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.

Anybody can please help me with creating a PDF with Watermark using NReco in C#.NET?
I want to dynamically add image as Watermark while generating PDF from html to PDF concept. I am not able to find any code for this available easily.
I'm trying to discover if there is a way, a library, or tool today that would help me to detect the shapes programmatically on a PDF file or an Illustrator File. I have seen some libraries such as Shapely or Pyclipper but haven't been able to use a PDF or AI file as an input for the library to process.
I know this is possible using image processing libraries but converting the file to an image would lose its layers and properties. Any alternatives?
I have a pdf file which includes graphs, not in image format. Is there any way to process pdf file using content streams and fetch graphs out of it
We have pdf documents (source: camera or scanner) that we want to convert to jpeg.
We use LEADTOOLS and PDF-TOOLS(in two separate programs) to convert these pdf files to jpeg files.
Both these tools use the default DPI of 150 irrespective of the DPI of the source pdf file.
We would rather like this value to be taken from the source pdf file.
For example: Adobe Acrobat software recognizes the source pdf file DPI and uses the same to create the jpeg file.
Is there some way we could achieve the same using the LEADTOOLS and PDF-TOOLS by determining the DPI of the source pdf file?
This feature was added to v19 of LEADTOOLS a few months ago. You can now extract images from PDF pages while preserving their original pixel dimensions using the following members of the Leadtools.Pdf.PDFDocument class:
ParseDocumentStructure method.
Images property.
DecodeImage method.
Furthermore, if the image is stretched inside the PDF page, you can detect that by examining its display size in the PDF page using the Leadtools.Pdf.PDFObject.Bounds property.
There's a dedicated demo for the PDFDocument class and related objects installed with LEADTOOLS 19 in these folders:
Examples\DotNet\CS\PDFDocumentDemo
Examples\DotNet\VB\PDFDocumentDemo
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
