Multiple .tif files to a single .pdf file

I am looking for an example that will take a bunch of .tif files and output a single .pdf file.
I am not looking to use any windows forms.  I have the list of files and the output filename.

Thanks.

You can simply use the LEADTOOLS Load and the Save methods
without using any user interfaces. Also, to save PDF files you need to download
and install LEADTOOLS PDF plug-in. For more information about the LEADTOOLS PDF plug-in, please see this page:
http://www.leadtools.com/SDK/Raster/Raster-Addon-PDF.htm

However the detailed information regarding these methods depends on the following two points:
1. Your preferred programming interface, LEADTOOLS has (DLLs API, C++ Class Library, .NET classes, ActiveX and COM objects)
2. Your preferred development language such as (VB, VC++, VB.NET or C#, etc…)

Here is a C# code snippet that loads four separate TIF files and then saves them out as a single PDF with the v15 .NET libraries:

RasterImage img;

img = codecs.Load("1.tif", 0, CodecsLoadByteOrder.Bgr, 1, 1);
img.AddPage(codecs.Load("2.tif", 0, CodecsLoadByteOrder.Bgr, 1, 1));
img.AddPage(codecs.Load("3.tif", 0, CodecsLoadByteOrder.Bgr, 1, 1));
img.AddPage(codecs.Load("4.tif", 0, CodecsLoadByteOrder.Bgr, 1, 1));

codecs.Save(img, "combined.pdf", RasterImageFormat.RasPdf, 24, 1, 4, 1, CodecsSavePageMode.Overwrite);
