Zoom in on web browser

Hello everybody.

I’ve a requirement where I need to run a test case on a web browser, but I need to make a zoom in on a image.
i’ve the follow code
public void Acercar(def params){

    MultiTouchAction multiTouch = new MultiTouchAction(Driver.driver);
    MobileElement element = (MobileElement) Elementos.find(params, Driver.driver
	int y = element.getCenter().getY();
	int x = element.getCenter().getX();
    TouchAction action0 = new TouchAction(Driver.driver).press(x-10, y-10).moveTo(x-20, y-20).release();
    TouchAction action1 = new TouchAction(Driver.driver).press(x+10, y+10).moveTo(x+20, y+20).release();

but when the test case tries to run it, it’s crash and say:

Method has not yet been implemented (WARNING: The server did not provide any stacktrace information) Command duration or timeout: 5 milliseconds Build info: version: ‘3.4.0’, revision: ‘unknown’, time: ‘unknown’ System info: host: …

Also, I tried differents solutions like
driver.executeScript('mobile: pinch', {'id': element, 'scale': '0.5', 'velocity': 1});

but any works.

how I can do zoom on a web browser !
