Minetest Mapper C++
===================

.. 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.
This version is both faster and provides more features than the now deprecated Python script.

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

* libgd
* sqlite3
* LevelDB (optional, set ENABLE_LEVELDB=1 in CMake to enable)
* hiredis library (optional, set ENABLE_REDIS=1 in CMake to enable)
* Postgres libraries (optional, set ENABLE_POSTGRES=1 in CMake to enable)

e.g. on Debian:
^^^^^^^^^^^^^^^

	sudo apt-get install libgd-dev libsqlite3-dev libleveldb-dev libhiredis-dev libpq-dev

Windows
^^^^^^^
Minetestmapper for Windows can be downloaded here: https://github.com/minetest/minetestmapper/releases

After extracting the archive, minetestmapper can be invoked from cmd.exe:
::

	cd C:\Users\yourname\Desktop\example\path
	minetestmapper.exe --help

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

::

    cmake . -DENABLE_LEVELDB=1
    make -j2

Usage
-----

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

::

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


Parameters
^^^^^^^^^^

bgcolor:
    Background color of image, e.g. ``--bgcolor '#ffffff'``

scalecolor:
    Color of scale marks and text, e.g. ``--scalecolor '#000000'``

playercolor:
    Color of player indicators, e.g. ``--playercolor '#ff0000'``

origincolor:
    Color of origin indicator, e.g. ``--origincolor '#ff0000'``

drawscale:
    Draw scale(s) with tick marks and numbers, ``--drawscale``

drawplayers:
    Draw player indicators with name, ``--drawplayers``

draworigin:
    Draw origin indicator, ``--draworigin``

drawalpha:
    Allow nodes to be drawn with transparency (e.g. water), ``--drawalpha``

extent:
    Don't output any imagery, just print the extent of the full map, ``--extent``

noshading:
    Don't draw shading on nodes, ``--noshading``

noemptyimage:
    Don't output anything when the image would be empty, ``--noemptyimage``

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

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

backend:
    Override auto-detected map backend; supported: *sqlite3*, *leveldb*, *redis*, *postgresql*, e.g. ``--backend leveldb``

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

tilesize:
    Don't output one big image, but output tiles of the specified size, e.g. "--tilesize 128x128". The sizes will be rounded to
    a multiple of 16. The filenames will be created in the form <x>_<y>_<filename>, where <x> and <y>
    are the tile numbers and <filename> is the name specified with -o. Skip empty tiles by also specifying --noemptyimage.

zoom:
    Apply zoom to drawn nodes by enlarging them to n*n squares, e.g. ``--zoom 4``

colors:
    Override auto-detected path to colors.txt, e.g. ``--colors ../minetest/mycolors.txt``

scales:
    Draw scales on specified image edges (letters *t b l r* meaning top, bottom, left and right), e.g. ``--scales tbr``
