ROS2D.Zoom usage with ruler/grid for scale realization.
mouse wheel/scroll event ? I could utilize the pan view. However, the zoom is not working as I am not able to capture the mouse wheel event. both 'wheel' and 'mousewheel' event name tried with stage and canvas. I am able to capture other mouse events.
zoom ? In case the mouse wheel/scroll event is captured, how can I implement the startzoom(...) and zoom(...) methods. Any example.
ruler or grid ? After which I will need a ruler/grid alongside/on stage for scale realization as per zoom level.
map modify ? (to study about) On top of these, I will have to modify/annotate the static/dynamic map.
However, I am getting the mouse wheel event with the direct event adding to the document element. document.getElementById('map').addEventListener('wheel', ...);
Any implementation care so that pan and zoom do not interfere with each other.
Any direction towards these will help me achieve the mentioned goal.
