I have a system where users can upload PDF documents. Rather than displaying the link to these PDFs as a title link, or a PDF icon link, I would like it to be a thumbnail of the first page of the PDF document.
How can I get a thumbnail image of the first (or any specified) page of a PDF document, using ASP.NET 3.5?
Here is a free component to display PDF thumbnails in asp.net: http://www.tallcomponents.com/pdfthumbnail-versions.aspx
GhostScript is another option.
There are no built in PDF capabilities in the BCL.
You will need to use a PDF library that allows you to output images. Use it to render the first page as a thumbnail.
Here is one article on code project to do this (using acrobat and COM interop), here a thread on MSDN forums .

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 need to open a PDF in the client.
The PDF its generated in my Controller (i have no problem with that) and i need to show that PDF inside a layout (not a window).

You could show the pdf in a SmartGWT component using an IFrame.
See this sample and this forum.
Is there any API in js or .net or any other free tool through which page coordinates can be obtained in a pdf? Basically, I have a pdf file which contains images so I have read the coordinates on click inside the pdf document.
*coordinates here refer to .pdf page coordinates and not pixel coordinates, however I used itext library but couldn't figure out the solution.
In order to read the coordinates of an image when it's clicked on in the PDF, you're going to need to use a PDF viewer that is capable of running scripts. Unfortunately, there are only a few of those and they all implement only a portion of the Acrobat JavaScript API but the Acrobat JavaScript API can't tell you anything about images or their location so it's doubtful that any of the others would. However, you could create a plug-in to Reader and/or Acrobat and add that functionality but then all of your users would need to install both Acrobat/Reader and your plug-in.
Assuming I understood the user experience you are looking for, I don't think it's possible without a customized viewer.
I have a PDF file on the sharepoint server, I wanted to access that PDF file and generate a thumbnail image on the fly. Is any of the Javascript frameworks supports this feature to implement..
Can anyone help me out to convert the PDF file into an thumbnail image?
There is a couple of products can view PDF files online and generate a thumbnail image, but I recommended this tool document viewer that can preview some types of files by thumbnail, also view this PDF file online.http://www.boostsolutions.com/sharepoint-document-viewer.html
I want to make PDF viewer, I tried many open source libraries, but it failed, just as jpedal and PDF renderer the last one open blank pages, I don't want to use google docs to view the PDF, Is there an easy way to display PDF on my application?
