Is it possible to export a PDF or image in RViz? I'd basically like to output the map created somehow.

Any ideas on how to achieve this?

rviz is a data visualizer that subscribes to published topics and help us visualize them. You therefore need some way to publish your image. You can write a script to do this or use tool like image_publisher.

If you want to capture a map there's a tool to do that called map_saver in the map server packages

Do you know of anything that could capture the map as well as markers?

If you're looking for images of the composite/overlay you see on the screen you can capture that via screencapture. If you want to replay it/interact you likely want to record the raw data and replay it to be able to interact with it during the playback.

I've just noticed the Save Image option in the RVizFile menu. Is this what you mean? The output from this is actually perfect but I'd need to be able to do it programmatically. Any idea how?
