How to enable the pylon_camera auto white image balance?

edit

Hello guys,

I'm using the ROS pylon_camera package with a Basler acA4600-10uc and after taking some frames I notice that the image quality isn't the same as the PyloViewerApp (Pylo API Viewer), because the PylonViewer has a function named Automatic Image Adjustment, that basically changes the brightness parameters and also the auto white balance feature. I'd like to know to enable the auto white image balance function.

The difference between the figures can be visualized here: https://github.com/magazino/pylon_cam...
