.NET PDF to TIFF tutorial shows how to convert .pdf file to .tif / .tiff image using PDF Renderer SDK. Use C# or Visual Basic .NET source code below for PDF conversion.

C#

	// Create an instance of Bytescout.PDFRenderer.RasterRenderer object  to convert pdf to tiff
 	RasterRenderer renderer = new RasterRenderer();
 	renderer.RegistrationName = "demo";
 	renderer.RegistrationKey = "demo";

 	// Load PDF document into renderer to perform pdf to tif rendering
 	renderer.LoadDocumentFromFile("multipage.pdf");

                       // pdf to tiff conversion
                       renderer.RenderPageRangeToMultipageTIFFFile (0, renderer.GetPageCount()-1, TIFFCompression.LZW, "multipage.tiff");

 	// Open the first output file in default image viewer.
 	System.Diagnostics.Process.Start("multipage.tif");

VB.NET

 ' Create an instance of Bytescout.PDFRenderer.RasterRenderer object to convert PDF to TIFF
 Dim renderer As New RasterRenderer()
 renderer.RegistrationName = "demo"
 renderer.RegistrationKey = "demo"

 ' Load PDF document.
       renderer.LoadDocumentFromFile("multipage.pdf")

       ' define PDF page to start from for PDF to tif conversion
       Dim StartPageIndex As Integer = 0
       ' define page to end on
       Dim EndPageIndex As Integer = renderer.GetPageCount() - 1

       ' Render PDF to TIFF image file (with multiple TIF pages)
       renderer.RenderPageRangeToMultipageTIFFFile(StartPageIndex, EndPageIndex, TIFFCompression.LZW, "multipage.tiff")

       ' Open the first output file in default image viewer.
       System.Diagnostics.Process.Start("multipage.tiff")
