doc.pageWindowRect and doc.media are undefined in Adobe Acrobat Javascript

Question

I'm using the Javascript API built-in to the Adobe Acrobat products, and trying to access the doc.pageWindowRect attribute.

I originally found that doc.pageWindowRect was undefined whenever I tried to access it, and through various posts on the AdobeUsers forum, found that I needed to activate the media extension first, by running something like console.println(this.media);

Normally this prints a result like: [object DocMedia]

However, on some computers used by our client, this just prints undefined instead. It seems that having this.media remain undefined means that doc.pageWindowRect will stay undefined too.

Does anyone know how to make sure this.media is defined, and thus enable doc.pageWindowRect? Or any other way of getting hold of the doc.pageWindowRect information?

I wondered if there might be a delay in activating the media extension (a suggestion I found online), and have tried repeatedly running code to display this.media and doc.pageWindowRect using app.setInterval, but even after waiting for a couple of minutes, they are still not defined.

Any suggestions would be greatly appreciated.

It seems that having this.media remain undefined means that doc.pageWindowRect will stay undefined too. Does anyone know how to [...] enable doc.pageWindowRect?

pageWindowRect belongs to the multimedia.api plugin. In Acrobat 9 and possibly other versions, this plugin is not by default loaded.

From what I can find in that scenario, one method for loading the multimedia.api plugin is to actually have media in the PDF file.

Default location for this plugin is: %Program Files%\Adobe\Reader 11.0\Reader\plug_ins\Multimedia.api

This might not be the fixing answer, but I hope the suggestion gives some insight. Good luck!
