I'm implementing a PDF editor on UWP using PDFium as the base library. I cannot seem to find any proper way of adding/creating watermarks on a document.
I went through the PDFium source and spec documents but didn't find anything useful.
I tried to analyze some PDF documents with watermarks but it is unclear how they are created and couldn't find a common mapping too.
Could someone please help me understand how watermarks are added to PDF documents?
Any help is much appreciated. Thanks
I have a pdf which is layered when trying to read the PDF file it is just reading the header of the PDF and footer of the PDF. I am looking for a library which can read the layered PDF.
Please guide.
We have a need to take a single PDF file, break it into separate page thumbnails, and based on user input, put together selected pages into a new PDF document.
Can someone show a quick example of how to take a single PDF document and generate a thumbnail preview of each page using either MigraDoc or PDFsharp?
Those who read FAQ lists will know that neither PDFsharp nor MigraDoc can render PDF files.
To create thumbnails from PDF pages you have to render them.
You'll need a different library to create thumbnails.

I have an asp.net (c#) web application.
I joined together some pdf files on serverside with itextsharp.
The result pdf is too large (>1M) to be downloaded in our environment.
I checked fonts list in Adobe Reader and Verdana font embedded 10 times. It could be a problem. I don't know why? I use iTextSharp PDFCopy for merging.
If I capture the file by fiddler and than print it out by bullzip pdf printer the size become the half (500KB)!!!
I can't figure out what bullzip pdf printer does to reduce the size???
All the joined pdfs are mosty text only a couple of small images.
Interesting when I try to copy/paste text from the original pdf I can, but I can't from the bullzip printed version (i get only rectangles when paste). That is no problem by the way because I don't need to edit or search by text, I only need to print it from the browser.
I need some .net library to do the same with the pdf before I send it to the browser.
Can anyone help me?
I got issues in rendering a couple of images and texts in PDF in Telerik PDF viewer - according to Telerik's documentation it seems those texts/images formats are incompatible.
Are there ways to convert existing images in a PDF and replace it back to the PDF so to make the file compatible to the Telerik PDF viewer?
Many thanks
