export data in bag file using rqt_bag

edit

Hi all,

I am trying to extract sensor and images data that saved in a bag file and save them into csv and image (png?) respectively. For old rxbag, it can be easily done by following: Select the range of the data we want, Plot the sensor data, right click the plot and save into csv. Show the image and there is a button to save the images.

However, I cannot find those option in the rqt_bag.

Thanks very much
