I’m in a hurry. Help. This is the OPEN CV’contour’ question.

I want to get the x,y coordinate values for’contour’.

Please tell me a way to get the x,y coordinates. Please.

int x =?  
int y =?

I know you are busy but that’s not how you format code - not `”` Button but please use `</>`.

Also this is not a customer support so I don’t think it’s good to emphasize “I’m in a hurry” ☹

I would delve into the references and examples that come with the library.  
The repository for this is on GitHub.

Again, please format your code first 🙂

For contour, I guess this gives you some information:
