*Disclaimer*
----------------

*Azure SDK Python packages support for Python 2.7 has ended 01 January 2022. For more information and questions, please refer to https://github.com/Azure/azure-sdk-for-python/issues/20691*

Getting started
---------------

Prerequisites
^^^^^^^^^^^^^


* Python 3.7 or later is required to use this package.
* An `Azure subscription <https://azure.microsoft.com/free/>`_ and an `Azure Maps account <https://docs.microsoft.com/azure/azure-maps/how-to-manage-account-keys>`_.
* A deployed Maps Services resource. You can create the resource via `Azure Portal <https://portal.azure.com>`_ or `Azure CLI <https://docs.microsoft.com/cli/azure>`_.

If you use Azure CLI, replace ``<resource-group-name>`` and ``<account-name>`` of your choice, and select a proper `pricing tier <https://docs.microsoft.com/azure/azure-maps/choose-pricing-tier>`_ based on your needs via the ``<sku-name>`` parameter. Please refer to `this page <https://docs.microsoft.com/cli/azure/maps/account?view=azure-cli-latest#az_maps_account_create>`_ for more details.

.. code-block:: bash

   az maps account create --resource-group <resource-group-name> --account-name <account-name> --sku <sku-name>

Install the package
^^^^^^^^^^^^^^^^^^^

Install the Azure Maps Service Render SDK.

.. code-block:: bash

   pip install azure-maps-render

Create and Authenticate the MapsRenderClient
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

To create a client object to access the Azure Maps Render API, you will need a **credential** object. Azure Maps Render client also support two ways to authenticate.

1. Authenticate with a Subscription Key Credential
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

You can authenticate with your Azure Maps Subscription Key.
Once the Azure Maps Subscription Key is created, set the value of the key as environment variable: ``AZURE_SUBSCRIPTION_KEY``.
Then pass an ``AZURE_SUBSCRIPTION_KEY`` as the ``credential`` parameter into an instance of `AzureKeyCredential <https://aka.ms/azsdk/python/core/azurekeycredential>`_.

.. code-block:: python

   from azure.core.credentials import AzureKeyCredential
   from azure.maps.render import MapsRenderClient

   credential = AzureKeyCredential(os.environ.get("AZURE_SUBSCRIPTION_KEY"))

   render_client = MapsRenderClient(
       credential=credential,
   )

2. Authenticate with an Azure Active Directory credential
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

You can authenticate with `Azure Active Directory (AAD) token credential <https://docs.microsoft.com/azure/azure-maps/how-to-manage-authentication>`_ using the `Azure Identity library <https://github.com/Azure/azure-sdk-for-python/blob/master/sdk/identity/azure-identity>`_.
Authentication by using AAD requires some initial setup:


* Install `azure-identity <https://aka.ms/azsdk/python/core/azurekeycredential>`_
* Register a `new AAD application <https://docs.microsoft.com/powershell/module/Az.Resources/New-AzADApplication?view=azps-8.0.0>`_
* Grant access to Azure Maps by assigning the suitable role to your service principal. Please refer to the `Manage authentication page <https://docs.microsoft.com/azure/azure-maps/how-to-manage-authentication>`_.

After setup, you can choose which type of `credential <https://aka.ms/azsdk/python/core/azurekeycredential>`_ from ``azure.identity`` to use.
As an example, `DefaultAzureCredential <https://github.com/Azure/azure-sdk-for-python/tree/main/sdk/identity/azure-identity#defaultazurecredential>`_
can be used to authenticate the client:

Next, set the values of the client ID, tenant ID, and client secret of the AAD application as environment variables:
``AZURE_CLIENT_ID``\ , ``AZURE_TENANT_ID``\ , ``AZURE_CLIENT_SECRET``

You will also need to specify the Azure Maps resource you intend to use by specifying the ``clientId`` in the client options. The Azure Maps resource client id can be found in the Authentication sections in the Azure Maps resource. Please refer to the `documentation <https://docs.microsoft.com/azure/azure-maps/how-to-manage-authentication#view-authentication-details>`_ on how to find it.

.. code-block:: python

   from azure.maps.render import MapsRenderClient
   from azure.identity import DefaultAzureCredential

   credential = DefaultAzureCredential()
   render_client = MapsRenderClient(
       client_id="<Azure Maps Client ID>",
       credential=credential
   )

Key concepts
------------

The Azure Maps Render client library for Python allows you to interact with each of the components through the use of a dedicated client object.

Sync Clients
^^^^^^^^^^^^

``MapsRenderClient`` is the primary client for developers using the Azure Maps Render client library for Python.
Once you initialized a ``MapsRenderClient`` class, you can explore the methods on this client object to understand the different features of the Azure Maps Render service that you can access.

Async Clients
^^^^^^^^^^^^^

This library includes a complete async API supported on Python 3.5+. To use it, you must first install an async transport, such as `aiohttp <https://pypi.org/project/aiohttp/>`_.
See `azure-core documentation <https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/core/azure-core/CLIENT_LIBRARY_DEVELOPER.md#transport>`_ for more information.

Async clients and credentials should be closed when they're no longer needed. These
objects are async context managers and define async ``close`` methods.

Examples
--------

The following sections provide several code snippets covering some of the most common Azure Maps Render tasks, including:


* `Get Maps Attribution <#get-maps-attribution>`_
* `Get Maps Static Image <#get-maps-static-image>`_
* `Get Maps Tile <#get-maps-tile>`_
* `Get Maps Tileset <#get-maps-tileset>`_
* `Get Maps Copyright for World <#get-maps-copyright-for-world>`_

Get Maps Attribution
^^^^^^^^^^^^^^^^^^^^

This request allows users to request map copyright attribution information for a
section of a tileset.

.. code-block:: python

   from azure.maps.render import MapsRenderClient

   result = maps_render_client.get_map_attribution(
       tileset_id=TilesetID.MICROSOFT_BASE,
       zoom=6,
       bounds=BoundingBox(
           south=42.982261,
           west=24.980233,
           north=56.526017,
           east=1.355233
       )
   )

Get Maps Tile
^^^^^^^^^^^^^

This request will return map tiles in vector or raster formats typically
to be integrated into a map control or SDK. Some example tiles that can be requested are Azure
Maps road tiles, real-time  Weather Radar tiles. By default, Azure Maps uses vector tiles for its web map
control (Web SDK) and Android SDK.

.. code-block:: python

   from azure.maps.render import MapsRenderClient

   result = maps_render_client.get_map_tile(
       tileset_id=TilesetID.MICROSOFT_BASE,
       z=6,
       x=9,
       y=22,
       tile_size="512"
   )

Get Maps Tileset
^^^^^^^^^^^^^^^^

This request will give metadata for a tileset.

.. code-block:: python

   from azure.maps.render import MapsRenderClient

   result = maps_render_client.get_map_tileset(tileset_id=TilesetID.MICROSOFT_BASE)

Get Maps Static Image
^^^^^^^^^^^^^^^^^^^^^

This request will provide the static image service renders a user-defined, rectangular image containing a map section
using a zoom level from 0 to 20.
The static image service renders a user-defined,
rectangular image containing a map section using a zoom level from 0 to 20.
And also save the result to file as png.

.. code-block:: python

   from azure.maps.render import MapsRenderClient

   result = maps_render_client.get_map_static_image(img_format="png", center=(52.41064,4.84228))
   # Save result to file as png
   file = open('result.png', 'wb')
   file.write(next(result))
   file.close()

Get Maps Copyright for World
^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This request will serve copyright information for Render Tile service.

.. code-block:: python

   from azure.maps.render import MapsRenderClient

   result = maps_render_client.get_copyright_for_world()

Troubleshooting
---------------

General
^^^^^^^

Maps Render clients raise exceptions defined in `Azure Core <https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/core/azure-core/README.md>`_.

This list can be used for reference to catch thrown exceptions. To get the specific error code of the exception, use the ``error_code`` attribute, i.e, ``exception.error_code``.

Logging
^^^^^^^

This library uses the standard `logging <https://docs.python.org/3/library/logging.html>`_ library for logging.
Basic information about HTTP sessions (URLs, headers, etc.) is logged at INFO level.

Detailed DEBUG level logging, including request/response bodies and unredacted headers, can be enabled on a client with the ``logging_enable`` argument:

.. code-block:: python

   import sys
   import logging
   from azure.maps.render import MapsRenderClient

   # Create a logger for the 'azure.maps.render' SDK
   logger = logging.getLogger('azure.maps.render')
   logger.setLevel(logging.DEBUG)

   # Configure a console output
   handler = logging.StreamHandler(stream=sys.stdout)
   logger.addHandler(handler)
