<h2>Camera animations</h2>
|
|
<div style="width:700px; font-size:14px;">
|
|
You can move the view around programmatically using the .moveTo(options) function. The options supplied to this function can
|
|
also be (partially) supplied to the .zoomExtent() and .focusOnNode() methods. These are explained in the docs.
|
|
<br /><br/>
|
|
The buttons below take the fields from the table when they can. For instance, the "Animate with default settings." takes the position, scale and offset while using
|
|
the default animation values for duration and easing function. The focusOnNode takes everything except the position and the zoomExtent takes only the duration and easing function.
|
|
<br/><br/>
|
|
Here you can see a full description of the options you can supply to moveTo:
|
|

var moveToOptions = {

|
position: {x:x, y:x}, // position to animate to (Numbers)
|
|
scale: 1.0, // scale to animate to (Number)
|
|
offset: {x:x, y:y}, // offset from the center in DOM pixels (Numbers)
|
|
animation: { // animation object, can also be Boolean
|
|
duration: 1000, // animation duration in milliseconds (Number)
|
|
easingFunction: "easeInOutQuad" // Animation easing function, available are:
|
|
} // linear, easeInQuad, easeOutQuad, easeInOutQuad,
|
|
} // easeInCubic, easeOutCubic, easeInOutCubic,
|
|
// easeInQuart, easeOutQuart, easeInOutQuart,
|
