I was using the saveScreenshot from the visualizer to save a PNG image
from my pointcloud.
But now, I am running my program in a remote server from ssh and I can't
simply save images like I did. This is because the method saveScreenshot needs a GUI to generate the image.
I tried to use the savePNGFile, but my cloud is unorganized .
Does someone had the same issue before? Any ideas how to solve the problem?
