I have trouble rendering a PDF with QuickPDF Library. My PDF contains some sort of "watermark", which is displayed ok with Adobe or Foxit Reader, but when rendered with Quick PDF, only currupted parts of this watermark are visible in the output.

Original PDF: https://od.lk/f/ODJfMzQ1ODQ2ODlf

This is how it should look like:


And this is how Quick PDF Library (v16.12) renders this PDF:



The watermark in the page's center is almost invisible. What can I do to get Quick PDF render this file correctly?

Hi Jan,

first you should try to use...
CombineContentStreams and
NormalizePage
...after the load and before rendering this could be an effect already.

Cheers and welcome here,
Ingo

Cheers,
Ingo

Hi Ingo,

thanks for the welcome, and of course, for the tips.

I just tried CombineContentStream and NormalizePage, but unfortunately no change to the output...

In my apps it looks similar to your sample here.
I think the problem is more how this watermark is made.
This here is a user-user-forum - so further help you should get on the official support page of Debenu/Foxit.
Please add a sample and complete description of your issue (try "report a bug" or "technical question"):

Did you find a solution for this? I'm having the same issue. I have a process running on Linux. It renders page text just fine, but none of the graphical content renders. Mine aren't even watermarks.

I can't be certain, but I suspect the issue concerns the PDF layers. When I ran the PDF through a compressor, the individual pages could then be extracted intact, with graphics.

UPDATE: I've given up on this under Linux and instead am calling ghostscript to extract PNG pages from the PDF. This is faster than my previous efforts using QuickPDF.
