I would be open to a pull requests to add a button to the image_view plugin that saves the currently displayed image: https://github.com/ros-visualization/rqt_common_plugins/blob/groovy-devel/rqt_bag_plugins/src/rqt_bag_plugins/image_view.py

is that what you are thinking?

well, I am a beginner to ROS, and, I don't understand what I am supposed to
do with the github code. I have a bag file from which I need to extract
stereo images

If you have a specific problem you need solved I think a better solution is to ask your question over at answers.ros.org. Writing a simple node to dump the topic to a file would probably get you there quicker anyway.

I still think this enhancement is a good idea and if anyone out there has time to work on it I would be willing to review the pull request.

I have created a PR to extend rqt_image_view to export images to files: ros-visualization/rqt_common_plugins#326

While that does not solve this specific use case I thought it was a useful first step.

Not sure if this was saikrishna-1996's original idea but it would be nice to export all images published to a camera topic (raw or compressed) so that they can be used for training nueral networks.
