zoomtool zoomtool(1) zoomtool(1,option) zoomtool(N,<property1>,<value1>,<property2>,<value2>,...) zoomtool('set',hax,<property1>,<value1>,<property2>,<value2>) zoomtool(hax,arg1,arg2,...) is equivalent to : zoomtool(arg1,arg2,...'axes',hax)
Install Modelit zoomtool.
| N | any | mode of operation, available values:
1 install zoom utility (default)
2 zoom in using rbbox
3 zoom back using history of zoom windows
3.1 Maximise X&Y
3.2 Maximise X
3.3 Maximise Y
4 clear zoom history
5 add current zoomwindow to menu
6 toggle sliders on/off
7 delete stored zoomwindows
8 temporaly disable zoom buttond
9 reinstall zoom buttond
10 zoom out (in this case axis&factor are supplied with arg2&arg3)
11 zoom to predefined values
Example: zoomtool(11,'axes',hax,'xlim',xlim,'ylim',ylim)
12 execute callback of x slider
13 execute callback of y slider
14 set up X movie
16 force execution of synchronisation callback
17 pretend current view is result of zoom action (enables undo,
xsync, ysync, scale, move, etc)
18 return zoomhandle
19 change view so that specific hg object fit
20 center view on selected objects, do not resize

| option | any | Structure with name/value pairs (or specify name value pairs as
seperate arguments). Specific zoom settings
opt.axes:
handle van zoom axes
opt.parent:
uses 'axes' or 'window'(default: axes)
axes: install buttondown on axes
window: install windowbuttondown on figure
opt.xsync:
handles of synchronized x-axes
opt.ysync:
handles of synchronized y_axes
opt.patchsync:
handle of patch object (usually in overview map)
opt.scale:
string containing name of function to call after scaling
coordinates.
(will also be added to windowresize function)
WARNING: opt.scale installs a resize function on
top of current resize function. when axes is
deleted this resize function is not disabled
This function is typically used to recompute xdata and
ydata values of points that must be plotted a few pixels
apart from a specific position.
opt.prescale
similar to scale but called before syncing the current
axes with other axes' as specified in xsync and ysync.
This is typically needed if xlim/ylim are changed, as is
the case with MapViewer
opt.move:
string containing name of function to call after shifting
coordinates
============
When ZOOMING on axes : first call opt.move, then call opt.scale
When RESIZE on window: only call opt.scale
When MOVE on axes : only call opt.move
============
See also "zoomtool/exitaction"
Typical signature of call:
opt.move([],ISSCALE,arg1,arg2,...), where ISSCALE is
set to true if a call to scale function will follow
shortlty. if "move" and "scale" do overlapping
actions it is a good policy to use argument ISSCALE
for early cancelling of move action.
opt.shiftclick:
function that is called after shift+click (windows)
example: opt.shiftclick='rbrect_init(1,0,''line'');'
opt.dblclick:
function called when doubleclicked in axes
opt.leftclick:
"leftclick" mean clicking in a normal way (left mouse
button) without movement of te mouse.
specify function (hint: to prevent zooming at left
mouseclick specify ' ')
opt.xmovie:
set to 'on' if Xmovie capability is needed (default: 'off')
opt.label:
Label van hoofd menu (default: Zoom)
opt.visible:
Label voor zoom 'on' or 'off'
opt.fa_zoom:
if 1: keep fixed aspect ratio
opt.keypress:
if 1: enable zooming by key press (this will
overwite keypress function for current window)
opt.wheel:
if 0: disable mousewheel while zooming
if 1: enable mousewheel zooming (standard mode)
if <1: enable mousewheel zooming (slow)
if >1: enable mousewheel zooming (fast)
opt.interactive:
if false: disable interaction with the mousewheel, keys and mouse
if true: enable interaction with the mousewheel, keys and mouse
opt.xrange:
zoom range (x-axis)
opt.yrange:
zoom range (y-axis)
