  • Get the thumbnail image of the referenced slide on a specified scale.
  • Save the thumbnail image in any desired image format.


 //Instantiate a Presentation class that represents the presentation file

using (Presentation pres = new Presentation("Slides Test Presentation.pptx"))


  //Access the first slide

  ISlide sld = pres.Slides[0];

  //Create a full scale image

  Bitmap bmp = sld.GetThumbnail(1f, 1f);
