Hi Tanu,
Thanks for the reply.
To elaborate, we got a colourful map service which is being used as a Basemap in our JavaScript based application. We got a new scenario where Basemap need to be shown also in Greyscale. We are exploring the possible and probably the best ways to achieve this.
Time being, we created an additional Greyscale map service. But don’t want to maintain 2 map services.
Note: We are not looking for solutions based out of CSS based filters for browser.
Thank you
