Reorder¶
Tools to reorder DXF entities by handle or a special sort handle mapping.
Such reorder mappings are stored only in layouts as Modelspace,
Paperspace or BlockLayout,
and can be retrieved by the method get_redraw_order().
Each entry in the handle mapping replaces the actual entity handle, where the “0” handle has a special meaning, this handle always shows up at last in ascending ordering.
-
ezdxf.reorder.ascending(entities: Iterable[DXFGraphic], mapping: Union[Dict, Iterable[Tuple[str, str]]] = None) → Iterable[DXFGraphic]¶ Yields entities in ascending handle order.
The sort handle doesn’t have to be the entity handle, every entity handle in mapping will be replaced by the given sort handle, mapping is an iterable of 2-tuples (entity_handle, sort_handle) or a dict (entity_handle, sort_handle). Entities with equal sort handles show up in source entities order.
- Parameters
entities – iterable of
DXFGraphicobjectsmapping – iterable of 2-tuples (entity_handle, sort_handle) or a handle mapping as dict.
-
ezdxf.reorder.descending(entities: Iterable[DXFGraphic], mapping: Union[Dict, Iterable[Tuple[str, str]]] = None) → Iterable[DXFGraphic]¶ Yields entities in descending handle order.
The sort handle doesn’t have to be the entity handle, every entity handle in mapping will be replaced by the given sort handle, mapping is an iterable of 2-tuples (entity_handle, sort_handle) or a dict (entity_handle, sort_handle). Entities with equal sort handles show up in reversed source entities order.
- Parameters
entities – iterable of
DXFGraphicobjectsmapping – iterable of 2-tuples (entity_handle, sort_handle) or a handle mapping as dict.
