DESCRIPTION
zoom scales and translates the window and the origin to cover the atom selection.
USAGE
zoom [ selection [,buffer [, state [, complete ]]]]
EXAMPLES
zoom zoom complete=1 zoom (chain A) 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:
