There you go: Use: document.body.style.zoom=1.0;this.blur(); 1.0 means 100% 150% would be 1.5 1000% would be 10.0 this.blur() means that the curser, maybe you selected an input field, looses focus of every select item. or: You can use the css3 element zoom (Source) Firefox does not allow zooming with the browser because you can’t access the … Read more
In order to do this, you would need to fix the user’s viewport so that they cannot pinch zoom the page, and then use a touch events library like Hammer.js to attach a callback to the pinch zoom gesture that appropriately resizes the element on the page you’d like to scale. viewport fixing happens in … Read more
NVD3 is a very cool project that has a number of reusable charts written upon D3. See here for an example of a line chart with a view finder, along with source code. Update: The NVD3 example now also links to an example of Mike Bostock’s (creator of D3) which demonstrates similar functionality, the ability … Read more
There are many possible camera positions + orientations where the bounding box would fit inside the view frustum. But any procedure would select one specific camera position and orientation. If you would consider bounding spheres, one solution could be to first change orientation to look at bounding sphere center then move back sufficiently (negative look … Read more

Inside the function you may also access cluster.getCenter(); cluster.getMarkers(); cluster.getSize(); I use this to switch to a different map type, as I … Read more
You can simulate zooming in and out by scaling the root activity view. Here’s some starter code: View v = findViewById(android.R.id.content); // get reference to root activity view v.setOnClickListener(new OnClickListener() { float zoomFactor = 1.5f; boolean zoomedOut = false; @Override public void onClick(View v) { if(zoomedOut) { // now zoom in v.setScaleX(1); v.setScaleY(1); zoomedOut = … Read more
