We have a requirement to take the snapshot with the marker and then upload it to the server which is independent of wikitude tools. I am able to take the snapshot but unable to post it as cordova plugins are not available at AR view. Kindly help me in this regard with some sample code.
You should be able to define a path inside the application bundle that is used by the Wikitude SDK to store the screenshot to. I'm sure that there is a Cordova plugin that you can use to access this file and e.g. upload it to a server. To get the path to the Cordova application, please refer to our examples that explain how to communicate between Architect & Cordova. It's also documented in our Cordova Getting Started Guide under the topic `Adding communication between Cordova and Architect`.
