Change exposure and gain params

Hi:
I am using zed-ros-wrapper on ubuntu to record images from ZED2i,
I want to set exposure manully, so I changed params and set auto_exposure_gain to false in file common.yaml in /zed_wrapper/params accordingly
But it does not seem to work.
Am I doing it right, what should I do?
Thanks

Please provide more information. What are you seeing?

For example:
I set auto_exposure_gain false, set exposure to 1, and display images on rviz, hoping to see a darker image, but the brightness seems the same as before.

@zpf I just fixed the silly bug. You can pull the master branch, recompile and enjoy the working feature

thanks, this solved my problem.
