Ok so , I found this cool code and I can't use it. You see ... We have to input an Image which I can do it 开发者_开发百科but we also need to Input Colors which I dont know how to do it...

public static Bitmap Colorize(Bitmap Image, Color[] Colors)
{
    if (Colors.Length < 256)
       return null;
    Bitmap TempBitmap = new Bitmap(Image.Width, Image.Height);
    for (int x = 0; x < Image.Width; ++x)
    {
        for (int y = 0; y < Image.Height; ++y)
        {
           int ColorUsing = Image.GetPixel(x, y).R;
            TempBitmap.SetPixel(x, y, Colors[ColorUsing]);
        }
    }
    return TempBitmap;
}


You need to pass in an array of Color objects, as follows:

        Bitmap bitmapToColorize = new Bitmap(@"C:\bitmap.bmp");
        Color[] colors = new Color[2];
        colors[0] = Color.Blue;
        colors[1] = Color.Green;

        Colorize(bitmapToColorize, colors);

Of course, looking at the method, it looks like you need to fill the Color array with at least 256 colors.

I would recommend you read up on arrays.
