module GoogleStaticMapsHelper
The Google Static Map
Helper provides a simple interface to the Google Static Maps V2 API (code.google.com/apis/maps/documentation/staticmaps/).
The module is build up of classes maping more or less directly to the entities you'd except:
Map

A map is what keeps all of the state of which you'll build a URL for.

One or more markers can be added to the map. A marker can be customized with size, label and color.

Usage:
# First of all, you might want to set your key etc GoogleStaticMapsHelper.key = 'your google key' GoogleStaticMapsHelper.size = '300x600' GoogleStaticMapsHelper.sensor = false # Then, you'll be able to do: url = GoogleStaticMapsHelper.url_for do marker :lng => 1, :lat => 2 marker :lng => 3, :lat => 4 path {:lng => 5, :lat => 6}, {:lng => 7, :lat => 7} end # You can send in key, size etc to url_for url = GoogleStaticMapsHelper.url_for(:key => 'your_key', :size => [300, 600]) do # ... end # If you need to, the map object is yielded to the block, so you can do: url = GoogleStaticMapsHelper.url_for do |map| map.marker object_which_responds_to_lng_lat end
# File lib/google_static_maps_helper.rb, line 61 def url_for(map_options = {}, &block) map = Map.new(map_options) block.arity < 1 ? map.instance_eval(&block) : block.call(map) map.url end
