Canvas size

This notebook sets a fixed canvas width and height to ensure that all generated images are reproducible, regardless of the notebook’s display size.

This notebook mirrors the fixed size NiiVue notebook

from ipyniivue import NiiVue
from IPython.display import display

# ---- constants ----
NV_WIDTH  = 256   # pixels
NV_HEIGHT = 1024  # pixels

# ---- widget setup ----
nv = NiiVue(height=NV_HEIGHT)
nv.load_volumes([{'path': '../images/mni152.nii.gz'}])

# ---- layout using constants ----
