我只想获取图像所选部分的高度和宽度.该矩形将具有可移动的角(我可以拖动它)以增加/减小其大小.下面的链接演示了我想开发的东西的演示[该链接演示了HTML中的相同问题，但我希望在VB.NET中实现].

我将其添加到基于表单的应用程序中.请帮忙.
我不知道该怎么做！因此，复制粘贴应用程序代码将非常有帮助.

I want to get height and width of an image''s selected portion only. That rectangle will have moveable corners (which I can drag around) to increase/decrease its size. The link below illustrates a demo of something I would like to develop [the link demonstrates same problem in HTML, but I want this in VB.NET].

I''ll add this in a form based application. Please help.
I''ve no idea how to do it ! So a copy paste application code will be really helpful
