Creating an empty sheet in an existing PDF and adding a watermark

Posted on 2014-04-15
Last Modified: 2014-04-17
Hi experts.  Want to know how to VFP9 programmatically insert a blank pdf sheet in an existing PDF file (as the first page) and put a watermark "Confidential stamp" on it.  I already use that portion of code, but do not succeed to insert a blank sheet so far:

lo = createobject("AcroExch.App")
oNew = createobject("AcroExch.PDDoc")"C:\test.pdf")
oNew.InsertPages(-1,oNew,0,oNew.GetNumPages(),1)  && this insert a copy of first page, not empty page...

Can you be of any help ?

Refer to the documentation.

Inserts the specified pages from the source document after the indicated page within the current document.

So the method isn't there to insert blank pages, it inserts pages (one page) of the oNew document to the oNew document, because you specify so in the parameters.

You need a blank page PDF and load it as oBlank=createobject("AcroExch.PDDoc")"C:\blank.pdf"), then you can insert that.

Exact, I found this a few hours ago.  Since I'm trying to either change a text on a "controlled inserted page" or adding a watermark.  So far no success.  Any ideas ?

I already proopsed an idea, didn't I?

Open Word or Wordpad, print a new empty document as PDF and you have a blank.pdf you can use to insert into your other PDFs.

Sorry, I gave a bad explanation of my understanding :(   This is exactly what I've done: printed an empty WordPad into PDF.  This gave me the possibility to insert a white page.  Next step is to programmatically either edit a previously saved Watermark or create a new one.  I already found how to get a previouslay saved watermark

acroAvDoc = CREATEOBJECT("AcroExch.AVDoc")
acroPDDoc = acroAVDoc.GetPDDoc
acroRect = CREATEOBJECT("AcroExch.Rect")
PDTextSelect = acroPDDoc.CreateTextSelect(0,acroRect)

From that point, I have watermark text but did not fnd so far how to replace it by something else...  At this point, I'm not even sure I could do it :(

I don't know the AcroExch API, I just could google again, what it offers.

The simplest method would be to delete the previous empty/watermark page and create a new one, wouldn't it? If there is InsertPages, isn't there DeletePages, too?

Bye, Olaf.

Yes, but I manually wrote watermark, not programmatically.  I was thinking by manually position it, font it, orient it and so on it would be easier to "just change text" after: obviouly not !   At this point, if I can't "just change text", my turn around would be to create a VFP report, fill it with table's data and make it PDF so that will be the "inserted page".

Indeed, or write it in Word/Wordpad and create the "watermark.pdf" to insert, which can also be done by Word automation, for example.
