Question

I was making a 2d map editor for my square tile platformer game, when I realized I could really use an image editor with its abilities to repaint adjacent pixels and many mo

 public Color[][] getBitmapColorMatrix(string filePath)
    {
        Bitmap bmp = new Bitmap(filePath);
        Color[][] matrix;
        int height = bmp.Height;
        int width = bmp.Width;
        if (height > width)
        {
            matrix = new Color[bmp.Width][];
            for (int i = 0; i <= bmp.Width - 1; i++)
            {
                matrix[i] = new Color[bmp.Height];
                for (int j = 0; j < bmp.Height - 1; j++)
                {
                    matrix[i][j] = bmp.GetPixel(i, j);
                }
            }
        }
        else
        {
            matrix = new Color[bmp.Height][];
            for (int i = 0; i <= bmp.Height - 1; i++)
            {
                matrix[i] = new Color[bmp.Width];
