I'm trying to get pageWindowRect; made a button which does:

console.println(this.pageWindowRect)
console.println(this.docInnerWindowRect)
console.println(this.docOuterWindowRect)
console.println(this.appInnerWindowRect)
console.println(this.appOuterWindowRect)

and returns

undefined
undefined
undefined
undefined
undefined

the example code:

var coords = this.innerAppWindowRect;
console.println(coords.toSource())
// Possible output: [115, 154, 1307, 990]

returns

coords has no properties
8:AcroForm:dQuestionEOB05PC12a1:Annot1:MouseUp:Action1

Any ideas? Are these properties dead and buried?

Backstory: I have bookmarks where fields need to go. I want to get the Y value of the current viewstate to place a field relative to the top of the viewable area. eval(viewState.toSource()).pageViewY is based off some crazy number that goes over 1000 (while valid page coords max at ~792). viewState y values also use top as 0, where rect Y values use the bottom as 0.

You need to get the properties correct and make sure you are using a version of Acrobat/Reader that can provide those properties.

console.println('viewer version number: ' + app.viewerVersion);if(app.viewerVersion < 6) {app.alert('The window rectangle properties are only available for version 6 or above', 0, 0);} else {console.println('pageWindowRect: ' + this.pageWindowRect);console.println('innerAppWindowRect: ' + this.innerAppWindowRect);console.println('outerDocWindowRect: ' + this.outerDocWindowRect);console.println('outerAppInnerWindowRect: ' + this.outerAppInnerWindowRect);console.println('outerDocWindowRect: ' + this.outerDocWindowRect);}

Quote:

viewer version number: 8.101
pageWindowRect: 300,216,1135,830
innerAppWindowRect: 0,46,1152,830
outerDocWindowRect: -4,186,1156,834
outerAppInnerWindowRect: undefined
outerDocWindowRect: -4,186,1156,834

true

Oops. That's embarrassing, but the end result is the same:

viewer version number: 9.1pageWindowRect: undefinedinnerAppWindowRect: undefinedouterDocWindowRect: undefinedouterAppWindowRect: undefinedinnerDocWindowRect: undefined

I'm using 9.1 Pro, and I see that it sees that; I'm at a total loss here.

Current kludge:

pageHeight = 792viewHeight = 1160 //(best guess as to the max Y value from viewState)startY = pageHeight-(((eval(this.viewState.toSource()).pageViewY/(this.zoom/100))/1160)*pageHeight)

It works, well enough for my purposes; but man. pageWindowRect[1] seems like the correct way to address this problem.

With version 9 the documentation shows the use of the 'toSource()' method to convert the object to a string, [url=http://livedocs.adobe.com/acrobat_sdk/9/Acrobat9_HTMLHelp/wwhelp/wwhimpl/js/html/wwhelp.htm?href=JS_API_AcroJSChanges.89.1.php#1515776&accessible=true]innerAppWindowRect[/url].

if(app.viewerVersion < 6) {app.alert('The window rectangle properties are only available for version 6 or above', 0, 0);} else {console.println('viewer version number: ' + app.viewerVersion);console.println('pageWindowRect: ' + this.pageWindowRect.toSource());console.println('innerAppWindowRect: ' + this.innerAppWindowRect.toSource());console.println('outerDocWindowRect: ' + this.outerDocWindowRect.toSource());console.println('outerAppInnerWindowRect: ' + this.outerAppInnerWindowRect.toSource());console.println('outerDocWindowRect: ' + this.outerDocWindowRect.toSource());}

Now once you get these strings you will need to convert them to an array for further processing.

There is always something being changed by Adobe in the Acrobat JavaScript with each new product release.

The problem is that I don't get those strings to begin with, they're undefined. So calling .toSource() just results in a "x has no properties" error.

The documented properties have no value. I'm going to try and test this on an 8.1 system; maybe they completely changed this in 9/9.1

Edit: It works in 8.103 with the same PDF; so they clearly just changed something between the last js_api.pdf update and 9.1. Grumble.

Have you looked at the documentation for Acrobat JavaScript for version 9?

There have been a lot of changes in security, properties, methods, and how objects are being created with each new version of Acrobat/Reader, so one needs to check the new documentation when things no longer work.

See the link that I provided above.

Thanks, I did. Unfortunately it is identical to my offline reference in this regard.

Were you able to resolve this?

I have the same problem.
I am trying to upgrade code from Acrobat 6 to Acrobat9. I used pageWindowRect extensively, but now it says it is undefined.
None of the other windowRect properties work either.

On a related note, does anybody know how to get a PDF file of the Acrobat 9 Javascript reference manual? The HTML pages are terrible.

I was not, I just worked around it. As to an offline 9.1 js API reference, I'm not sure. I've been using the 8.1 reference linked at the top of the forum; but I've been developing for 8.13 so I never noticed it's shortcomings. (Rich Media Annots being one of them)

Thanks for responding .
I'm sure it's security related, but I haven't the foggiest why.
If I find an answer I will be sure to post it.

Any solution to this problem yet? I was using the pageWindowRect property in acrobat 7 and 8 with no problem. Even the latest 9.2 still returns pageWindowRect as undefined although the javascript documentation lists pageWindowRect as a valid property.

pageWindowRect is part of the multimedia.api plugin that , in Acrobat 9.x, does not get loaded by default. As far as I know the only way to load that plugin is to actually have some media in the PDF file (but I am not 100% sure about that). Regardless I could not figure out how to force the plugin to load, so I abandoned using pageWindowRect.
Instead I used something similar to what efos wrote about in 2009-05-18 20:09:21 posting.

Rob's right, but it's easy to get it to load. For example:

console.println(this.media);
app.alert(innerAppWindowRect);

Thanks for the quick info. I see how this easily helps when you're executing the Javascript in the document, but I wasn't able to figure out how I can achieve this using C# and JSObject.

Here's what I was doing to get the page dimensions

object acroJSObject = acroPDDoc.GetJSObject();object[] screenRect = (object[])acroJSObject.GetType().InvokeMember("pageWindowRect", BindingFlags.GetProperty, null, acroJSObject, null);Rectangle pageRect = new Rectangle(Convert.ToInt32(screenRect[0]), Convert.ToInt32(screenRect[1]), Convert.ToInt32(screenRect[2]), Convert.ToInt32(screenRect[3]));

I've tried adding a line to instantiate the media object but it didn't help or I'm not doing it right.

Chuck,

You should be able to use the JSObject to execute that first line of code I showed, though I don't know how to do it in C#.

Hi Chuck,

I had the same issue in C#.
So I did not use invoking javascript but used their .net library.

AcroPDPage p = doc.AcquirePage(0);
AcroPoint pp = p.GetSize();

int a = pp.x;
int b = pp.y;
