Hi Mat,
Yes I did try that, but its a Catch-22 situation.  I needed to make the Watermark transparent enough so I can still see the text/images behind it, but not too transparent that the Watermark is hard to read.
 
I could not find a suitable compromise between these two conflicting requirements which is why it MUST be placed behind the text/images.

I wonder can you achieve similar effect by adjusting the watermark transparency.

As Andrew mentioned in his previous post, the reason it wasn't working was that the first command in the PDF File was to draw a white rectangle.
 
This can be found using GetPageContentToString (or GetPageContentToVariant - ActiveX version) and you will see something like this at the top of the file.
 

1 g                                   // select White -

0 2.66797 4956 7014 re // create a rectangle

f                                     // fill the rectangle with the white pen

 
And the reason for this was I was printing the PDF indirectly through a Web-based application and not directly through the PDFCreator application.

Ha! Ha! That's the exact same link I mentioned above Tongue  My code is based on your example Andrew - it sort of worked for some PDF's but not for others (see my code below).
 
 
If I converted a Word document into a PDF using PDF Creator it worked, however if I used a PDF created from a hospital application and moved it to Stream 1, the watermark didn't even appear!!
 
If I moved it to Stream 2, the Watermark appeared in both PDF's but always infront of the text.
 
In both cases the ContentStreamCount was three.  How do I tell if the first command is to draw and fill a white rectangle - could that be the issue?
 
Unfortunately I can't attach the problematic PDF report because it has patient information on it.

You could try something along the lines of the following which I have adapted from http://www.quickpdf.org/forum/inserting-text-behind-existing-text_topic2570_post10615.html?KW=behind+text#10615

   QP.LoadFromFile (...
   QP.SelectPage(1);
   int cs = NewContentStream();

   QP.SetOrigin(1);

   int img = QP.AddImageFromFile("myimage.png", 0);
   QP.DrawImage(0,0,QP.PageWidth(), QP.PageHeight();

   QP.MoveContentStream(cs, 1);

   QP.SaveToFile("newfile.pdf");

Moving the content stream with the image to content stream 1 will mean that the image is draw first and that any test or other logos will be drawn on top.

Whether this approach works or not will depend on how the PDF is created.  If the first command of the PDF is to draw and fill a white rectangle the same size as the page then this approach will not work.

If this doesn't work then you will need to post some code so we can understand what is and isn't working.

Can my issue be solved using ContentStreams?

Hi Chris!

That's what i told.
But you should try - seems here in the user forum there's nobody doing this before.
If you want to post new user ideas/-requests you should go onto the official pages (have a click on the logo at the top, left).
BTW: Creating a new document there's always one blank page and one layer/contentgroup.

Cheers, Ingo

Hi again,
There was a post that explained how to insert text behind text using Streams (see link) which I thought I could use with my Watermark issue.
 
http://www.quickpdf.org/forum/inserting-text-behind-existing-text_topic2570_post10615.html?KW=behind+text#10615
 
My original PDF seemed to have two ContentStreams and I created a NewContentStream (No. 3) added the image and then used the MoveContentStream function to move it from Stream 3 to Stream 1.  But it didn't matter what streams I moved around or where I added the image (before or after a NewStream was created) the watermark always appeared on top of the original text.
 
Can my issue be solved using ContentStreams?
 
Chris

Damn.  I was hoping there was a Method like "Appear Behind Text" or something similar.
How do I put in request for a Method like this be added to the next version as I feel it is a very useful feature for things like Watermarks.
 
As for adding more transparency I'm in a Catch-22 situation.  I have to add more transparency so I can see the text behind the watermark, but if I make it too transparent then the Watermark does not come out if the report is photocopied - maybe I can get away with a happy compromise.
 
Thanks Ingo for the reply.

Hi Chris!
 
That's heavy stuff!
There's no sample here.
You should read about layers and (optional) content groups in the reference.
You have to recreate the whole document for this (taking the layers away... drawing the watermark... then the layers back... puuuuh :)
Nearly the same and much easier it is to put a bit more transparency to the watermark ;-)
 
Cheers, Ingo
