How to get the specific perspective of mlab.view()?

I am trying to save hundreds of point cloud visualization figures，and I fixed the perspective of point clouds to make a continuous video by the following code:
`mlab.view(azimuth=a elevation=b, distance=c, roll=d)`
where "a,b,c,d" are the parameters. It is hard to adjust these parameters to get a suitable perspective. I know that we can use the mouse to drag the visual interface to find a suitable perspective, but is there any way to print out these parameters in the visual interface?

Very kind of your help.
