topojson.core.cut¶

Cut ¶

Bases: Join

This class targets the following objectives: 1. Split linestrings given the junctions of shared paths 2. Identifies indexes of linestrings that are duplicates

The cut function is the third step in the topology computation. The following sequence is adopted: 1. extract 2. join 3. cut 4. dedup 5. hashmap

Returns:

Type	Description
`dict`	Output of `Join` with the lines cut (`linestrings`) and the keys `bookkeeping_duplicates` and `bookkeeping_linestrings`

to_dict ¶

to_dict()

Convert the Cut object to a dictionary.

to_svg ¶

to_svg(separate=False, include_junctions=False)

Display the linestrings and junctions as SVG.

Parameters:

Name	Type	Description	Default
`separate`	`boolean`	If `True`, each of the linestrings will be displayed separately. Default is `False`	`False`
`include_junctions`	`boolean`	If `True`, the detected junctions will be displayed as well. Default is `False`	`False`
