Resource Steam Font Source Example

If you’re working with documents in .NET and using Aspose.Words, managing font sources can be a crucial aspect of ensuring your documents look as expected. Aspose.Words offers a powerful way to handle fonts, including using resource streams. In this guide, we’ll walk through using a resource stream as a font source with Aspose.Words for .NET. Let’s dive in!

Prerequisites

Before we get started, make sure you have the following:

  • Basic Knowledge of C#: Familiarity with C# programming will help you follow along.
  • Aspose.Words for .NET Library: Download and install it from the download link.
  • Development Environment: A setup like Visual Studio to write and execute your code.
  • Sample Document: Have a sample document (e.g., Rendering.docx) ready to test the font settings.

Import Namespaces

To start working with Aspose.Words, you need to import the necessary namespaces into your project. This provides access to the classes and methods you’ll need.

using Aspose.Words;
using Aspose.Words.Fonts;
using System.IO;
using System.Reflection;

Step 1: Define the Document Directory

First, specify the directory where your document is stored. This is crucial for locating the document you want to process.

// Path to your document directory
string dataDir = "YOUR DOCUMENT DIRECTORY";

Step 2: Load the Document

Load your document into an Aspose.Words Document object. This allows you to manipulate the document programmatically.

Document doc = new Document(dataDir + "Rendering.docx");

Step 3: Configure Font Settings

Now, configure the font settings to use the system font source along with a custom resource stream font source.

FontSettings.DefaultInstance.SetFontsSources(new FontSourceBase[]
{
    new SystemFontSource(),
    new ResourceSteamFontSource()
});

Step 4: Implement the Resource Stream Font Source

Create a class that extends StreamFontSource to handle fonts from an embedded resource stream. This class will fetch the font data from the assembly’s resources.

internal class ResourceSteamFontSource : StreamFontSource
{
    public override Stream OpenFontDataStream()
    {
        return Assembly.GetExecutingAssembly().GetManifestResourceStream("resourceName");
    }
}

Step 5: Save the Document

Finally, save the document after applying the font settings. Save it in a format of your choice; here, we’ll save it as a PDF.

doc.Save(dataDir + "WorkingWithFonts.SetFontsFolders.pdf");

By following these steps, you’ve configured your application to use a resource stream as a font source, ensuring that the necessary fonts are embedded and available for your documents.

Conclusion

You’ve now mastered the process of using a resource stream as a font source with Aspose.Words for .NET. This technique will help you manage fonts more efficiently and ensure that your documents always look their best. Keep experimenting with different settings to fully leverage the power of Aspose.Words.
