pyvista.ImageData.spacing

property ImageData.spacing: tuple[float, float, float]

Return or set the spacing for each axial direction.

Notes

Spacing must be non-negative. While VTK accepts negative spacing, this results in unexpected behavior. See: pyvista/pyvista#1967

Examples

Create a 5 x 5 x 5 uniform grid.

>>> import pyvista as pv
>>> grid = pv.ImageData(dimensions=(5, 5, 5))
>>> grid.spacing
(1.0, 1.0, 1.0)
>>> grid.plot(show_edges=True)
