Extract all Images and Save them in PNG Format

using (Parser parser = new Parser(Constants.SampleZip))
{
    // extract images from document
    IEnumerable<PageImageArea> images = parser.GetImages();
    // check if images extraction is supported
    if (images == null)
    {
        Console.WriteLine("Page images extraction isn't supported");
        return;
    }
    // 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);
