On pre-Windows Mobile 5.0 devices, because the image encoders are not available in the OS, NETCF V2 does not support saving bitmaps into Gif, Jpeg or Png formats; only the Bmp format is supported. A NotSupportedException is thrown when you call the method on Pocket PC 2003 devices. All four file formats are supported in Windows Mobile 5.0.
