The GEOMETRY parameter currently only applies to the WMS and WCS services. Any chance that it can can be implemented for the GetTile request of the WMTS as well?
I was wrong afterall, the WMTS masking does work with a GEOMETRY parameter applied for clipping the layer, as long as the FORMAT is set to “image/png” and TRANSPARENT=TRUE.
Sorry for not responding earlier. I think this functionality was not available then yet, we have added it for WMTS in one of the recent releases. And forgot to respond to this post…
Thank you for a follow-up.
