	using Gif.Components;//引用库Gif.Components.dll
	private string gif(string filename)
	 {
	 string gifname = string.Empty;
	 Image imgGif = Image.FromFile(filename );
	//先把gif拆开
	 FrameDimension ImgFrmDim = new FrameDimension(imgGif.FrameDimensionsList[0]);
	 int nFrameCount = imgGif.GetFrameCount(ImgFrmDim);
	 for (int i = 0; i < nFrameCount; i++)
	 {
	 imgGif.SelectActiveFrame(ImgFrmDim, i);
	 imgGif.Save(string.Format(@"d:\Frame{0}.jpg", i), ImageFormat.Jpeg);
	//将拆开的图片放大二倍
	 Bitmap bmp = new Bitmap(string.Format(@"d:\Frame{0}.jpg", i));
	 int w = bmp.Width * 2;
	 int h = bmp.Height * 2;
	 Bitmap b = new Bitmap(w, h);
	 Graphics g = Graphics.FromImage(b); // 插值算法的质量
	 g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;
	 g.DrawImage(bmp, new Rectangle(0, 0, w, h), new Rectangle(0, 0, bmp.Width, bmp.Height), GraphicsUnit.Pixel);
	 g.Dispose();
	 b.Save(string.Format(@"d:\Frame11{0}.jpg", i));
	 gifname += string.Format(@"d:\Frame11{0}.jpg", i) + ",";
	 }
	 return hgif(gifname);
	 }
	 private string hgif(string gifname)
	 {
	//再把gif合在一起
	 String[] imageFilePaths = gifname.TrimEnd(',').Split(',');
	 String outputFilePath = "D:\\test.gif";
	 AnimatedGifEncoder e = new AnimatedGifEncoder();
	 e.Start(outputFilePath);
	 e.SetDelay(200); // 延迟间隔
	 e.SetRepeat(0); //-1:不循环,0:总是循环 播放
	 for (int i = 0, count = imageFilePaths.Length; i < count; i++)
	 {
	 e.AddFrame(Image.FromFile(imageFilePaths[i]));
	 }
	 e.Finish();
	 return outputFilePath;
	 }
