Hi, I want use Python to call halcon API via c/c++, do you have some advise for me?

Hi, thanks for your attention

I try to use ctype, I made a C funciton which return Hobject* as the output, while another function use Hobject* as input, and I make the dll for the functions.
When I use python to call the functions by ctype, I just can not get the right result, I want to get the wisth of the image ,but I always get '1' as output

Thanks a lot!
