Package pymetatile is the pythonic-way library for reading/writing metatile files, translating Tile <-> Metatile coordinates.
For example, read specific tile data from metatile quite easy:
>>> import pymetatile
>>> with pymetatile.open("tests/data/0.meta", "rb") as mt:
... data = mt.readtile(1, 1)
... print(len(data))
10439pymetatile.open(filename, mode) opens file for reading ("rb" mode) or writing ("wb").
Support with statement, in statement, iterating over Points):
>>> import pymetatile
>>> mt = pymetatile.open("tests/data/0.meta", "rb")
>>> # check if tile (1, 2) contains in metatile
>>> print((1, 2) in mt, (10, 10) in mt)
True False
>>> # iterate over Points and print only points with x == 7
>>> for point in mt:
... if point.x == 7:
... print(point)
Point(x=7, y=0)
Point(x=7, y=1)
Point(x=7, y=2)
Point(x=7, y=3)
Point(x=7, y=4)
Point(x=7, y=5)
Point(x=7, y=6)
Point(x=7, y=7)
>>> # read all tiles data, iterate over Points and print only none-empty data:
>>> tiles_data = mt.readtiles()
>>> for point, data in tiles_data.items():
... if data:
... print(point, len(data))
Point(x=0, y=0) 25093
Point(x=0, y=1) 11330
Point(x=1, y=0) 26298
Point(x=1, y=1) 10439
>>> mt.close()Attributes:
- index: index table, dict {Point(x, y): Entry(offset, size), ...}
- header: header data, Header(count, x, y, z)
- size: square root of header.count
Methods:
- readtile(x, y) -> bytes
- readtiles() -> dict {Point(x, y): bytes, ...}
- write(x, y, z, data), where z is the metatile zoom level, x, y is the lowest values, data is the dict {Point(x, y): bytes, ...}
Methods:
- from_url(url) -> Metatile
- from_tile(Tile) -> Metatile
- filepath(basedir) -> str
>>> from pymetatile import Metatile, Tile
>>>
>>> tile = Tile(z=10, x=697, y=321, style="mapname", ext=".png")
>>> mt = Metatile.from_tile(tile)
>>> print(mt)
Metatile(z:10, hashes:[0, 0, 33, 180, 128], style:mapname)
>>> print(len(mt))
8
>>> print(mt.filepath("/cache"))
/cache/mapname/10/0/0/33/180/128.metaMethods:
- from_url(url) -> Tile
- from_metatile(mt) -> Tile
- filepath(url) -> str
>>> from pymetatile import Metatile, Tile
>>>
>>> mt = Metatile.from_url("mapname/10/0/0/0/0/0.meta")
>>> tile = Tile.from_metatile(mt)
>>> print(tile)
