Free tool or library to convert Tiff files to pdf in .Net

Does any one know of a free tool or library to convert multi page tiffs to pdf in Asp.Net 1.1?

From stackoverflow

• Persist software's ASPPDFlib.dll might be of your help. http://www.asppdf.com/download.html

  Daud : It's not free. Neither are many other great products.

• Apparently there's no free tool for this.

  lothar : Of course the is! ImageMagick (http://www.imagemagick.org/script/index.php)

• Look into PDF Creator http://www.pdfforge.org/products/pdfcreator

  I know you can script it, but I don't know if you can do anything with it via ASP.NET. Either way it couldn't hurt to look.

• I've had to do this in asp.net before (actually JPG to PDF but close enough...) I use ImageMagick and shell out to it. I know its not native c# code, but its free and it works brilliantly. Just run a command line like this:

  cmd /c convert "c:\blah\original.tiff" "c:\blah\destination.pdf"

  The reason i use the 'cmd /c' is that without it, i have problems with System.Diagnostics.Process.Start messing up the arguments.

• Use ImageMagick.

  convert screenshot.tiff screenshot.pdf
  

• how about PDFSharp, or iTextSharp? I usually search sf.net first when looking for a free library.
