Icons are not embedded in uMap sources, you will have to add them manually. So you can choose which icons you want to use.
You can use either PNG, JPG or SVG files. SVG files are recommanded.
When using SVG, it's recommanded to use icons without color. UMap will switch to white colors
automatically according to the marker background color.
Example of icons libraries you may want to use:
- [Maki Icons](https://labs.mapbox.com/maki-icons/) (icon set made for map designers)
- [Osmic Icons](https://gitlab.com/gmgeo/osmic)
- [SJJB Icons](http://www.sjjb.co.uk/mapicons/contactsheet)
- [Remix](https://remixicon.com/)

### Import icons automatically
To import icons on your uMap server, you will need to use command `umap import_pictograms`
To import icons on your uMap server, you will need to use command `umap import_pictograms`.
Note, you can get help with `umap import_pictograms -h`
Note: you can get help with `umap import_pictograms -h`
In this example, we will import Maki icons.
Basic usage:
First, we download icons from main site. Inside the downloaded archive, we keep only the icons folder that contains svg files. Place this folder on your server.
umap import_pictograms --attribution "Maki Icons by Mapbox" path/to/icons/directory/
Go inside icons folder and remove tiny icons: `rm *-11.svg`
### Categories
Now, we will use imagemagick to convert svg to png.
`for file in *.svg; do convert -background none $file ${file%15.svg}24.png; done`
To have white icons use:
`for file in *.svg; do convert -background none -fuzz 100% -fill white -opaque black $file ${file%15.svg}24.png; done`
Notes:
- you may also want to resize image with option `-resize 24x`
- this solution is not optimal, generated png are blurry.
This will convert the svg to png and rename them from `*-15.svg` to `*-24.png`
Now we will import icons. Note: icons names must end with `-24.png`
`umap import_pictograms --attribution "Maki Icons by Mapbox" icons`
Done. Icons are imported.
uMap can render icons grouped into categories. When using the import script, any
subfolder will be used as category.
