Dear Support,

I’m trying to use the mouse Events raised by the WebViewer in order to add some annotations into my document.  
Code below is working excepted that there is a shift between the position of my freeText and the mouse coordinates…  
How could I do to make the position of the annotation match with the position of my mouse cursor when there is a mouseUp Event.

Many Thanks in advance for your kind support
