Introduction

Spriter's Resource user Random Talking Brush extracted the images used to display the map in Legend of Zelda: Breath of the Wild, but it's all divided up into square tiles, and there are also separate tile variations for different states of the map. This Python 3 script stitches together the tiles into single images.

Basic Use

Note: This script requires Python 3.5 or above

First, make sure you have the actual map files (download here). Depending on what you want to do, you don't need to download them all.

• The "Map (Full)" archive contains everything needed to make a map at the highest quality (24,000x20,000 pixels) with all regions visible, although it will NOT have the complete Tarrey Town and Eldin Bridge will be up.
  • To get complete Tarrey Town and lowered Eldin Bridge, you can additionally download the "Map Variants (I-L)" archive.
• The "Map (Lower-Resolution)" archive contains everything needed to make 100% complete maps (i.e. all regions visible, Tarrey Town complete, and Eldin Bridge down) at any lower resolution
• The Variants archives contain the additional tiles needed to make highest-quality maps with regions missing.
• The "Map (Empty)" archive contains everything needed to make a completely empty map (i.e. just the background pattern and borders).

(For reference, here is what I mean when I talk about Tarrey Town and Eldin Bridge:)

VERY IMPORTANT!!!: Be sure to extract all of the archives into the same folder. The folder structure should look like this:

Legend of Zelda - Breath of the Wild\
  Map\
    Empty\
    Full\
  Map1\
    Empty\
    Full\
  Map2\
    Empty\
    Full\
  Map3\
    Empty\
    Full\

Finally, download stitchmap.py and flagmasks.txt. You can run the script like this:

python stitchmap.py <folder containing Map, Map1, etc.> [-o output_filename] [-l level_of_detail] [-r visible_regions] [-t tarrey_town_state] [-b bridge_state]

For more details on the parameters, see the "Argument Details" section. However, here are parameters for some of the most common commands:

• Full-quality map just with all regions visible (no tarrey town, bridge up): <folder> -l0 -r all -t0 -bup
• Full-quality 100% complete map (tarrey town complete, bridge down): <folder> -l0 -r all -t5 -bdown
• Lower-quality 100% complete map (tarrey town complete, bridge down): <folder> -l1 -r all -t5 -bdown
• Lowest-quality 100% complete map (tarrey town complete, bridge down) <folder> -l3 -r all -t5 -bdown
• Full-quality empty map (just the blue background pattern) <folder> -l0 -r none
• Lower-quality empty map (just the blue background pattern) <folder> -l1 -r none

Argument Details

-o, --output <filename>

Saves the generated image to <filename>. If this argument is not specified, the image will be saved to "output.png".

-l, --lod <number>

Specifies the level of detail (aka quality) of the generated image. 0 is the highest, and 3 is the lowest. Note that you need the "Map (Full)" archive for LOD 0, and the "Map (Lower-Resolution)" archive for LODs 1-3.

The image sizes for each level of detail are as follows:

LOD	Dimensions (px)	File Size (approx.)
0	24,000 x 20,000	~150 MiB
1	6720 x 5600	~17 MiB
2	2400 x 2000	~3 MiB
3	1080 x 900	~800 KiB

If this argument is not specified, it will default to 0 (highest quality).

-r, --regions <regions visible>

Specifies the regions that are visible on this map (you could also think of it as specifying the towers that have been activated). There are two special values for -r: "all" for a complete map, and "none" for an empty map. If you want a specific combination of regions, you need to enter a sequence of 1s and 0s where each digit represents a region. For example, if you want all regions except the Hebra and Great Plateau to be visible, the argument should look like this: -r 111111110111110.

The tower for each of the digits is as follows:

• nnnnnnnnnnnnnn1: Hebra Tower
• nnnnnnnnnnnnn1n: Tabantha Tower
• nnnnnnnnnnnn1nn: Gerudo Tower
• nnnnnnnnnnn1nnn: Wasteland Tower
• nnnnnnnnnn1nnnn: Woodland Tower
• nnnnnnnnn1nnnnn: Central Tower
• nnnnnnnn1nnnnnn: Great Plateau Tower
• nnnnnnn1nnnnnnn: Dueling Peaks Tower
• nnnnnn1nnnnnnnn: Lake Tower
• nnnnn1nnnnnnnnn: Eldin Tower
• nnnn1nnnnnnnnnn: Akkala Tower
• nnn1nnnnnnnnnnn: Lanayru Tower
• nn1nnnnnnnnnnnn: Hateno Tower
• n1nnnnnnnnnnnnn: Faron Tower
• 1nnnnnnnnnnnnnn: Ridgeland Tower

If this argument is not specified, it will default to all regions being visible.

-t, --tarreytown <number>

Specifies the state of Tarrey Town. In the game, the map will update to reflect the state of Tarrey Town, and there are a total of 6 states, from 0 (no houses) to 5 (complete). In the "Basic Use" section, you can see pictures of the 0 and 5 states.

If this argument is not specified, it will default to 5 (complete).

-b, --bridge up/down

Specifies the state of Eldin Bridge. Like Tarrey Town, the map will update in-game to reflect the state of Eldin Bridge; it can be up or down. In the "Basic Use" section, you can see pictures of the two states.

If this argument is not specified, it will default to down.
