Does any one know of a free tool or library to convert multi page tiffs to pdf in Asp.Net 1.1?
Persist software's ASPPDFlib.dll might be of your help. http://www.asppdf.com/download.html
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.
how about PDFSharp, or iTextSharp? I usually search sf.net first when looking for a free library.
