Capture an area on the map
This example demonstrates how to take a snapshot of the map. It specifies area to be captured with top/left and bottom/right view port coordinates
Snapshot functionality belongs to the mapsjs-core module of the API.
The capture method of the H.Map class takes as an argument callback
function that is executed when snapshot is ready, instance of H.ui.UI class
to add the scale bar to the output, and top/left (50,50)-bottom/right (500,200) coordinates to specify the area of the map to capture.
