minetestmapper - generate an overview image of a Luanti map

minetestmapper  generates  an  overview  image  of  a  Luanti  map.  This  is  a  port  of  the  original
       minetestmapper.py to C++, that is both faster and provides more functionality than  the  obsolete  Python
       script.

-iworld_path
              Input world path.

       -ooutput_image

--bgcolorcolor
              Background color of image, e.g. "--bgcolor #ffffff"

       --scalecolorcolor
              Color of scale, e.g. "--scalecolor #000000"

       --playercolorcolor
              Color of player indicators, e.g. "--playercolor #ff0000"

       --origincolorcolor
              Color of origin indicator, e.g. "--origincolor #ff0000"

       --drawscale
              Draw tick marks

       --drawplayers
              Draw player indicators

       --draworigin
              Draw origin indicator

       --drawalpha
              Allow nodes to be drawn with transparency

       --noshading
              Don't draw shading on nodes

       --noemptyimage
              Don't output anything when the image would be empty.

       --min-ynumber
              Don't draw nodes below this y value, e.g. "--min-y -25"

       --max-ynumber
              Don't draw nodes above this y value, e.g. "--max-y 75"

       --backendbackend
              Use specific map backend; supported: sqlite3, leveldb, redis, postgresql, e.g. "--backend leveldb"

       --geometrygeometry
              Limit  area  to  specific  geometry  (x:y+w+h  where  x and y specify the lower left corner), e.g.
              "--geometry -800:-800+1600+1600"

       --extent
              Don't render the image, just print the extent of the map that would  be  generated,  in  the  same
              format as the geometry above.

       --zoomfactor
              Zoom the image by using more than one pixel per node, e.g. "--zoom 4"

       --colorspath
              Forcefully    set   path   to   colors.txt   file   (autodetected   otherwise),   e.g.   "--colors
              ../world/mycolors.txt"

       --scalesedges
              Draw scales on specified image edges (letters tblr meaning top, bottom, left and  right),  e.g.
              "--scales tbr"

       --exhaustivemode
              Select  if  database should be traversed exhaustively or using range queries, available: never, y,
              full, auto

              Defaults to auto. You shouldn't need to change this, but doing so can improve rendering  times  on
              large maps.  For these optimizations to work it is important that you set min-y and max-y when you
              don't care about the world below e.g. -60 and above 1000 nodes.

       --dumpblockpos
              Instead  of  rendering  anything try to load the block at the given position (x,y,z) and print its
              raw data as hexadecimal.
