    {
    
    
        public MainForm()
        {

        private void btnLoadImage_Click(object sender, EventArgs e)
        {
    
    
            // 加载图像到 PictureBox
            string imagePath = "image.jpg"; // 图像的路径
            Image image = Image.FromFile(imagePath);
            pictureBox.Image = image;
        }

        private void btnClearImage_Click(object sender, EventArgs e)
        {
