Initial Description
This technical tip shows how to convert PDF pages to TIFF image inside .NET Applications.  The TiffDevice class allows you to convert PDF pages to TIFF images. This class provides a method named Process which allows you to convert all the pages in a PDF file to a single TIFF image. To convert a particular page in a PDF file to a TIFF image, use an overloaded version of the Process(..) method which takes a page number as an argument for conversion.
