Export raster map with tillmill from command line
Octave-Script to calculate bounding box for tilemill from center (lon,lat), zoomlevel and scalefactor:
lon = 13.74921;
lat = 51.07545;
z = 16; %zoomlevel
sf = 3; %scalefactor
width= 18000 %256*sf;
height= 3200 %256*sf;
C = 40040; % the (equatorial) circumference of the Earth
londegree_per_pixel = 360 / 2^(8+z)*cos(lat/180*pi) / sf;
latdegree_per_pixel = 180 / 2^(8+z) / sf;
%bbox:
xmin = lon - width/2 * londegree_per_pixel;
ymin = lat - height/2 * latdegree_per_pixel;
xmax = lon + width/2 * londegree_per_pixel;
ymax = lat + height/2 * latdegree_per_pixel;

outcmd = sprintf('node ~/tilemill/index.js export openstreetmap-carto --format png --bbox="%f,%f,%f,%f" --width %d --height %d --scale %f bellabike.png\n', xmin,ymin,xmax,ymax,width,height,sf);

- Installe node version manager (nvm) and switch to node v6.14.1 (node-mapnik doesn't provide binaries for newest node)
- Create ~/kosmtik, go there and
npm install kosmtik
cd ~/src/kosmtik node index.js export ~/Documents/kosmtik/openstreetmap-carto-4.9.0/project.mml --output=/home/nils/Documents/kosmtik/export --format tiles --maxZoom 17 --minZoom 5 --bounds="13.346,50.249,14.872,51.237"
