In my CFMX on my Windows laptop, I have escaped all of the backslashes so the paths look like this: c:\\\\somepath\\\\file.pdf That should be c: (two backslashes) somepath (two backslashes) file.pdf. Can you try that? Otherwise... maybe send me the PDF and the PNG and I can try it here to see if there is a difference? @Tim, I just found an interesting difference between the code I posted and the way it displayed.

I create a PDF using CFDocument and save it. Then I call the UDF. I actually changed the UDF so it properly var'd the variables since I have it in a CFC. I see the original PDF, as well as the PDF the UDF creates (yes, a different name). Both have the exact same size, which is why I wonder if it is really working for me. When I open the new PDF, I dont see any image. In my call, I specify zindex of 1, x of 100 and y of 100. Then I tried y of -100 thinking that was the problem. Then I thought maybe the image path I am passing in isnt valid, but an image does exist at that location. My call (I renamed the UDF to insertImageOntoPDF: <code> </code> Do you see anything wrong?

Passing in 100 just behaves like 1 in my example. I do the same thing as you, it requires three steps: <ol> <li>Use CFDOCUMENT and write the results to disk</li> <li>Use the UDF above to insert the watermark</li> <li>Retrieve/CFCONTENT the new PDF back to the user</li> </ol> I don't believe you can use the same filename for in and out, if that's what you're doing, due to file lock issues. Also, keep in mind that the x/y are specified from the lower left hand corner so it's possible, depending on what values you use, that your watermark might be off the screen. @Tim, the zIndex value is either 0 (under) or 1 (over).

When I try it out, it does indeed create a new PDF, but I cant seem to get the watermark to display. The size of the old and new PDFs are the same, which makes me wonder if it is really working. I am calling insertWatermarkPDF passing in 100 as the zindex trying to force it to the top (to see if it shows up) but I still dont see it. The HTML in my document doesnt have any background color specified. Where am I going wrong? Tim I found your code trying to add a watermark to a CFDOCUMENT-generated PDF.

I just tried this on a 110 page report and processing time was cut by about 10s (out of 140) but the load on the machine was 50% of what it was when there were 110 HTTP requests. In a few limited tests using the watermark UDF (and not including the image in the original report), I cut processing time from about 140s to 55s. The constant resampling of the PNG I'm using is a real killer and this single watermark step seems to get around that. I think I'll write another post once I solve this and have it back in production. Dan, you’re 100% right.
