WPF PDF Viewer control supports viewing, reviewing, and printing PDF files in WPF applications. The PDF Viewer also provides a way to convert PDF files into images in a format such as .jpg, .png, and .tiff in C# and VB.NET using the ExportAsImage API. You can use the images in your application to create thumbnails or cover page for a document, and more. Convert a page of the PDF file into TIFF imageYou can refer to the following steps for performing the same: Step 1: Include the following namespace in the MainWindow.xaml.cs file. C# using Syncfusion.Windows.PdfViewer; using System.IO; using System.Windows; using System.Windows.Media.Imaging; Step 2: Using the following code snippet, a PDF page can be exported as TIFF image. C# /// <summary>
/// Exports the PDF pages as Tiff Images.
/// </summary>
/// <param name="fileName">The PDF file name</param>
private void ExportPDFtoTiff(string fileName)
{
PdfDocumentView pdfViewer = new PdfDocumentView();
//Load the input PDF file
pdfViewer.Load(fileName);
//Export the first page as image .
BitmapSource image = pdfViewer.ExportAsImage(0);
if (image != null)
{
//Initialize the new Tiff bitmap encoder
TiffBitmapEncoder encoder = new TiffBitmapEncoder();
//Set the compression to zip to reduce the file size.
encoder.Compression = TiffCompressOption.Zip;
//Create the bitmap frame using the bitmap source and add it to the encoder.
encoder.Frames.Add(BitmapFrame.Create(image));
//Create the file stream for the output in the desired image format.
using (FileStream stream = new FileStream("Image" + ".Tiff", FileMode.Create))
{
//Save the stream, so that the image will be generated in the output location.
encoder.Save(stream);
}
}
}
Convert a specific range of pages of the PDF file into TIFF imagesYou can refer to the following steps for performing the same: Step 1: Include the following namespace in the MainWindow.xaml.cs file. C# using Syncfusion.Windows.PdfViewer; using System.Windows.Media.Imaging; using System.IO; Step 2: Using the following code snippet, the specific range of pages of a PDF file can be exported as TIFF images. C# /// <summary>
/// Exports the PDF pages as Tiff Images.
/// </summary>
/// <param name="fileName">The PDF file name</param>
private void ExportPDFtoTiff(string fileName)
{
PdfDocumentView pdfViewer = new PdfDocumentView();
//Load the input PDF file
pdfViewer.Load(fileName);
//Export the images From the input PDF file at the page range of 0 to 1 .
BitmapSource[] image = pdfViewer.ExportAsImage(0, pdfViewer.PageCount - 1);
if (image != null)
{
for (int i = 0; i < image.Length; i++)
{
//Initialize the new Tiff bitmap encoder
TiffBitmapEncoder encoder = new TiffBitmapEncoder();
//Set the compression to zip to reduce the file size.
encoder.Compression = TiffCompressOption.Zip;
//Create the bitmap frame using the bitmap source and add it to the encoder.
encoder.Frames.Add(BitmapFrame.Create(image[i]));
//Create the file stream for the output in the desired image format.
using (FileStream stream = new FileStream("Image_" + i.ToString() + ".Tiff", FileMode.Create))
{
//Save the stream, so that the image will be generated in the output location.
encoder.Save(stream);
}
}
}
