# Examples from pyvista.ImageData
# ===============================

# Create an empty ImageData.
import pyvista as pv
grid = pv.ImageData()

# Initialize from a vtkImageData object.
import vtk
vtkgrid = vtk.vtkImageData()
grid = pv.ImageData(vtkgrid)

# Initialize using just the grid dimensions and default
# spacing and origin. These must be keyword arguments.
grid = pv.ImageData(dimensions=(10, 10, 10))

# Initialize using dimensions and spacing.
grid = pv.ImageData(
    dimensions=(10, 10, 10),
    spacing=(2, 1, 5),
)

# Initialize using dimensions, spacing, and an origin.
grid = pv.ImageData(
    dimensions=(10, 10, 10),
    spacing=(2, 1, 5),
    origin=(10, 35, 50),
)

# Initialize from another ImageData.
grid = pv.ImageData(
    dimensions=(10, 10, 10),
    spacing=(2, 1, 5),
    origin=(10, 35, 50),
)
grid_from_grid = pv.ImageData(grid)
