RasterEdge C#.NET PDF to TIFF converting library control (XDoc.PDF) is a multifunctional PDF document converting tool,
which can perform high-fidelity PDF to TIFF conversion in an easy way. Using this .NET PDF to TIFF conversion control,
C# developers can render and convert PDF document to TIFF image file with no loss in original file quality.
Both single page and multi-page Tiff image files are acceptable.
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":
- Color: Output image is Monochrome, Gray, Color.
- 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).
- Resolution: Set image resolution value in the TIFF image file.
- 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#.
- Set converted TIFF image options, including Image Color, Image Compression, Image Resolution and PDF page zoom value.
- Create a new PDFDocument object from a PDF file
- 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);
