轻松实现轮廓绘制功能的方法？ [英] Light easy way to implement contour drawing feature?

问题描述

我正在尝试实现绘制闭合轮廓的特征，该轮廓定义了我感兴趣的区域。我想用鼠标手动绘制一个包围图像中某个对象的轮廓。轮廓应该在最后关闭，像ImageJ那样。我想知道是否有任何工具，C ++中的第三方库可以帮助解决这个问题。我知道OpenCV可能是一个来源，但我正在努力实现简单易用的东西。那么反正这样做了吗？任何指针都很受欢迎。谢谢。 --Nick

I am trying to implement a feature of drawing closed contour that defines my region of interest. I would like to manually draw a contour that encloses some object in a image using my mouse. The contour should be closed at the end, something like ImageJ does. I am wondering if there is any tools, 3rd party libs in C++ can help with this. I know probably OpenCV can be a source, but I am trying to implement something light and easy. So is there anyway to do so? Any pointer is appreciated. Thanks. --Nick

推荐答案

我们曾经在VB2的图片框上使用PSET（像素集）命令。



我不知道这个命令是否仍然可以在一个图片框对象中使用，但它非常基本所以我认为它仍然存在。



据我所知使用的命令类似.....

We used to use PSET (pixel set) command on a picturebox in VB2.

I dont know if that command is still available in a picturebox object but its is pretty basic so I shuold assume its still there.

As far as i can remember the command used go something like.....

MyPictureBox1.Pset(X,Y,Color)

看看这个样本我做了什么

它不在C ++中，但它不应该太难以移植

Look at this sample i did

its not in C++ but it shouldn''t be too difficult to port
