To accomplish this task:
Create a PdfDocumentProcessor instance and load the required PDF document using the overloaded PdfDocumentProcessor.LoadDocument method.
To export a page to a bitmap image, call the PdfDocumentProcessor.CreateBitmap method using the page number and the largestEdgeLength parameter measured in pixels. The latter parameter determines the output image height for pages in the portrait orientation and width - for landscape pages.
To export a page to a multi-page tiff image, call one of the PdfDocumentProcessor.CreateTiff overloaded methods using, for example, the file path where the converted image will be located, the largestEdgeLength parameter measured in pixels and page numbers.
