napari-animation can also be run headless, allowing for reproducible, scripted creation of animations.

from napari_animation import Animation

animation = Animation(viewer)

viewer.dims.ndisplay = 3
viewer.camera.angles = (0.0, 0.0, 90.0)
animation.capture_keyframe()
viewer.camera.zoom = 2.4
animation.capture_keyframe()
viewer.camera.angles = (-7.0, 15.7, 62.4)
animation.capture_keyframe(steps=60)
viewer.camera.angles = (2.0, -24.4, -36.7)
animation.capture_keyframe(steps=60)
viewer.reset_view()
viewer.camera.angles = (0.0, 0.0, 90.0)
animation.capture_keyframe()
animation.animate('demo.mov', canvas_only=False)
