Extract images to files

Here are the steps to extract images to files:

  • Instantiate Parser object for the initial document;
  • Call GetImages method and obtain collection of PageImageArea objects;
  • Check if collection isn’t null (images extraction is supported for the document);
  • Iterate through the collection and save image contents to the file.

The following example shows how to save images to files:

// Create an instance of Parser class
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");
    // 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);
