These icons were created by the Graphic Designer Ashley Jager. She released these icons in a beautiful Adobe Illustrator file.
See the full description of this project on the author github page https://github.com/manifestinteractive/weather-underground-icons
I wrote a bash script to convert these nice icons from svg to png files, to be used in the xfce4-weather-plugin.
- Run the make-xfce-weather.sh script from the console
- Select the desired theme
- Copy the 3 generated folders and the theme.info file
- Right click on the xfce weather plugin on the taskbar and select Properties
- Click on the icon near Icon theme: the icons folder will open.
- Create a new folder and name it Underground. Paste the folders and the theme file inside this new folder.
- Close and re-open the xfce weather plugin Properties window. In the Icon theme dropdown list the Underground theme will be present.
Have fun!
