For this we can leverage the RasterCodecs class. This class offers a number of overloads for loading and saving files.


The following code snippet demonstrates how the load and save method overloads would be use to create multipage TIFFs from PDF and individual TIFFs from PDF.

using (RasterCodecs codecs = new RasterCodecs())
    //load the original PDF
    codecs.Options.Load.AllPages = true;
    using(RasterImage image = codecs.Load(@"C:\Users\Public\Documents\LEADTOOLS Images\Leadtools.pdf"))
        //save as multipage tiff
        codecs.Save(image, @"output path.tif", RasterImageFormat.Tif, 0, 1, -1, 1, CodecsSavePageMode.Overwrite);

        //save each page as individual tiff
        for (int i = 1; i <= image.PageCount; i++)
            codecs.Save(image, @"output path" + i + ".tif", RasterImageFormat.Tif, 0, i, i, 1, CodecsSavePageMode.Overwrite);

Another option is to use the RasterImage Class to create multipage images in memory. The RasterImage object can hold multiple pages with different sizes. The AddPage, AddPages, InsertPage and InsertPages methods allows adding new pages to an existing RasterImage.
