I am publishing data trough different publisher, mainly with visualization_msgs::Marker and nav_msgs::GridCells objects. I get a visualization in my RVIZ window and what I want to do is to save this visualization into an image of the size I want.
Do you know if there is a plug-in who can do that ? Or if there is some other way to do that ?
I don't want to do a screen shot because i would like the size of my image to be bigger than the actual definition of my screen.
