I want to use opencv library and Nana library at the same time. How to convert OpenCV image data into Nana:: image? 我想同时使用opencv 库和nana库， opencv 的图像数据转换为 nana::image的解决办法？

无法拷贝到image中，但是可以用nana::paint::pixel_buffer::put 然后再paste到graphics上

可以改写image相关的类，增加一个内存拷贝的image类型，我在nana中增加cairo二维绘图给弄出来了，我记得好像还要改写一个image的上层文件就可以了，增加一个内存的图像接口，同理，opencv的mat也可以这么干https://git.soulrace.top/gui/nana_dev1.8/src/branch/develop-1.8/source/paint/detail/image_Mem.hpp
