[Gtk-sharp-list] Getting frames from a GIF animation

[Doug Blank]

I couldn't figure out how to access the data through Gtk#, so I got
the data through System.Drawing:

public static List loadPictures (string filename)
{
   List list = new List();
   System.Drawing.Bitmap image =
(System.Drawing.Bitmap)System.Drawing.Bitmap.FromFile(filename);
   System.Drawing.Imaging.FrameDimension dimension = new
          System.Drawing.Imaging.FrameDimension(image.FrameDimensionsList[0]);
   int frame_count = image.GetFrameCount(dimension);
   for (int i=0; i < frame_count; i++) {
      image.SelectActiveFrame(dimension, i);
      list.append( new Graphics.Picture(image));
   }
   return list;
}
