Implementation Guide

Rendering Archive Files with Specified Filenames

Overview

This feature allows you to render archive files into PDF format while specifying the output filename.

Step 1: Set Up Viewer and Options

Begin by setting up the Viewer object and configuring the PDF rendering options:

using System;
using System.IO;
using GroupDocs.Viewer;
using GroupDocs.Viewer.Options;

class Program
{
    static void Main(string[] args)
    {
        string outputDirectory = "YOUR_DOCUMENT_DIRECTORY";
        
        using (Viewer viewer = new Viewer("path/to/your/archive.zip"))
        {
            PdfViewOptions options = new PdfViewOptions(Path.Combine(outputDirectory, "custom-filename.pdf"));

            // Render the archive to PDF with specified filename
            viewer.View(options);
        }
    }
}
Step 2: Explanation of Parameters and Configuration
  • Viewer: Initializes with the path to your archive file.
  • PdfViewOptions: Accepts a string parameter for specifying the output PDF’s filename.

Troubleshooting Tips

  • Ensure the output directory exists before running the code.
  • Verify that you have write permissions for the specified path.

Practical Applications

Use Cases and Integration Possibilities

  1. Automated Report Generation: Convert archived reports into PDFs with predefined filenames to maintain consistency in documentation.
  2. Invoice Archiving: Automatically generate PDF invoices from ZIP files, specifying a filename based on invoice details.
  3. Email Attachments: Use this feature when integrating email clients that download attachments as archives.

Integration Possibilities

  • Integrate with .NET web applications for dynamic document rendering.
  • Combine with cloud storage APIs to fetch and render archived documents directly in the cloud.

Performance Considerations

Optimizing Performance

  • Resource Management: Ensure proper disposal of Viewer objects using using statements to prevent memory leaks.
  • Batch Processing: Process large batches of files asynchronously to optimize resource usage.

Best Practices for .NET Memory Management with GroupDocs.Viewer

  • Always release resources by disposing of the viewer object after operations.
  • Avoid loading large files into memory at once; use streaming where possible.

Conclusion

In this tutorial, we explored how to render archive files into PDFs with specified filenames using GroupDocs.Viewer for .NET. By following these steps, you can streamline your document management processes and ensure consistency in file naming conventions.
