一、 说明

本文主要讲VS中如何实现图片的合成！

二、 代码

    private void InitializeComponent()
        {
            this.button1 = new System.Windows.Forms.Button();
            this.button2 = new System.Windows.Forms.Button();

                pictureBox3.Image = bt;
            }
        }

三、 效果图

先选择第一张图片
如图所示：

然后选择第二张图片
如图所示：

然后点击合成图片
如图所示：

四、 总结
逆水行舟，不进则退！
