public Bitmap Thumbnail { get; set; }

Public Property Thumbnail As Bitmap

Field Value

Each slide in a presentation includes a thumbnail that is displayed in the application's Slides Window. The thumbnail is automatically captured when the slide is created using the CaptureSlide()()() method on Presentation. You can use this property to get the thumbnail as a System.Drawing.Bitmap, or replace the thumbnail with your own image.

Note that when you change the property of a slide, such as its Viewpoint, Basemap, etc, the slide's thumbnail will not be updated automatically. The thumbnail is only captured automatically when creating a new slide with CaptureSlide()()().
