Arguments in launch files

edit

Hello Leo,

when I open launch file on the link below there are a lot of arguments. Are they all required to be set?

NO, Leo In a real sense, if you are having a use case that required more things or you want some different output rather the normal one at that time only you need to set arguments.

For example, if I don't use Fisheye can I delete all arguments for it: width, height, fps, frame_ids, etc. I tried deleting it and it works but I don't know if I'm allowed to do that.

I think you should not don't delete any code or program from a real-sense driver and if you are not using you can disable it by arguments, but never delete code from the intel realsense package it can affect your camera performance.

  <arg name="enable_fisheye"      default="false"/>
  <arg name="enable_fisheye1"     default="false"/>
  <arg name="enable_fisheye2"     default="false"/>

By default, it is already in a false state. That means anyways it is not going to execute.

There are many arguments in this launch file, luckily there are defaults set for them. This probably means that simply not setting them will work. I don't know the ins and outs of the application or launch file, so you I can't tell you it with certainty. For more details on the <arg> tag see the launch docson ros.org.
