Convert PDF to EMF | C#

The EmfDevice class allows you to convert PDF pages to EMF images. This class provides a method named Process which allows you to convert a particular page of the PDF file to EMF image format.

Convert PDF Pages to EMF Images

Aspose.PDF for .NET allows you to convert all pages in a PDF file to images:

  1. Loop through all pages in the file.
  2. Convert each page individually:
    • Create an object of the Document class to load the PDF document.
    • Get the page you want to convert.
    • Call the Process method to convert the page to EMF.

The following code snippet shows you how to convert all PDF pages to EMF images with C#.

Convert single PDF page to EMF image

Aspose.PDF library allows you to convert a particular page to EMF format:

Pass the page index as an argument to the Process(..) method. The following code snippet shows the steps to convert the first page of PDF to EMF format.

public static void ConvertPDFtoEmfSinglePage()
{
    // Open document
    Document pdfDocument = new Document(_dataDir + "PageToEMF.pdf");

    using (FileStream imageStream = new FileStream(_dataDir + "image_out.emf", FileMode.Create))
    {
        // Create Resolution object
        Resolution resolution = new Resolution(300);
        // Create EMF device with specified attributes
        // Width, Height, Resolution
        EmfDevice emfDevice = new EmfDevice(500, 700, resolution);

        // Convert a particular page and save the image to stream
        emfDevice.Process(pdfDocument.Pages[1], imageStream);

        // Close stream
        imageStream.Close();
    }
