**ATTRIBUTES**
|
|
|
|
* ``apertures`` (dict): The keys are names/identifiers of each aperture.
|
|
The values are dictionaries key/value pairs which describe the aperture. The
|
|
type key is always present and the rest depend on the key:
|
|
|
|
+-----------+-----------------------------------+
|
|
| Key | Value |
|
|
+===========+===================================+
|
|
| type | (str) "C", "R", "O", "P", or "AP" |
|
|
+-----------+-----------------------------------+
|
|
| others | Depend on ``type`` |
|
|
+-----------+-----------------------------------+
|
|
| solid_geometry | (list) |
|
|
+-----------+-----------------------------------+
|
|
* ``aperture_macros`` (dictionary): Are predefined geometrical structures
|
|
that can be instantiated with different parameters in an aperture
|
|
definition. See ``apertures`` above. The key is the name of the macro,
|
|
and the macro itself, the value, is a ``Aperture_Macro`` object.
|
|
|
|
* ``flash_geometry`` (list): List of (Shapely) geometric object resulting
|
|
from ``flashes``. These are generated from ``flashes`` in ``do_flashes()``.
|
|
|
|
* ``buffered_paths`` (list): List of (Shapely) polygons resulting from
|
|
*buffering* (or thickening) the ``paths`` with the aperture. These are
|
|
generated from ``paths`` in ``buffer_paths()``.
