How to implement new look in osModule

[StefanNovakMP]

Hi,

I am interested in implementing this style of OpenStreetMap: https://github.com/Zverik/leaflet-grayscale
But I am not sure how to do it.
It is impossible to do it by the module administration.
Would you be so kind as to guide me on how to do it?

Thank you very much in advance.

Stefan

Basically, I think you're going to have to modify the osModule code, which is written in PHP.

I believe you want to edit line 235 of helper.php. The change might look like this:

$js .= "var baselayer".$id." = new L.TileLayer.grayscale('".$baselayerURL."', {".$baselayerSettings.$nowarp."attribution: '<a href="https://www.openstreetmap.org/copyright\" target="_blank">© OpenStreetMap contributors'});\n";

Note the reference you provided (https://github.com/Zverik/leaflet-grayscale) also suggest adding this option fadeAnimation: false

If you're not a coder, then you may want to find/hire someone who can do this customization work for you.
