How to change `png_level` parameter by yaml #151

Open hyunseok-yang opened 1 year ago

hyunseok-yang commented 1 year ago

I tried to set png_level for compressed topic like below.

But failed to set the value even though I can get the value through ros2 param get /camera/camera .aligned_depth_to_color.image_raw.png_level command.

/camera/camera:
  ros__parameters:
    .aligned_depth_to_color.image_raw.png_level: 1
    .color.image_raw.png_level: 1
    .depth.image_rect_raw.png_level: 1

I checked if this is really changed. comapred before applying yaml file with after applying it.

yg@YG-ROS:ws$ ros2 param get /camera/camera .aligned_depth_to_color.image_raw.png_level
Integer value is: 3
yg@YG-ROS:ws$ ros2 param get /camera/camera .aligned_depth_to_color.image_raw.png_level
Integer value is: 1

Hi @hyunseok-yang , you'll want to use the parameter name exactly as you see as listed upon running:

ros2 param list /camera/camera

assuming /camera/camera is your node. I tried setting the parameters using YAML, and it worked fine. I don't think the leading "." for your parameters should be there.

Was it really changed in here also?

It's humble version of node.

It looks the value for that paramter is still '3'.

ijnek commented 1 year ago

Can you set it using ros2 param set like below? I am able to set it on Humble. Change the node name and parameter name appropriately:

vscode@ijnek-ThinkPad:/png_level_ws$ ros2 param get /v4l2_camera image_raw.png_level 
Integer value is: 3
vscode@ijnek-ThinkPad:/png_level_ws$ ros2 param set /v4l2_camera image_raw.png_level 4
Set parameter successful
vscode@ijnek-ThinkPad:/png_level_ws$ ros2 param get /v4l2_camera image_raw.png_level 
Integer value is: 4

image_raw.png_level

I guess something is different.

yg@YG-ROS:ws$ ros2 param get /ns1/cam1 image_raw.png_level 
Parameter not set

@hyunseok-yang

It would really help if you shared what ROS distro you are using (foxy, galactic, humble, iron?)

And yes, if you look at #140

From your output:

I guess something is different.

yg@YG-ROS:ws$ ros2 param get /ns1/cam1 image_raw.png_level Parameter not set

Here are all I got for parameters

Clearly there is no parameter you are asking for in the list

# try with some that exists on the list
ros2 param get /ns1/cam1 color.image_raw.png_level

Judging from your output you have topic scoped parameters.

Which suggests ROS2 foxy or humble

  • ROS2 image_transport parameters undergone serious evolution

    • started scoped in node (e.g. camera.png_level)

    • moved to topic scope

    • e.g. camera.image_raw.png_level

    • or like camera.color.image_raw.png_level

    • moved to transport scope

    • e.g. camera.image_raw.compressed.png_level

    • or like camera.color.image_raw.compressed.png_level

  • and this will likely depend on which distro you are using

    • all previous parameter scopes were wrong in the sense that parameters of different things would clash

I'm using humble :)
