papyrus_tilecache

papyrus_tilecache provides an easy and convenient method for embeding TileCache in Pyramid applications.

The source code of papyrus_tilecache is straightforward, so if papyrus_tilecache doesn't do what you want, open its source code, get inspiration, and write your own code.

Install

papyrus_tilecache can be installed with easy_install::

$ easy_install papyrus_tilecache

Often you'll want to make papyrus_tilecache a dependency of your Pyramid application, which is done by adding papyrus_tilecache to the install_requires list defined in the Pyramid application's setup.py file.

Embed TileCache

Embeding TileCache in a Pyramid application is easy.

Edit the application's development.ini file and, in the main section ([app:]), set tilecache.cfg to the location of the TileCache config file. Example::

[app:MyApp]
use = egg:MyApp
...
tilecache.cfg = %(here)s/tilecache.cfg

In this example the TileCache config file is located at the same location as the development.ini file.

You can use the following TileCache config as an example::

[cache]
type=Disk
base=/tmp/tilecache
[basic]
type=WMS
url=http://vmap0.tiles.osgeo.org/wms/vmap0
extension=png

Now, edit the application's main file, __init__.py, and register papyrus_tilecache using the Configurator.include method::

def main(global_config, **settings):

    config = Configurator(settings=settings)

    import papyrus_tilecache
    config.include(papyrus_tilecache)

That's it! The Pyramid application now exposes a TileCache service at /tilecache.
