Implementation Guide

Now, let’s explore how you can implement various document conversion features using GroupDocs.Viewer .NET.

Render PST/OST Document to HTML

Overview

Converting PST/OST files to HTML allows for easy sharing and viewing of email archives in web browsers. This feature is perfect for creating web-based presentations or reports from your Outlook data.

Step 1: Set Up Output Directory

string outputDirectory = Path.Combine("YOUR_OUTPUT_DIRECTORY", "RenderToHTML");
string pageFilePathFormat = Path.Combine(outputDirectory, "PST_result.html");

// Ensure the output directory exists.
Directory.CreateDirectory(outputDirectory);

Step 2: Configure HTML View Options

Configure options to embed resources directly into the HTML for better portability:

using (Viewer viewer = new Viewer("YOUR_DOCUMENT_DIRECTORY\\SAMPLE_PST"))
{
    HtmlViewOptions options = HtmlViewOptions.ForEmbeddedResources(pageFilePathFormat);

    // Render the document to HTML format using specified options.
    viewer.View(options);
}

Explanation:

  • HtmlViewOptions.ForEmbeddedResources: Embeds all resources (like images) into the HTML, making it self-contained.

Troubleshooting Tips

  • Ensure paths are correctly specified and accessible.
  • Check file permissions in your output directory if encountering access issues.

Render PST/OST Document to JPG

Overview

Creating JPG images from PST/OST files is useful for generating previews or thumbnails of email archives.

Step 1: Set Up Output Directory

string outputDirectory = Path.Combine("YOUR_OUTPUT_DIRECTORY", "RenderToJPG");
string pageFilePathFormat = Path.Combine(outputDirectory, "PST_result_{0}.jpg");

// Ensure the output directory exists.
Directory.CreateDirectory(outputDirectory);

Step 2: Configure JPG View Options

Use a placeholder for dynamic file naming:

using (Viewer viewer = new Viewer("YOUR_DOCUMENT_DIRECTORY\\SAMPLE_PST"))
{
    JpgViewOptions options = new JpgViewOptions(pageFilePathFormat);

    // Render the document to JPG format using specified options.
    viewer.View(options);
}

Explanation:

  • JpgViewOptions: Allows you to specify output paths dynamically with placeholders.

Troubleshooting Tips

  • Verify that your system supports image generation and has sufficient memory for processing large files.

Render PST/OST Document to PNG

Overview

PNG format is ideal for high-quality, lossless images of email content. This feature allows detailed snapshots of your Outlook archives.

Step 1: Set Up Output Directory

string outputDirectory = Path.Combine("YOUR_OUTPUT_DIRECTORY", "RenderToPNG");
string pageFilePathFormat = Path.Combine(outputDirectory, "PST_result_{0}.png");

// Ensure the output directory exists.
Directory.CreateDirectory(outputDirectory);

Step 2: Configure PNG View Options

Configure options with placeholders for file names:

using (Viewer viewer = new Viewer("YOUR_DOCUMENT_DIRECTORY\\SAMPLE_PST"))
{
    PngViewOptions options = new PngViewOptions(pageFilePathFormat);

    // Render the document to PNG format using specified options.
    viewer.View(options);
}

Explanation:

  • PngViewOptions: Similar to JPG, but optimized for lossless image output.

Troubleshooting Tips

  • For large PST/OST files, monitor memory usage during rendering.

Render PST/OST Document to PDF

Overview

Converting PST/OST files into a single PDF document is useful for archiving or sharing email data in a universally accessible format.

Step 1: Set Up Output Directory

string outputDirectory = Path.Combine("YOUR_OUTPUT_DIRECTORY", "RenderToPDF");
string pageFilePathFormat = Path.Combine(outputDirectory, "PST_result.pdf");

// Ensure the output directory exists.
Directory.CreateDirectory(outputDirectory);

Step 2: Configure PDF View Options

Configure options for a single document output:

using (Viewer viewer = new Viewer("YOUR_DOCUMENT_DIRECTORY\\SAMPLE_PST"))
{
    PdfViewOptions options = new PdfViewOptions(pageFilePathFormat);

    // Render the document to PDF format using specified options.
    viewer.View(options);
}

Explanation:

  • PdfViewOptions: Used for rendering documents into a consolidated PDF file.

Troubleshooting Tips

  • Check if your document includes unsupported elements that might affect PDF conversion.
