Camera & controls

Use these helpers to focus the view and control the on-canvas UI.

Zoom to a selection

import molsysviewer as viewer

view = viewer.MolSysView()
view.load("1CRN")
view.show()

view.zoom("protein", duration_ms="250 ms", extra_radius="4 angstroms")

Reset the camera

view.reset_camera()

Save and restore a camera view

snap = view.get_camera_snapshot()
view.set_camera_snapshot(snap)

# Pretty-print the snapshot (for notes or config files)
print(view.get_camera_snapshot(pretty=True))

Show/hide the on-canvas controls

view.set_controls_visible(True, autohide=True)
view.set_controls_visible(False)
