SLIDER Wallpaper

A command-line tool to download images from the RAMMB/CIRA SLIDER website and set them as your desktop wallpaper.

The tool will attempt to find a currently sunlit location, download the full-disk image from SLIDER, crop the zone into a separate (smaller) image and set it as your desktop wallpaper.

Currently supports downloading images from the following satellites:

• GOES-18
• GOES-19
• Himawari-9
• Meteosat-12

Uses the awesome wasm-vips image library to merge/crop the downloaded images.

SLIDER is the Satellite Loop Interactive Data Explorer in Real-time.

Caution

This tool will download ~180mb of data every time a new full image is available. This can end up using quite a lot of bandwidth if ran too often!

Inspiration

This tool was inspired by Downlink and SLIDER-cli.

This is not an official product of NWS, NOAA, RAMMB, or CIRA. This is not officially related to the SLIDER product.

• Fix deno compile to produce native executables
• Support other image formats (PNG, currently some images end up too big to work as backgrounds (I think?))
