Create animated GIF images using C#.

Sample Image - NGif.gif

Introduction

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 );
e.SetDelay(500);
//-1:no repeat,0:always repeat
e.SetRepeat(0);
for (int i = 0, count = imageFilePaths.Length; i < count; i++ ) 
{
 e.AddFrame( Image.FromFile( imageFilePaths[i] ) );
}
e.Finish();
/* 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 );
}

GeneralTransparency Not Working Pin

I've tried settign a value for the transparency but no matter what I do it doesn't work. I noticed that the FindClosest function called in Save() was beign called before the Analyze function. I updated the code so that FindClosest now returns what looks like an accurate index as far as I can tell but when I look at th eGif in IE then the transparency is not showing (excuse the 'pun') and in a Gif editor the transparency is not set.

Has anyone else tried using the transparency in this? I really want to avoid sitting down and reading the enitre Gif Spec to understand this!

Thanks in advance

Jim
