If you like me, enjoy photos of the Earth, you may also appreciate the ability to set a near real-time photo of it as your desktop wallpaper. It’s actually only delayed for up to 10 minutes!
You can choose between different resolutions which are referred to as quality. You can choose between quality
20. The application doesn’t come with a manual and the flag
--help doesn’t say anything about the quality options.
I tried them all and this is what I ended up with when about 90% of the Earth was visible:
|Quality||Resolution (pixels)||File size|
|4||2200 x 2200||5.83 MB|
|8||4400 x 4400||21.8 MB|
|16||8800 x 8800||79 MB|
|20||11000 x 11000||126 MB|
Be aware that the quality
20 eats a lot of memory when it processes the image! It used about 650 MiB of RAM for me. With quality
4 it only used about 40 MiB of RAM.
The recommended (or at least the easiest) way of installing it is via the Python package manager called
$ pip install --user himawaripy
If you don’t have
pip you need to install it. On systems like Gentoo and Arch Linux the package is called
python-pip, while on Debian and Debian based systems it’s called
The default usage is:
$ himawaripy -l <quality> --auto-offset
--auto-offset determines the timezone automatically. You can manually specify the UTC offset in hours yourself with the flag
-o, --offfset <-12 to +10>.
They only specify some common desktop environments as compatible, but it just fell back to
feh for me who doesn’t use a desktop environment.
If you only want to download the image and not set is as a wallpaper you can add the flag
$ himawaripy -l <quality> --dont-change
This is handy if you want to use the image for something else or just want to set it as a wallpaper yourself like I do.
How I use it
By default some of the Earth was hidden behind my panel. I didn’t liked it so I wrote a little script that adds a black border to the image and then sets that image as the wallpaper.
#!/bin/bash dir="$HOME/.cache/himawaripy" himawaripy -l 4 --auto-offset --dont-change convert -border 64x64 -bordercolor black $dir/himawari*.png $dir/output.png feh --bg-max $dir/output.png
I then added a cronjob that runs every 60 minutes to refresh the image:
*/60 * * * * $HOME/Scripts/space_wallpaper.sh
