zoom-in and zoom-out buttons #597

Open zhangzhen opened 2 years ago

How can I implement zooming using zoom-out and zoom-in buttons rather than using mouse scrolling?

I think a combination of using hgRef.current.getLocation() and gosRef.current.zoomTo() can allow implementing zoom in and out buttons.

One thing we can support in the API is something like zoomIn() and zoomOut() somewhere at https://github.com/gosling-lang/gosling.js/blob/73061be167c058a4fb18ef5dec00c87ff2d5af38/src/core/api.ts#L130
