How to export a image to act file
===

I'm trying to create a mini tool for my job. I'm using C# with Visual Studio 2010 to do that. Now I need to export an image to an act file.


Following here, http://msdn.microsoft.com/en-us/library/system.windows.media.imaging.bitmappalette.aspx

I wrote

    class Palette : List<Color>
    {
        public static Palette GetFromImage(String PathToImage)
        {
            //Load imgae
            BitmapImage image = new BitmapImage();
            image.BeginInit();
            image.UriSource = new Uri(PathToImage, UriKind.RelativeOrAbsolute);
            image.EndInit();

            //Load palette
            BitmapPalette BitmapPalette = new BitmapPalette(image, 256);
            

            //Convert it to list of Color
            Palette pal = new Palette();
            for (int i = 0; i < BitmapPalette.Colors.Count; i++)
            {
                pal.Add(Color.FromArgb(BitmapPalette.Colors[i].R, BitmapPalette.Colors[i].G, BitmapPalette.Colors[i].B));
            }
            //Return the palette has been creatted
            return pal;
        }


This code has effected, but the order of all colors in the result did not same as the order of all colors when I export by photoshop. So, when I write all colors to a act file, the act file is not correct.

Anybody can help me.

Many thank
