See this code find in internet if can help.


The Code - An Animated GIF Class

Let's apply all of the concepts into one easy-to-use C# class:

public class GifImage
     private Image gifImage;
     private FrameDimension dimension;
     private int frameCount;
     private int currentFrame = -1;
     private bool reverse;
     private int step = 1;

public GifImage(string path) { gifImage = Image.FromFile(path); //initialize dimension = new FrameDimension(gifImage.FrameDimensionsList[0]); //gets the GUID frameCount = gifImage.GetFrameCount(dimension); //total frames in the animation }

public bool ReverseAtEnd //whether the gif should play backwards when it reaches the end { get { return reverse; } set { reverse = value; } }

public Image GetNextFrame() {
currentFrame += step;

//if the animation reaches a boundary... if (currentFrame >= frameCount || currentFrame < 1) { if (reverse) { step *= -1; //...reverse the count currentFrame += step; //apply it } else currentFrame = 0; //...or start over } return GetFrame(currentFrame); }

public Image GetFrame(int index) { gifImage.SelectActiveFrame(dimension, index); //find the frame return (Image)gifImage.Clone(); //return a copy of it } }
