The properties of the System.Drawing.Imaging.ImageFormat class indicate image formats such as bitmap (ImageFormat.Bmp), enhanced metafile (ImageFormat.Emf), and icon (ImageFormat.Icon). For example, you can use the properties of the System.Drawing.Imaging.ImageFormat class to specify an image format when saving an image using the System.Drawing.Image.Save(string, ImageFormat) method. You can compare two image formats by using the ImageFormat.Equals(object) method.
