Please advice how can I render the preview of the existing PDF file to a Bitmap so I can display it on my form?
Many thanks in advance.

iTexhSharp cannot render a PDF to an image, your best bet would be to have a look at GhostScript.
I have a c# wrapper for the GhostScript dll that that do this, email me at the address on my profile page and I will email it to you.

I want to perform OCR on png and pdf files.I am able to get Tesseract 3.0.2 .net wrapper work for png files but I can't find any class in it for PDf files.So, does it work for the pdf files.If not then please let me know any other open source library for scanning pdfs. My requirement is scanning diagrams in a pdf for specific circles, and creating hyperlinks for those circles.
No, it doesn't. You'll have to extract the images from the pdf first. This can be done using pdfimages pdfimages.exe -j your.pdf or gs as suggested by Zakk Diaz.

I am developing application wich produce a report with graph. I read about free C# libraries to create PDF but I can't see any completely FREE geenrator to use in application that I want to sell. Can you give me one?
Other problem is to generate a simple chart. What are the tools to create such a graph? I need to put it into pdf document after generating it.
Thx for help!
PDF reporting could be done using nfop. I know someone who has done PDF with that, but I do not know more.
Regarding the charting: you could use Microsoft Chart controls, render to an image and include an image in the PDF.
Using WKHtmlToPDF to generate PDFs for my company's web-based mapping service.
Essentially, I take a template HTML file, inject an image into a div, save the HTML to disk and use WKHtmlToPDF to render to PDF.
Now, on most templates it works a treat. On one particular one though, where the image should be (int the pdf) is a grey area. HOWEVER, if I right click on the grey area, and select "Save Image As...", the saved image is correct.
Linked are the created PDF and the HTML on which it is based. Help required most urgently, and hints appreciated.
Zip File Containing HTML and PDF
I was having an issue where a particular image was not being printed to the PDF. Other images on the same page were. The src of the missing image is from a CDN, but had no extension, i.e. src="\\path/to/image?param". Using the aforementioned -n switch (disable Javascript), the image shows up in the resulting PDF. Thanks Jordaan.
Don't know WHY this worked, but adding the "--disable-smart-shrinking" option, and/or removing the "-n"(Disable Javascript) option, fixed it.
