# Examples from pyvista.ImageDataFilters.image_dilate_erode
# =========================================================

# Demonstrate image dilate/erode on an example dataset. First, plot
# the example dataset with the active scalars.
from pyvista import examples
uni = examples.load_uniform()
uni.plot()

# Now, plot the image threshold with `threshold=[400, 600]`. Note how
# values within the threshold are 1 and outside are 0.
ithresh = uni.image_threshold([400, 600])
ithresh.plot()

# Note how there is a hole in the thresholded image. Apply a closing
# filter with a large kernel to fill that hole in.
iclosed = ithresh.close(kernel_size=[5, 5, 5])
iclosed.plot()
