How to enable the 'save' tool on a HV tilemap?

[sunny]

Hi,
I dealed with the same issue a while a go. As @philippjfr noted it’s due to browser security restrictions that it is not possible to save wmts tiles with the save tool. A manageable workaround is implementing a save option via file download.

Activating save option with WMTS Overlay

Sadly due to browser security restrictions (cross-origin policies to be precise) it is currently not possible to save WMTS tiles with the save tool and there does not appear to be a workaround here. The best you might be able to do is build a solution that saves the output server side using hv.save and then use a FileDownload button to trigger that and download it in the browser.
