Extract images from Emails Leave feedback

To extract images from emails GetImages method is used. By default images are extracted with its original format. With using ImageOptions class it is possible to extract images from emails as bmp, gif, jpeg, png and webp formats.

Warning

GetImages  method returns null value if image extraction isn’t supported for the document. For example, image extraction isn’t supported for TXT files. Therefore, for TXT file GetImages method returns null. If an email has no images, GetImages method returns an empty collection.

Here are the steps to extract images from an email to PNG-files:

• Instantiate Parser object for the initial email;
• Call GetImages method and obtain the collection of image objects;
• Iterate through the collection and save image contents to the file.

The following example demonstrates how to extract images from an email:

// Create an instance of Parser class
using (Parser parser = new Parser(filePath))
{
    // Extract images from the email
    IEnumerable<PageImageArea> images = parser.GetImages();
 
    // Create the options to save images in PNG format
    ImageOptions options = new ImageOptions(ImageFormat.Png);
 
    int imageNumber = 0;
    // Iterate over images
    foreach (PageImageArea image in images)
    {
        // Save the image to the png file
        image.Save(imageNumber.ToString() + ".png", options);
        imageNumber++;
    }
}
