Using the SDK and this.addWatermarkFromFile method works with the pdf supplied with the SDK, but when gererating a new PDF via Microsoft" Print To PDF or with Acrobat create new from file Word document it doesn't work. It doesn't add the stamp at all.

The method addWatermarkFromText works fine, but I need to add an image.

If I do it manaully through Acrobat using the same files, it works fine.

Any suggestions?

Acrobat SDK and JavaScript

Is the file secured or digitally signed, by any chance?

If I do this in my powershell for the source PDF that works, then $temp returns System._ComObject.
If I do this for Sample2Portrait.pdf, then $temp is empty.

$AForm = New-Object -ComObject AFromAut.app

$temp = $AForm.Fields;

write-host($temp)

Well, SamplePDF01.pdf contains a form definition (the PDF actually contains a text field with the text "This is the latest document submitted for review. 8/30/2004") but Sample2Portrait.pdf does not. This might explain your observation.

Interestingly, though, Test2.pdf does contain a form definition.

So it looks like $AForm.Fields implicitly creates a form definition (if none was there) but does not return an object representing it. Have you tried fetching $AForm.Fields a second time if it was empty the first time? Is the second result still empty?

SamplePDF01.pdf is the supplied file from SDK which works.
Sample2Portrait.pdf is the file generated from Word with Microsoft: Print To PDF

Test1.pdf is the resulting file from the below code using SamplePDF01.pdf as my input

Test2.pdf is the resulting file from the below code using Sample2Portrait.pdf

Here is my code:

$app = New-Object -ComObject AcroExch.App
$PDDoc = New-Object -ComObject AcroExch.PDDoC
$PDDoc.Open("C:\Users\100620\Documents\Derived Output\PDF Mastership\SamplePortrait.pdf")
$AVDoc = $PDDoc.OpenAVDoc("")
$AForm = New-Object -ComObject AFormAut.App
$AForm.Fields.ExecuteThisJavascript("this.addWatermarkFromFile('../../../../temp/Box.pdf');")

$NewDoc = $PDDoc.Save(1, "C:\Users\100620\Documents\Derived Output\PDF Mastership\Test2.pdf")

$app.CloseAllDocs();
$PDDoc.Close();
