yandex-hotspots 0.1

Yandex Hotsposts

Python library to generate tiles and js for Yandex Maps Hotspots version 2. Beware, hotspots js api is not documented well. Use at your own risk. Works on python 2.6-2.7.

It’s a fork of an app by Paul Koltyshev, called django-hotspots. yandex-hotspots is written to support new version of hotspots API and primarily to be django-free package.

This lib supports only simplest of hotspots: points.

Usage

Subclass HotspotsManager and define at least these methods:

from PIL import Image
from hotspots import HotspotsManager


class MyHotspotsManager(HotspotsManager):
    img_big = Image.open('static/images/big_marker.png')
    img_small = Image.open('static/images/small_marker.png')

    def get_base_path(self):
        """ Where to save tiles"""
        return 'static/hotspots'

    def get_img(self, obj, scale):
        """ Hotspot image object"""
        return self.img_big if scale > 12 else self.img_small

    def get_lng(self, obj):
        """ Latitude of your object"""
        return obj.coordinates[0]

    def get_lat(self, obj):
        """ Longitude """
        return obj.coordinates[1]

Run hotspot generator:

# Obtain data for hotspots (some locations with data)
data_iterable = [{'coordinates': (37.925288, 55.720903), 'title': 'My House'}, <...>]

# Generate hotspots for zoom levels raging form 10 to 17
MyHotspotsManager().generate_tiles(data_iterable, scale=(10, 17))

And finally put together created hotspots and some clientside.

Ballon content and hint

Use gett_descr(self, obj) and get_name(self, obj) respectively.
