Export Presentation to XAML Format

In the world of software development, it’s essential to have tools that can simplify complex tasks. Aspose.Slides for .NET is one such tool that enables you to work with PowerPoint presentations programmatically. In this step-by-step tutorial, we’ll explore how to export a presentation to XAML format using Aspose.Slides for .NET.

Introduction to Aspose.Slides for .NET

Before we dive into the tutorial, let’s briefly introduce Aspose.Slides for .NET. It’s a powerful library that allows developers to create, modify, convert, and manage PowerPoint presentations without requiring Microsoft PowerPoint itself. With Aspose.Slides for .NET, you can automate various tasks related to PowerPoint presentations, making your development process more efficient.

Prerequisites

To follow along with this tutorial, you’ll need the following:

1. Aspose.Slides for .NET: Ensure that you have the Aspose.Slides for .NET library installed and ready to use in your .NET project.

2. Source Presentation: Have a PowerPoint presentation (PPTX) that you want to export to XAML format. Make sure you know the path to this presentation.

3. Output Directory: Choose a directory where you want to save the generated XAML files.

Step 1: Set up Your Project

In this first step, we’ll set up our project and make sure we have all the necessary components ready. Ensure that you’ve added a reference to the Aspose.Slides for .NET library in your project.

string dataDir = "Your Document Directory";
string outPath = "Your Output Directory";
// Path to source presentation
string presentationFileName = Path.Combine(dataDir, "XamlEtalon.pptx");

Replace "Your Document Directory" with the path to the directory containing your source PowerPoint presentation. Also, specify the output directory where the generated XAML files will be saved.

Step 2: Export Presentation to XAML

Now, let’s proceed to export the PowerPoint presentation to XAML format. We’ll use Aspose.Slides for .NET to achieve this.

using (Presentation pres = new Presentation(presentationFileName))
{
    // Create conversion options
    XamlOptions xamlOptions = new XamlOptions();
    xamlOptions.ExportHiddenSlides = true;

    // Define your own output-saving service
    NewXamlSaver newXamlSaver = new NewXamlSaver();
    xamlOptions.OutputSaver = newXamlSaver;

    // Convert slides
    pres.Save(xamlOptions);

    // Save XAML files to an output directory
    foreach (var pair in newXamlSaver.Results)
    {
        File.AppendAllText(Path.Combine(outPath, pair.Key), pair.Value);
    }
}

In this code snippet, we load the source presentation, create XAML conversion options, and define a custom output-saving service using NewXamlSaver. We then save the XAML files to the specified output directory.

Step 3: Custom XAML Saver Class

To implement the custom XAML saver, we’ll create a class named NewXamlSaver that implements the IXamlOutputSaver interface.

class NewXamlSaver : IXamlOutputSaver
{
    private Dictionary<string, string> m_result = new Dictionary<string, string>();

    public Dictionary<string, string> Results
    {
        get { return m_result; }
    }

    public void Save(string path, byte[] data)
    {
        string name = Path.GetFileName(path);
        Results[name] = Encoding.UTF8.GetString(data);
    }
}

This class will handle the saving of XAML files to the output directory.
