Aspose.Page for .NET provides a robust set of features for working with XPS files, enabling developers to seamlessly convert them to PDF format with various customization options.

Prerequisites

Before we embark on this conversion journey, make sure you have the following prerequisites in place:

  • Aspose.Page for .NET Library: Ensure that you have the Aspose.Page for .NET library installed in your development environment. You can download it from the Aspose.Page documentation.

  • Development Environment: Set up a .NET development environment with Visual Studio or any other compatible IDE.

  • XPS Document: Prepare the XPS document that you want to convert to PDF. This could be your sample XPS file stored in a designated directory.

Import Namespaces

Before diving into the code, let’s import the necessary namespaces to make the Aspose.Page for .NET functionalities accessible in our code:

using Aspose.Page.XPS;

Step 1: Initialize Document Directory

string dataDir = "Your Document Directory";

Replace “Your Document Directory” with the path to the directory containing your XPS document.

Step 2: Initialize PDF and XPS Streams

using (System.IO.Stream pdfStream = System.IO.File.Open(dataDir + "XPStoPDF_out.pdf", System.IO.FileMode.OpenOrCreate, System.IO.FileAccess.Write))
using (System.IO.Stream xpsStream = System.IO.File.Open(dataDir + "input.xps", System.IO.FileMode.Open))

Open streams for both the output PDF file and the input XPS file. Ensure you have the appropriate file paths set.

Step 3: Load XPS Document

XpsDocument document = new XpsDocument(xpsStream, new XpsLoadOptions());

Load the XPS document using the Aspose.Page for .NET library.

Step 4: Initialize PDF Save Options

PdfSaveOptions options = new PdfSaveOptions()
{
    JpegQualityLevel = 100,
    ImageCompression = PdfImageCompression.Jpeg,
    TextCompression = PdfTextCompression.Flate,
    PageNumbers = new int[] { 1, 2, 6 }
};

Set up the PDF save options, including parameters like JPEG quality level, image compression, text compression, and specific page numbers to include.

Step 5: Create PDF Rendering Device

PdfDevice device = new PdfDevice(pdfStream);

Create a rendering device for the PDF format using the Aspose.Page for .NET library.

Step 6: Save Document to PDF

document.Save(device, options);

Save the XPS document to PDF using the specified rendering device and options.
