===================

.. image:: https://travis-ci.org/minetest/minetestmapper.svg?branch=master
    :target: https://travis-ci.org/minetest/minetestmapper

A port of minetestmapper.py to C++ from https://github.com/minetest/minetest/tree/master/util

Requirements
------------

* libgd
* sqlite3
* leveldb (optional, set ENABLE_LEVELDB=1 in CMake to enable leveldb support)
* hiredis (optional, set ENABLE_REDIS=1 in CMake to enable redis support)

Compilation
-----------

::

    cmake .
    make

Usage
-----

Binary `minetestmapper` has two mandatory paremeters, `-i` (input world path)
and `-o` (output image path).

::

    ./minetestmapper -i ~/.minetest/worlds/my_world/ -o ~/map.png

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

backend:
    Use specific map backend, supported: *sqlite3*, *leveldb*, *redis*, e.g. ``--backend leveldb``
