This is an updated to the "NGif, animated GIF Encoder for .NET" article on the The Code Project web site. NGif is a set of C# classes which can create animated GIF images. Microsoft's native GDI library does not support the creation of animated GIFs.
My update supports returning the animated GIF as a MemoryStream object instead of a file. This is helpful on webservers where saving temporary files are not allowed.
