$ curl wttr.in/Amsterdam?m $ curl wttr.in/Amsterdam?m
## Supported formats
Wttr.in supports three output formats at the moment:
* ANSI for the terminal;
* HTML for the browser;
* PNG for the graphical viewers.
The ANSI and HTML formats are selected basing on the User-Agent string.
The PNG format can be forced by adding `.png` to the end of the query:
$ wget wttr.in/Paris.png
You can use all of the options with the PNG-format like in an URL, but you have
to separate them with `_` instead of `?` and `&`:
$ wget wttr.in/Paris_0tqp_lang=fr.png
Special useful options for the PNG format:
* `t` for transparency (`transparency=150`);
* transparency=0..255 for a custom transparency level.
Transparency is a useful feature when the weather PNG's are used to
add to add weather data to the pictures:
$ convert 1.jpg <( curl wttr.in/Oymyakon_tqp0.png ) -geometry +50+50 -composite 2.jpg
Here:
* `1.jpg` - sorce file;
* `2.jpg` - target file;
* Oymyakon - name of the location;
* tqp0 - options (recommended).
