sap.m.UploadCollection - get Base64 Image

Hi there,

I am using the Object sap.m.UploadCollection to take pictures from my mobile device (I dont want to use cordova to do this).

Cordova has a nice method, which gives me the base64 string to work with it (e.g. draw into canvas, add to carousel etc).

is there a method for sap.m.uploadcollection which gives me the base64 string of the uploaded image without uploading it to any server?

I dont really understand how uploading to a server works there..

Thanks!
