Dark Basemap

[ooosssay]

A dark basemap would be great to have as sometimes when I am mapping I would switch to mapnik then get flash banged by the white colors so I’d really appreciate having a dark basemap. The only thing I could find a dark mode Mapnik was by inserting css code in a Github issue but I don’t know if that’s possible in an app but at the same time I don’t fully understand what I’m talking about.

I implemented this in a branch, but haven’t merged it because I thought it needed more feedback. One minor nitpick is that white roads are now black, and other roads have new colors:

Yeah, the roads look weird but also the buildings and icons may be a little to bright.

That's using the CSS trick, which isn't the best approach when we have the full power of CoreImage available.

I pushed the branch to https://github.com/bryceco/GoMap/tree/dark-mode-basemap if anyone wants to play with it. The color adjustment is done in https://github.com/bryceco/GoMap/blob/dark-mode-basemap/src/Shared/Utility/DarkModeImage.swift

This is just reducing the brightness (-40%) of the image:

Yeah at that brightness the icons should be good
