pyvista.ImageData.extent

property ImageData.extent: tuple

Return or set the extent of the ImageData.

The extent is simply the first and last indices for each of the three axes.

Examples

Create a ImageData and show its extent.

>>> import pyvista as pv
>>> grid = pv.ImageData(dimensions=(10, 10, 10))
>>> grid.extent
(0, 9, 0, 9, 0, 9)

>>> grid.extent = (2, 5, 2, 5, 2, 5)
>>> grid.extent
(2, 5, 2, 5, 2, 5)

Note how this also modifies the grid bounds and dimensions. Since we use default spacing of 1 here, the bounds match the extent exactly.

>>> grid.bounds
(2.0, 5.0, 2.0, 5.0, 2.0, 5.0)
>>> grid.dimensions
(4, 4, 4)
