Possible Feature - Slidable ROI functionality?

Hello,

I am new to GIS and am exploring the latest SDK for java (100.1.0). I am currently trying to display a ROI of a WMTS layer over a basemap. I am trying to achieve the effect of a sliding window, where only the portion of the layer in some region of interest (say a rectangle) is displayed, and the basemap is displayed anywhere outside of the ROI. Is there a way to achieve this with current api? If not will there be something like this added? The closest I found in previous versions was to use map overlays, though I can't find anything equivalent in current api. Any help or point to the right direction would be appreciated.

Thanks,

Natalie

Hi Natalie,

Hmmm. You may need to use 2 MapViews for this scenario. One on top of another. There isn't anything specific in the API to do this. Good use case, though!

Thank you Eric.

You're right, it seems two map views is the way to go. This approach works well. I was just wondering if there was an alternative method. Thanks again for the quick response.

Best regards,

Natalie
