Hello,

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.

Take a look at #q142351 and #q258251 - rviz_camera_stream should do what you want.

I didn't find any solution. What i am doing right now is just a screen shot but I use the option created by rviz for thaht to be easier. file -> Save image.

You're asking a lot of RVIZ to be fair. To achieve what you want it would have to create a new GL viewport of the resolution you're asking for and redraw the current scene into this custom viewport then save it to a file. You could potentially do it with a plugin but it's a lot of work.
