NBT-Cpp

=======

The NBT::Tag class is a class to load, create, modify, save, and print NBT files.

From Notch's original spec:

> NBT (Named Binary Tag) is a tag based binary format designed to carry large amounts of binary data with smaller amounts of additional data.

Features

--------

- read raw filestream

- read gzip filestream

- read byte array

- get tag name

- get tag type

- get tag value

- get compound subtag

- get list item

- get tag content as string

- print tag tree as json

- read region chunk

To do list

----------

- read region timestamps

- write raw filestream

- write gzip filestream

- write region chunk

Included programs

![worldmap example](http://lunarco.de/minecraft/nbt-worldmap_Songburrow_+450-2050_500x700_2x2.png)

####`worldmap.cpp`

Takes a minecraft world path and renders the map into `worldmap.png`.

Rendered are `width` by `height` blocks around the `center`, each block `zoom` by `zoom` pixels large.

Optionally prints `center x`, `center z`, `width`, and `height` of the map.

The current color data is from the default texture pack, slightly adjusted by me.

The renderer even calculates block transparency and does a bit of height mapping.

**Arguments:**

` [center x=0] [center z=0] [width=256] [height=256] [zoom=1] [info text size=10]`

- `worldpath`: The path to the Minecraft world.

    - Example: `saves/Legio-Umbra/`

- `center x`: The x coordinate of the block at the center of the image.

    - Example: `500`

- `center z`: The z coordinate of the block at the center of the image.

    - Example: `-432`

- `width`: The x range of the blocks in the image.

    - Example: `600`

- `height`: The z range of the blocks in the image.

    - Example: `400`

- `zoom`: The size of each map pixel.

    - Example: `5`

- `info text size`: The font size to use for the info text. `0` for no text.

    - Example: `12`

**Example:**

`worldmap saves/Legio-Umbra/ 500 -432 600 400 5 12`

Renders `saves/Legio-Umbra/` with `5x5` block size and prints various data in font size `12`.

The image contains all blocks from 200,-632 to 799,-231.

####`main.cpp`

Prints a json-like tree of the provided file.

Supports uncompressed and gzip compressed files.

**Arguments:**

` [tag path=""]`

- `path/to/file`: The file to load the tag from.

    - Example: `testdata/bigtest.nbt`

- `tag path`: The path to the tag that will be printed.

    - Example: `nested compound test.ham.name`

**Example:**

`main bigtest.nbt`

Prints the content of `bigtest.nbt`, which is too long and can be found here: 

####`map.cpp`

Takes a minecraft world path and map id and renders the map item into `map_#.png`.

Optionally prints `scale`, `dimension`, `xCenter` and `zCenter` of the map.

**Arguments:**

`  [zoom=5] [info text size=0]`

- `worldpath`: The path to the Minecraft world.

    - Example: `saves/Legio-Umbra/`

- `mapnr`: The id of the map item.

    - Example: `4`

- `zoom`: The size of each map pixel.

    - Example: `5`

- `info text size`: The font size to use for the info text. `0` for no text.

    - Example: `12`

**Example:**

`map saves/Legio-Umbra/ 4 5 12`

Renders `saves/Legio-Umbra/data/map_4.dat` with `5x5` pixel size and prints various map data in font size `12`.
