  2. Convert EML to HTML by using Save method
  3. Load HTML by using Document class
  4. Save the document to JPEG format using Save method and set Jpeg as SaveFormat

Get Started with .NET File Format APIs

Install from command line as nuget install Aspose.Total or via Package Manager Console of Visual Studio with Install-Package Aspose.Total.

Alternatively, get the offline MSI installer or DLLs in a ZIP file from downloads .

MailMessage message = MailMessage.Load("sourceFile.eml");
// save EML as a HTML 
message.Save("HtmlOutput.html", SaveOptions.DefaultHtml);
// load HTML with an instance of Document
Document document = new Document("HtmlOutput.html");

By using MapiMessage class of Aspose.Email for .NET API, you can get sender and recipients information. For example, you can check for a specific sender email for the conversion by using SenderName property.

var outlookMessageFile = MapiMessage.FromFile("message.eml");
// check for SenderName 
if(outlookMessageFile.SenderName == "John"){
    //proceed with conversion process
}

Restrict JPEG Document Editing via .NET

While saving the document from EML to JPEG, you might need to protect your output document. Sometimes you may need to limit the ability to edit a document and only allow certain actions with it. This can be useful to prevent other people from editing sensitive and confidential information in your document. Aspose.Words for .NET API, enables you to control the way you restrict the content using the ProtectionType enumeration parameter. You can set your document to read-only by using the following lines of code.

Document document = new Document("HtmlOutput.html");
// apply document protection and set protection password
doc.Protect(ProtectionType.ReadOnly, "password");
// call save method while passing SaveFormat.Jpeg
document.Save("output.jpeg", SaveFormat.Jpeg);

JPEG What is JPEG File Format?

A JPEG is a type of image format that is saved using the method of lossy compression. The output image, as result of compression, is a trade-off between storage size and image quality. Users can adjust the compression level to achieve the desired quality level while at the same time reduce the storage size. Image quality is negligibly affected if 10:1 compression is applied to the image.  The higher the compression value, the higher the degradation in image quality.
