How to convert PDF to images using C# and ImageMagick?

Question

I would like to convert a PDF file to .GIF using C# and magicknet.dll. I have added the reference to the MagickNet Dll to my project.

MagickNet.Magick.Init();
MagickNet.Image img = new MagickNet.Image("d:/aa.pdf");
img.Write("d:/bb.gif");
MagickNet.Magick.Term();
img.Dispose();

System.Runtime.InteropServices.SEHException was unhandled by user code
  Message="External component has thrown an exception."

I think PdfSharp has a way to render PDFs to images. Check their documentation at www.pdfsharp.com.

Answer 2

ImageMagick requires GhostScript to Interpret PDF files. If you want you can call the GhostScript dll directly (contact me via my profile, I will send you a c# wrapper)

Alternatively you can use the GhostScript command line or a commercial 3rd party component, eg the PDF libraries from Tall Components.
