copied!<p>I ended up modifying <a href="http://www.codeproject.com/KB/GDI-plus/NGif.aspx" rel="noreferrer">http://www.codeproject.com/KB/GDI-plus/NGif.aspx</a> code to get what I needed and it worked! :)</p> <p>for the gif source file handling I added this method:</p> <pre><code> private bool AddGifFrames(Image image) { // implementation var fd = new FrameDimension(image.FrameDimensionsList[0]); int frameCount = image.GetFrameCount(fd); var frames = new List<Tuple<int, Image>>(); if (frameCount > 1) { frames = new List<Tuple<int, Image>>(); //0x5100 is the property id of the GIF frame's durations //this property does not exist when frameCount <= 1 byte[] times = image.GetPropertyItem(0x5100).Value; for (int i = 0; i < frameCount; i++) { //selects GIF frame based on FrameDimension and frameIndex image.SelectActiveFrame(fd, i); //length in milliseconds of display duration int length = BitConverter.ToInt32(times, 4 * i); //save currect image frame as new bitmap frames.Add(new Tuple<int, Image>(length, new Bitmap(image))); } } // Not animated foreach (var frame in frames) { HandleFrame(frame.Item2, frame.Item1); } return true; } </code></pre> <p>and as for the custom delays I've modified this method:</p> <pre><code> protected void WriteGraphicCtrlExt(int? delay) { Fs.WriteByte(0x21); // extension introducer Fs.WriteByte(0xf9); // GCE label Fs.WriteByte(4); // data block size int transp, disp; if (Transparent == Color.Empty) { transp = 0; disp = 0; // dispose = no action } else { transp = 1; disp = 2; // force clear if using transparent color } if (Dispose >= 0) { disp = Dispose & 7; // user override } disp <<= 2; // packed fields Fs.WriteByte(Convert.ToByte(0 | // 1:3 reserved disp | // 4:6 disposal 0 | // 7 user input - 0 = none transp)); // 8 transparency flag WriteShort(delay ?? Delay); // delay x 1/100 sec Fs.WriteByte(Convert.ToByte(TransIndex)); // transparent color index Fs.WriteByte(0); // block terminator } </code></pre> <p>to sum it up - this code can add a gif as a frame by splitting it to frames and adding them, and it can also add custom delays.</p>
