# How to: Encode and Decode a GIF Image
The following examples show how to decode and encode a Graphics Interchange Format (GIF) image using the specific <xref:System.Windows.Media.Imaging.GifBitmapDecoder> and <xref:System.Windows.Media.Imaging.GifBitmapEncoder> objects.  
  
## Example  
 This example demonstrates how to decode a GIF image using a <xref:System.Windows.Media.Imaging.GifBitmapDecoder> from a <xref:System.IO.FileStream>.
