Quick to convert PDF file to multipage TIFF image using C#


Converting PDF to TIFF image using XDoc.PDF for .NET is straightforward. Use the PDFDocument class to convert the document to multiplage TIFF image directly. Below are the steps and sample C# code.

  • Create a new PDFDocument object and load an existing PDF file to it.
  • Use PDFDocument.ConvertToDocument() method to convert PDF to TIFF image



            String inputFilePath = @"W:\Projects\Test-Files\file1.pdf";
            String outputFilePath = @"W:\Projects\Test-Output\RasterEdge.com\pdf-convert-pdf-to-tiff-quick.tif";

            //  Open file
            PDFDocument doc = new PDFDocument(inputFilePath);
            //  Convert whole document to TIFF file
            doc.ConvertToDocument(DocumentType.TIFF, outputFilePath);




PDF to TIIF Convert Image Options


Using XDoc.PDF for .NET, you can easily convert multi-pages PDF file into tiff. The following Tiff document settings supported in class "ImageOutputOption":


  1. Color: Output image is Monochrome, Gray, Color.

  2. Compression: defines the compression scheme used on the image data in the output TIFF file. Valid values:
    Uncompressed: No compression used.
    PackBits: Using a simple byte-oriented run-length scheme.
    CCITT1D: Using CCITT Group 3 1-Dimensional Modified Huffman run-length encoding.
    Group3Fax: Using CCITT T.4 bi-level encoding.
    Group4Fax: Using CCITT T.6 bi-level encoding.
    LZW: Using Lempel-Ziv & Welch (LZW) algorithm.
    JPEG: Using JPEG baseline based on the Discrete Cosine Transform (DCT).

  3. Resolution: Set image resolution value in the TIFF image file.

  4. Zoom: Set PDF page zoom value to use more pixels to render the page.



Below are the steps and C# sample source code to convert Adobe PDF file to multipage TIFF image programmatically using C#.

  1. Set converted TIFF image options, including Image Color, Image Compression, Image Resolution and PDF page zoom value.
  2. Create a new PDFDocument object from a PDF file
  3. Call method PDFDocument.ConvertToDocument() to convert PDF to TIFF image file with options applied.



            String inputFilePath = @"W:\Projects\Test-Files\file1.pdf";
            String outputFilePath = @"W:\Projects\Test-Output\RasterEdge.com\pdf-convert-pdf-to-tiff.tif";

            ImageOutputOption options = new ImageOutputOption();
            //  Output image is color.
            options.Color = ColorType.Color;
            //  Use LZW compression in TIFF file.
            options.Compression = ImageCompress.LZW;
            //  Set resolution to 300 dpi for each page.
            options.Resolution = 300;
            //  Set zoom value to 2F. Use more pixels to render the page.
            options.Zoom = 2;

            //  Open file
            PDFDocument doc = new PDFDocument(inputFilePath);
            //  Convert whole document to TIFF file
            doc.ConvertToDocument(DocumentType.TIFF, outputFilePath, options);
