. This method is very suitable for server applications where
multiple clients request specific frames of a JPEG 2000 file. Instead of
decompressing and then recompressing the frames this method copies only
the needed frame data, saving the data to a new JPEG 2000 file.
Target Platforms: Microsoft .NET Framework 2.0, Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
