How do you achieve the shaded heightmap effect in the final image? (gallery04_large.jpg)
I would love an --export-heightmap option, hoping to generate a 3d terrain with map.

I know this is an old repo, but in case someone still looks at it...
Is it possible for someone to make a build and put it in the project "releases"
That way people dont have to know how to get it all set up and running to build it themselves (i always get headaches when i try) and can just download the build.

Is it possible to have complete islands and prevent the edges cropping?

Thanks for fixing the string conversion bug. Now i bumped into another one that is probably 3.x specific.
EDIT: Nope, that also happens on 2.7!

I could build the binary now, but it couldn't import the render module:

ModuleNotFoundError: No module named 'render'

So, i searched a bit and i think it is related to the CWD not being in the current sys.path:
Stackoverflow about sys.path with pyimport

I tried adding it but failed because the _get_PyString_fromString function returns a bytes.
So i did it via

PyRun_SimpleString("sys.path.append('/home/riot/src/FantasyMapGenerator/build')");

and it was able to import ther render module.

Afterwards i ran into two problems:

• 3.5 - "Error: function not in module dict"
• 3.6 - couldn't import cairo, probably a cairo bug: ModuleNotFoundError: No module named 'cairo._cairo'

I'd rather not open tickets for those, as i don't know whats going on with 3.5 and i think the 3.6-one is not related to this project. Help would be appreciated ;)

I was trying to install your package, but when running make I encountered the following.

/my/path/FantasyMapGenerator/src/render.cpp: In function ‘void gen::render::drawMap(std::vector<char>&, std::__cxx11::string)’:
/my/path/FantasyMapGenerator/src/render.cpp:17:75: error: ‘PyString_FromString’ was not declared in this scope

Any thoughts on resolving?

It would be rather convenient to have the ability to output in SVG format, since SVG files are much more friendly for editing and scaling. I tried adding that to Python rendering script (using svgwrite library), but it became painfully slow once I added the slope lines to output.
In the end I hacked something together in C++, adding the MapGenerator::outputSvgData and a couple of small helper functions to MapGenerator class.
SVG generation is pretty straight-forward, and it comes with an unexpected benefit of not having to calculate and pass label text extents for background covering, since SVG filtering can be employed to do that automagically. I used to a simple semi-opaque white to cover label backgrounds, but the specifics are easily editable.
Patch and a couple of output SVG files (B&W vs color) are attached. I verified those SVG files by opening and editing them in Inkscape, in case your SVG viewer of choice is giving you trouble.
Thanks for an awesome application and a great educational write-up on how it all works together!
