tile-renderer 1.2

Leaflet.js streetmap tile renderer

tile-renderer

Leaflet.js streetmap tile renderer, made by 7d

Note: renderer is complete, but not the skin or the tutorials.

Documentation: https://tile-renderer.readthedocs.io/en/latest/

Current version: v1.2

• v1.2 (8/5/21)
  • renderer.render() now ignores PLAs if their type is not specified in the skin Json
  • Hollows are now supported in areas
  • New function, renderer.validate.vGeoJson()
    • renderer.validate.vCoords() now supports lists along with tuples
  • The renderer now has a CLI, to show the help page do python -m renderer -h
  • renderer.render() now supports float maxZoomRanges
  • New functions: renderer.tools.plaJson.toGeoJson() and renderer.tools.geoJson.toNodePlaJson()
    • these are for translating our custom format of storing geographical format to geoJson
    • (btw why we're not using geoJson is because its harder to store nodes)
  • internal-use files have been moved to renderer/internals/
  • removed renderer.tools.plaJson.toTiles() as it's a duplicate of renderer.tools.plaJson.renderedIn()
  • renderer.tools.coord.toTiles() now supports tuples as coords parameter
• v1.3 (coming soon)
  • Long label breaking
  • Validating from CLI (& more)
  • Fixing texts for once
  • Skin installer
• Past changelogs can be found in https://tile-renderer.readthedocs.io/en/latest/changelog.html

Usage (simple)

1. Download or clone this repo; or run pip install tile-renderer
2. Write a node JSON file and a PLA JSON file. (Tutorial coming soon) Or, use the example files provided in data.
3. In your file, run the renderer. Here is an example code:

import renderer # important!!
import json

def readFile(dir): # extract from JSON as dict
    with open(dir, "r") as f:
        data = json.load(f)
        f.close()
        return data

pla = readFile("path_to_your_PLA_file/pla.json")
nodes = readFile("path_to_your_nodes_file/nodes.json")
skin = renderer.misc.getSkin("default")

if __name__ == "__main__": renderer.render(pla, nodes, skin, 1, 2, 8)
# renders tiles at zoom levels 1 and 2 with the max zoom tile covering 8 units
# Don't like clogging the main directory? Create a new folder and use this instead:
# if __name__ == "__main__": renderer.render(pla, nodes, skin, 1, 2, 8, saveDir="your_folder_name/")
# Too slow? Increase the number of processes
# if __name__ == "__main__": renderer.render(pla, nodes, skin, 1, 2, 8, processes=5)
