model) has improved by leaps and bounds. The DOM is the set of objects that expose Acrobat functionality to JavaScript. JavaScript was introduced in Acrobat 3.02 with a paltry seven objects. Acrobat 4.0 cleaned up and filled out the basic functionality. Acrobat 5.0 super-charged the DOM with the addition of Application Level services like ODBC access, text to speech, security and digital signatures, as well as increasing the functionality of existing objects. Acrobat 6 introduced advanced services like SOAP, multimedia, OCG, toolbar buttons and full custom dialogs. Acrobat 7 added XML processing and two new JavaScript DOMs — XFA (LiveCycle) and 3D.

JavaScript in Batch Processing Thom Parker – Jul 13, 2006 Batch processing works great until you want to do something that either needs more flexibility or isn’t in the list at all. What do you do then? The answer is provided by one of the common commands built into Acrobat, the “Execute JavaScript” command. Scripting greatly increases the number of operations that Batch Processing can apply to a document. It includes, of course, everything that can be done with JavaScript and adds intelligence to how operations are applied to a PDF.

Entering scripts for form fields Thom Parker – Sep 18, 2006 Form-field scripts can be divided into two areas: scripts associated with actions performed on the instance of a field on a page (also called Widget scripts — a specific instance of a field is called a Widget), and scripts associated with the value of a field.

Using Unicode Text Thom Parker – Nov 19, 2006 In JavaScript version 1.3 and later all strings are stored internally as Unicode. This built-in Unicode support gives document developers instant access to a whole world of characters not available on the keyboard or in special font sets like Wingdings or Symbols. In fact, nearly every character set ever used, including Klingon, has a Unicode encoding. Topics: Enhance PDF using JavaScript Products covered:		858		11/19/2006
Entering Document Actions Thom Parker – Aug 15, 2006 Document Actions are JavaScript events triggered by printing, saving, and closing the PDF. These Actions give developers the opportunity to change the PDF before and after one of these activities (except for closing). Some uses for these actions are making a stamp visible before printing, changing a date field before saving, or shutting down a timer when the document is closed.

Building PDF Reports with JavaScript Thom Parker – May 18, 2006 Acrobat JavaScript contains a range of functions and properties for analyzing both a PDF and the Acrobat environment. But how do you display the results of an analysis? The answer is the Report Object. This object creates simple text based PDF files. It’s not fancy, but it does provide a critical resource for presenting information in an easy to read and savable format. Topics: Enhance PDF using JavaScript Products covered:		642		05/18/2006
Popup menus, Part I Ted Padova – Feb 27, 2007 In a previous article in this series on PDF interactivity, I talked about using bookmarks to navigate a collection of PDF files. In this article, I’ll discuss an alternative to bookmarks--popup menus that perform a similar task for document and page navigation.

Finding Page Boundaries Thom Parker – Sep 9, 2006 To script activities such as creating form fields and resizing pages it is necessary to know the dimensions of a document page. In PDF this can be a bit confusing because pages are bounded by several different Page Boxes. Topics: Enhance PDF using JavaScript Products covered:		582		09/09/2006
Entering Page Actions Thom Parker – Aug 19, 2006 Page Actions are triggered by the opening and closing events on a PDF page in the viewer. These Actions are primarily useful for starting and stopping page related interactive features such as multimedia, timers, and animations, but the way in which these actions can be used is only limited by the imagination of the document developer.
