Basic Initialization and Setup

Here’s how you can initialize GroupDocs.Conversion:

using System;
using GroupDocs.Conversion;

class Program
{
    static void Main()
    {
        // Initialize license if available
        // License lic = new License();
        // lic.SetLicense("path/to/license/file.lic");

        Console.WriteLine("GroupDocs.Conversion initialized.");
    }
}

Now, let’s move on to the core functionality—converting EML files to PDF with a timezone offset.

Implementation Guide

Feature 1: Convert Email Document to PDF with Timezone Offset

This feature allows you to convert an email document into a PDF while applying a specific timezone offset. Here’s how it works:

Step 1: Define Load Options for the Email Document

Create a function that sets load options, including the desired timezone offset.

using System;
using GroupDocs.Conversion.Options.Load;

Func<LoadContext, LoadOptions> getLoadOptions = loadContext => new EmailLoadOptions
{
    ConvertOwned = false,
    TimeZoneOffset = TimeSpan.FromHours(5) // Apply a +5 hours timezone offset
};

Explanation:

  • ConvertOwned: Set to false to avoid altering the original document.
  • TimeZoneOffset: Adjusts the email’s timestamp by 5 hours forward.

Step 2: Convert EML to PDF

Initialize the Converter object and perform the conversion.

using System;
using System.IO;
using GroupDocs.Conversion;

string outputFolder = Path.Combine("YOUR_OUTPUT_DIRECTORY");
string outputFile = Path.Combine(outputFolder, "converted.pdf");

using (Converter converter = new Converter(Path.Combine("YOUR_DOCUMENT_DIRECTORY", "SAMPLE_EML"), getLoadOptions))
{
    PdfConvertOptions options = new PdfConvertOptions();
    converter.Convert(outputFile, options);
}

Explanation:

  • The Converter object takes the EML file and load options as parameters.
  • PdfConvertOptions: Configures conversion settings for PDF output.

Feature 2: Configure Output Directory

Set up a directory to save your converted documents:

using System.IO;

string outputFolder = Path.Combine("YOUR_OUTPUT_DIRECTORY");
if (!Directory.Exists(outputFolder))
{
    Directory.CreateDirectory(outputFolder);
}

Explanation:

  • Ensures the specified directory exists, creating it if necessary.

Practical Applications

  1. Email Archiving: Convert and store emails as PDFs for long-term archiving.
  2. Legal Documentation: Use converted PDFs in legal processes where email evidence is required.
  3. Business Reporting: Integrate into reporting systems to generate PDF summaries from email threads.
  4. Compliance Management: Ensure compliance by maintaining a consistent document format with timezone accuracy.
  5. Cross-Platform Sharing: Easily share emails as universally accessible PDF files.

Performance Considerations

For optimal performance, consider these tips:

  • Optimize Resource Usage: Manage memory efficiently by disposing of objects promptly.
  • Batch Processing: Convert multiple documents in batches to reduce overhead.
  • Configuration Tuning: Adjust conversion settings based on document size and complexity.
