Deprecated getImageArray() call?

[scottnortman]

Hi,

I followed the example as shown for the visual_tracker.py example for another project I am working on, and my python ROS2 node always crashes when I call camera.getImageArray()

Instead, I was able to get the following code to work:

    def get_image_from_camera( self ):
        '''
        Get an image from the camera.  Per webots documentation, the method
        getImage returns a byte string and it needs to be converted.

        '''
        img = self.camera.getImage()
        imageRGBA = np.fromstring( img, dtype='uint8').reshape((self.camera.getHeight(), self.camera.getWidth(), 4))

        return imageRGBA

Not sure if this is due to any recent webots changes as I am running the latest 2021b, but I wanted to let you know.
