After a futile attempt to write a tool that would extract those icons automatically and make them usable for Text Mapper, I did the work by hand. Look at the example below… Beautiful! And since this is SVG, you can quickly generate your first map and later you can keep working on it using Inkscape.
To regenerate the map above, visit Text Mapper and use the following “map”:
The Gnomeyland example map uses the tiles from the library. Here’s what you would need to generate just the lower part of the map:
include https://alexschroeder.ch/contrib/gnomeyland.txt 0005-0806 trail 0105 dark-green fir-forest "to the caves" 0106 dark-green fir-forest 0205 green fir-forest 0206 green fir-forest 0305 green firs 0306 soil keep "The Keep" 0405 light-soil 0406 light-soil 0505 light-grey mountains 0506 light-green forest-hill 0605 grey grass 0606 grey marsh 0706 dark-grey swamp 0806 dark-grey castle "Dolorous Garde"
Just paste it into Text Mapper.
