Zoom

DESCRIPTION

zoom scales and translates the window and the origin to cover the atom selection.

USAGE

zoom [ selection [,buffer [, state [, complete ]]]]

EXAMPLES

# auto zoom depending on what's loaded in PyMOL
zoom

#
zoom complete=1

# zoom on just chain A
zoom (chain A)

# zoom on residue 142
zoom 142/

PYMOL API

 
cmd.zoom( string selection, float buffer=0.0,
          int state=0, int complete=0 )

NOTES

state = 0 (default) use all coordinate states
state = -1 use only coordinates for the current state
state > 0  use coordinates for a specific state

complete = 0 or 1:

Normally the zoom command tries to guess an optimal zoom level for visualization, balancing closeness against occasional clipping of atoms out of the field of view. You can change this behavior by setting the complete option to 1, which will guarantee that the atom positions for the entire selection will fit in the field of an orthoscopic view. To absolutely prevent clipping, you may also need to add a buffer (typically 2 A) to account for the perspective transformation and for graphical representations which extend beyond the atom coordinates.
