pinchZoom.scale; // scale
```
### Methods
Set the transform. All values are optional.
```js
pinchZoom.setTransform({
scale: 1,
x: 0,
y: 0,
// Fire a 'change' event if values are different to current values
allowChangeEvent: false,
});
```
Scale in/out of a particular point.
```js
pinchZoom.scaleTo(scale, {
// Transform origin. Can be a number, or string percent, eg "50%"
originX: 0,
originY: 0,
// Should the transform origin be relative to the container, or content?
relativeTo: 'content',
// Fire a 'change' event if values are different to current values
allowChangeEvent: false,
});
```
