pyXenium.contour.expand_contours

expand_contours(sdata, *, contour_key, distance, mode='overlap', output_key=None, copy=False, voronoi_sample_step=None)

Expand an existing contour layer into a derived contour layer.

Parameters

sdata

Input XeniumSlide container.

contour_key

Source contour key inside sdata.shapes.

distance

Positive outward expansion distance in the contour coordinate units.

mode

Either "overlap" for ordinary buffering or "voronoi" for mutually-exclusive Voronoi partitioning over the buffered support.

output_key

Target contour key. Defaults to f"{contour_key}_expanded".

copy

When True, return a copied XeniumSlide. Otherwise mutate sdata in place.

voronoi_sample_step

Maximum segment length used to sample boundary seed points in Voronoi mode.

Parameters:

• sdata (XeniumSlide)

• contour_key (str)

• distance (float)

• mode (str)

• output_key (str | None)

• copy (bool)

• voronoi_sample_step (float | None)

Return type:

XeniumSlide | None
