图像处理系统设计.docx

1、图像处理系统设计图像处理系统设计一、设计目的随着社会的发展，数码相机以及相关产品的使用率大大增加，使得电子相片越来越普及。由于使用者的经验不是很足，导致很多相片都达不到很好的效果，这迫切需要一款图像处理软件，为此我开发设计了图像处理系统，服务大众。二、设计思路1.文件：打开，保存，另存为；2.图像：垂直翻转、水平翻转、翻转90度；3.滤镜：浮雕、黑白、反色、锐化、反色、棕褐色；三、流程图四、界面设计五、关键代码1.浮雕处理private void btnfudiao_Click(object sender, EventArgs e) /以浮雕效果显示图像 if (pictureBox1.Ima
