2. Implement the ability to extract the image in a different format

   Description

   This feature allows to extract images to files.

   Public API changes

   • Added GetImageStream(ImageOptions) method to GroupDocs.Parser.Data.PageImageArea class

   Usage

   GetImageStream(ImageOptions) method is used to extract the image in a different format.

   ImageOptions class is used to define the image format into which the image is converted. The following image formats are supported:

   • Bmp
   • Gif
   • Jpeg
   • Png
   • WebP

   Example:

   // 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");
           return;
       }
       // Create the options to save images in PNG format
       ImageOptions options = new ImageOptions(ImageFormat.Png);
   
       // Iterate over images
       foreach (PageImageArea image in images)
       {
           using (Stream stream = image.GetImageStream(options))
           {
               // add a logic to work with the stream
           }
       }

   // 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");
           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);
           imageNumber++;
       }
   }
