Create animated GIF images using C#.

Sample Image - NGif.gif


Because .NET Framework can't create animated GIF images, NGif provides a way to create GIF animations in the .NET framework. It can create an animated GIF from several images and extract images from an animated GIF.

Using the code

/* create Gif */
//you should replace filepath
String [] imageFilePaths = new String[]{"c:\\01.png","c:\\02.png","c:\\03.png"}; 
String outputFilePath = "c:\\test.gif";
AnimatedGifEncoder e = new AnimatedGifEncoder();
e.Start( outputFilePath );
//-1:no repeat,0:always repeat
for (int i = 0, count = imageFilePaths.Length; i < count; i++ ) 
 e.AddFrame( Image.FromFile( imageFilePaths[i] ) );
/* extract Gif */
string outputPath = "c:\\";
GifDecoder gifDecoder = new GifDecoder();
gifDecoder.Read( "c:\\test.gif" );
for ( int i = 0, count = gifDecoder.GetFrameCount(); i < count; i++ ) 
 Image frame = gifDecoder.GetFrame( i ); // frame i
 frame.Save( outputPath + Guid.NewGuid().ToString() 
                       + ".png", ImageFormat.Png );
