set_geom_precision
Set the precision of a Shapely geometry.
Note
Typically six decimals is sufficient for most applications.
Parameters:
Name | Type | Description | Default |
---|---|---|---|
geom
|
BaseGeometry
|
Input Shapely geometry. |
required |
precision
|
int
|
The number of decimal places to round the coordinates to. |
6

Returns:
Name | Type | Description |
---|---|---|
BaseGeometry |
BaseGeometry
|
The input geometry with coordinates rounded to the specified precision. |
Examples:
>>> from histolytics.utils.gdf import gdf_apply, set_geom_precision
>>> from histolytics.data import hgsc_cancer_nuclei
>>> from functools import partial
>>> # Set precision to 3 decimal places
>>> prec = partial(set_geom_precision, precision=3)
>>> gdf = hgsc_cancer_nuclei()
>>> gdf = gdf_apply(gdf, prec, columns=["geometry"])
>>> print(gdf.head(3))
