Implementation Guide

Feature: Conversion of EMLX File to PNG Format

This feature allows you to convert an EMLX file into a series of PNG images. Each step below will guide you through the process.

Step 1: Define Output File Path Template

First, set up your output directory and define how each page’s PNG image will be named:

string outputFileTemplate = Path.Combine(outputDirectory, "converted-page-{0}.png");

Step 2: Create a Function for Page Streams

Create a function to provide a stream for each converted page. This ensures that each PNG is saved correctly:

Func<SavePageContext, Stream> getPageStream = savePageContext => 
    new FileStream(string.Format(outputFileTemplate, savePageContext.Page), FileMode.Create);

Step 3: Initialize the Converter

With your EMLX file path and output setup ready, initialize the Converter object:

using (Converter converter = new Converter(Path.Combine(documentDirectory, "sample.emlx")))
{
    // Conversion process will be performed here
}

Step 4: Set Conversion Options for PNG Format

Specify that you want to convert your document into the PNG format using ImageConvertOptions:

ImageConvertOptions options = new ImageConvertOptions { Format = GroupDocs.Conversion.FileTypes.ImageFileType.Png };

Step 5: Perform the Conversion

Finally, execute the conversion process:

converter.Convert(getPageStream, options);

Troubleshooting Tips

  • File Path Errors: Ensure your file paths are correctly specified.
  • Permissions Issues: Verify that your application has read/write permissions for the directories used.

Practical Applications

  1. Document Management Systems: Automate email archiving by converting EMLX files into PNG images for easier viewing and storage.
  2. Legal Documentation: Convert sensitive emails into a non-editable format for secure sharing and record-keeping.
  3. Data Migration: Seamlessly transfer email data to other platforms that support image formats.

Performance Considerations

Optimizing performance is key when working with large files:

  • Batch Processing: Handle multiple conversions in batches to manage memory usage effectively.
  • Memory Management: Dispose of streams and objects properly to free up resources promptly.
