How to take screenshot of map in CesiumJS?

Question

I'm using CesuimJS (http://cesiumjs.org/) to present map. I want to take a screenshot of part of the map.

I tried using Three.js (http://learningthreejs.com/blog/2011/09/03/screenshot-in-javascript/) but failed to take a screenshot

Any ideas?

Answer 1

There is no need to use ThreeJS.

You can use the canvas function toDataUrl.

viewer.render();
viewer.canvas.toDataUrl();

toDataUrl returns url that can be used to get the screenshot.
