HSmartWindowControl 滚轮缩放 交互式绘制ROI 可修改 存储

一直想达到这个效果,奈何智商简单;今天来做一下记录;

个人习惯 Winform 新建以后删除xxx.designer.cs再双击Form1.cs设计器;就会在该 文件下

自动生成InitializeComponent() 且可 由设计器生成的所有winform界面程序则会出现在InitializeComponent()里面;

这样的好处很多,所有设计器的操作都可以以单一文件程序的方式呈现在面前

想要一个这样的功能:

可以自适应图片缩放在不同图像宽高比和窗口宽高比 的 情况下 保证图像完整显示并居中

缩放的同时绘制ROI ROI可以记录 位置下次修改 可以存储ROI位置 存储 ROI抠的图

算了 虽然这个不完善: 但最近流行一句话 一个粗糙的开始就是最好的开始.

算了算了 上程序.
