Generates large resolution images of a Minecraft map. Github code repository:
http://github.com/overviewer/Minecraft-Overviewer
In short, this program reads in Minecraft world files and renders very large
resolution images that can be viewed through a Google Maps interface. It
performs a similar function to the existing Minecraft Cartographer program but
with a slightly different goal in mind: to generate large resolution images
such that one can zoom in and see details.
See some examples here! The Minecraft Overviewer is a command-line tool for rendering high-resolution
http://github.com/overviewer/Minecraft-Overviewer/wiki/Map-examples maps of Minecraft worlds. It generates a set of static html and image files and
uses the Google Maps API to display a nice interactive map.
Further documentation may be found at The Overviewer has been in active development for over a year and has many
https://github.com/overviewer/Minecraft-Overviewer/wiki/Documentation features, including day and night lighting, cave rendering, mineral overlays,
and many plugins for even more features! It is written mostly in Python with
critical sections in C as an extension module.
To contact the developers and other users, go to the site at the top of this Getting Started
README, or go to #overviewer on irc.freenode.net. ---------------
All documentation has been consolidated at our documentation site. For

Textures
--------
The Overviewer uses actual textures to render your world. However, I don't
include textures in the package. You will need to do one of two things before
you can use the Overviewer:
* Make sure the Minecraft client is installed. The Overviewer will find the
installed minecraft.jar and extract the textures from it.
* Install a texture file yourself. This file is called "terrain.png" and is
normally found in your minecraft.jar file (not "Minecraft.jar", the launcher,
but rather the file that's downloaded by the launcher and installed into a
hidden directory). You can also get this file from any of the third party
texture packs out there.
Biome Tinting
-------------
With the Halloween update, biomes were added to Minecraft. In order to get
biome-accurate tinting, the Overviewer can use biome data produced by the
Minecraft Biome Extractor tool. This tool can be downloaded from:
http://www.minecraftforum.net/viewtopic.php?f=25&t=80902
If the "biomes" folder is present in the world directory, then the Overviewer
will use the biome data to tint grass and leaves automatically -- there is no
command line option to turn this feature on. If this folder does not exist,
then the Overviewer will use a static tinting for grass and leaves.
Compiling the C Extension
-------------------------
The C Extension for Overviewer is no longer optional. In addition to
providing a higher quality image compositing function that looks better on
maps with lighting enabled, it now does the bulk of the rendering.
If you downloaded Overviewer as a binary package, this extension will already
be compiled for you.
If you have a C compiler and the Python development libraries set up, you can
compile this extension like this::
python setup.py build
Note that you need the development headers for your version of Python installed,
look for a package named 'python-dev', 'python-devel' or similar. Also, some
Python distributions do not install "Imaging.h" and "ImPlatform.h" properly. If
you get errors complaining about them, you can get them from the PIL source, or
at <http://svn.effbot.org/public/tags/pil-1.1.7/libImaging/>. Just put them in
the same directory as "overviewer.py".
For more detailed instructions, check the wiki:
https://github.com/overviewer/Minecraft-Overviewer/wiki/Build-Instructions
Running
-------
To generate a set of Google Map tiles, use the overviewer.py script like this::
python overviewer.py [OPTIONS] <World # / Name / Path to World> <Output Directory>
The output directory will be created if it doesn't exist. This will generate a
set of image tiles for your world in the directory you choose. When it's done,
you will find an index.html file in the same directory that you can use to view
it.
Options
-------
-h, --help
Shows the list of options and exits
--advanced-help
Display help - including advanced options
-p PROCS, --processes=PROCS
Adding the "-p" option will utilize more cores during processing. This
can speed up rendering quite a bit. The default is set to the same
number of cores in your computer, but you can adjust it.
Example to run 5 worker processes in parallel::
python overviewer.py -p 5 <Path to World> <Output Directory>
-d, --delete
This option changes the mode of execution. No tiles are rendered, and
instead, files are deleted.
*Note*: Currently only the overviewer.dat file is deleted when you run with
this option
--forcerender
Force re-rendering the entire map (or the given regionlist). This
is an easier way to completely re-render without deleting the map.
--regionlist=regionlist
Use this option to specify manually a list of regions to consider for
updating. Without this option, every chunk in every region is checked for
update and if necessary, re-rendered. If this option points to a file
containing, 1 per line, the path to a region data file, then only those
in the list will be considered for update.
It's up to you to build such a list. On Linux or Mac, try using the "find"
command. You could, for example, output all region files that are older than
a certain date. Or perhaps you can incrementally update your map by passing
in a subset of regions each time. It's up to you!
--rendermodes=MODE1[,MODE2,...]
Use this option to specify which render mode to use, such as lighting or
night. Use --list-rendermodes to get a list of available rendermodes, and
a short description of each. If you provide more than one mode (separated
by commas), Overviewer will render all of them at once, and provide a
toggle on the resulting map to switch between them.
If for some reason commas do not work for your shell (like if you're using
Powershell on Windows), you can also use a colon ':' or a forward slash '/'
to separate the modes.
--list-rendermodes
List the available render modes, and a short description of each.
--north-direction=NORTH_DIRECTION
Specifies which corner of the screen north will point to.
Valid options are: lower-left, upper-left, upper-right, lower-right.
If you do not specify this option, it will default to whatever direction
the existing map uses. For new maps, it defaults to lower-left for
historical reasons.
--settings=PATH
Use this option to load settings from a file. The format of this file is
given below.
Settings
--------
You can optionally store settings in a file named settings.py (or really,
anything you want). It is a regular python script, so you can use any python
functions or modules you want. To use a settings file, use the --settings
command line option.
For a sample settings file, look at 'sample.settings.py'. Note that this file
is not meant to be used directly, but instead it should be used as a
collection of examples to guide writing your own.
Here's a (possibly incomplete) list of available settings, which are available
in settings.py. Note that you can also set command-line options in a similar
way.
imgformat=FORMAT
Set the output image format used for the tiles. The default is 'png',
but 'jpg' is also supported.
zoom=ZOOM
The Overviewer by default will detect how many zoom levels are required
to show your entire map. This option sets it manually.
*You do not normally need to set this option!*
This is equivalent to setting the dimensions of the highest zoom level. It
does not actually change how the map is rendered, but rather *how much of
the map is rendered.* Setting this option too low *will crop your map.*
(Calling this option "zoom" may be a bit misleading, I know)
To be precise, it sets the width and height of the highest zoom level, in
tiles. A zoom level of z means the highest zoom level of your map will be
2^z by 2^z tiles.
This option map be useful if you have some outlier chunks causing your map
to be too large, or you want to render a smaller portion of your map,
instead of rendering everything.
Remember that each additional zoom level adds 4 times as many tiles as
the last. This can add up fast, zoom level 10 has over a million tiles.
Tiles with no content will not be rendered, but they still take a small
amount of time to process.
web_assets_hook
This option lets you define a function to run after the web assets have
been copied into the output directory, but before any tile rendering takes
place. This is an ideal time to do any custom postprocessing for
markers.js or other web assets.
This function should accept one argument: a QuadtreeGen object.
web_assets_path
This option lets you provide alternative web assets to use when
rendering. The contents of this folder will be copied into the output folder
during render, and will overwrite any default files already copied by
Overviewer. See the web_assets folder included with Overviewer for the
default assets.
textures_path
This is like web_assets_path, but instead it provides an alternative texture
source. Overviewer looks in here for terrain.png and other textures before
it looks anywhere else.
north_direction
Specifies which corner of the screen north will point to.
Valid options are: lower-left, upper-left, upper-right, lower-right.

Crushing the Output Tiles
-------------------------
Image files taking too much disk space? Try using pngcrush. On Linux and
probably Mac, if you have pngcrush installed, this command will go and crush
all your images in the given destination. This took the total disk usage of the
render for my world from 85M to 67M.
::
find /path/to/destination -name "*.png" -exec pngcrush {} {}.crush \; -exec mv {}.crush {} \;
Or if you prefer a more parallel solution, try something like this::
find /path/to/destination -print0 | xargs -0 -n 1 -P <nr_procs> sh -c 'pngcrush $0 temp.$$ && mv temp.$$ $0'
If you're on Windows, I've gotten word that this command line snippet works
provided pngout is installed and on your path. Note that the % symbols will
need to be doubled up if this is in a batch file.

Skip the generation and output of markers.js and regions.js to the output
directory.
**Settings file:**
Option name: ``skipjs``
Format: Boolean
Default: False
.. cmdoption:: --textures-path <path>
Use this option to specify an alternate terrain.png to use for textures when
rendering a world. ``path`` specifies the **containing directory** of
terrain.png.
The Overviewer will look for terrain.png in the following places in this
order: path specified by this option, the program's directory, the
overviewer_core/data/textures directory within the source directory, the
default textures that come with Minecraft if it's installed.

When The Overviewer runs, it copies the files from the web_assets directory
to the destination directory. If you wish to override a file with your own,
for example, to make changes, you may put your modified copies in your own
directory and specify the directory with this option.
Files in the folder specified by ``path`` will override files from the
web_assets directory, letting you customize the files.
If you're running from source and are comfortable merging with Git, it may
be better to edit the web_assets directly. If we update one of the files,
you can use Git to merge in our changes with yours.
If, however, you do not like Git, and don't mind having to manually update
or merge web assets (or don't care for web asset updates at all), then copy
all the web assets to a directory of your own and use this option.

Settings File
=============
You can optionally store settings in a file named settings.py (or really,
anything you want). It is a regular python script, so you can use any python
functions or modules you want. To use a settings file, use the
:option:`--settings` command line option when you run the Overviewer.
For a sample settings file, look at 'sample.settings.py'. Note that this file is
not meant to be used directly, but instead it should be used as a collection of
examples to guide writing your own. It contains a number of examples to get you
started, but you almost certainly don't want to use it as-is.
You can specify *any of the above* options in your settings file *in addition to
the ones documented below*. For the command-line options, find its listed
"Option name" which is the Python identifier you will use. For example, if you
wanted to specify :option:`--bg-color`, you would look and see its option name
is "bg_color" (note the underscore) and you would put this line in your settings
file::
bg_color = "#000000"

Render Modes Render Modes
============ ============
.. _rendermode-options: https://github.com/agrif/Minecraft-Overviewer/tree/rendermode-options A rendermode is a unique way of rendering a Minecraft map. The normal render
mode was the original, and we've since added a render mode with proper lighting,
a rendermode for nighttime lighting, and we have a rendermode that only shows
caves.
Rendermode options are a new way of changing how existing render modes Beyond that, there are also render "overlays" that can be toggled on or off,
work, by passing in values at startup. For example, you can change how overlaying a proper rendering. These can be used to show where minerals are and
dark the 'night' mode is, or enable lighting in 'cave' mode. such.

rendermodes installed with :option:`--list-rendermodes`.

---------------------------
Sometimes, you want to render two map layers with the same mode, but with two
different sets of options. For example, you way want to render a cave mode with
depth tinting, and another cave mode with lighting and no depth tinting. In this
case, you will want to define a 'custom' render mode that inherits from 'cave'
and uses the options you want. For example::
custom_rendermodes = {
'cave-lighting': {
'parent': 'cave',
'label': 'Lit Cave',
'description': 'cave mode, with lighting',
'options': {
'depth_tinting': False,
'lighting': True,

},
}

Each entry in ``custom_rendermodes`` starts with the mode name, and is followed
by a dictionary of mode information, such as the parent mode and description
(for your reference), a label for use on the map, as well as the options to
apply.
Every custom rendermode you define is on exactly equal footing with the built-in
modes: you can put them in the ``rendermode`` list to render them, you can
inherit from them in other custom modes, and you can even add options to them

Customizing Web Assets
======================
The web assets are the static html files stored in
overviewer_core/data/web_assets that are copied to the destination directory
when you run the Overviewer. Some of these files are actually templates and
certain parameters are set at render time depending on various factors. Others
are just straight up copied.
You should not typically need to edit the files in here, but if you like
customizing things or want to edit them for whatever reason, here's two ways:
1. If you're not afraid of Git and you're running the Overviewer from a Git
clone of our repository, you can edit the files in
overviewer_core/data/web_assets directly. When you pull in changes from us,
you will have to merge, but using Git should make this relatively painless.
2. Otherwise, the recommended way is to use the :option:`--web-assets-path`
option. Use this option and point it to a directory of customized web assets
to copy.
Files from the original web_assets directory are still copied, but any files
in the custom web assets directory will override the originals. This way you
can customize a few files and leave the rest alone.
The downside is, if you want to upgrade you will have to merge in your
changes with any of our changes manually. To avoid merging entirely, just
copy *all* the web assets to your custom web assets folder. You'll keep the
old version of all files for eternity, missing out on new features we may
add, but you won't have to deal with merges at all.
