Calculate size of entities in pixels

[levinsy]

Hi,

Is it possible to get the size in pixels of entities in a drawing as if they were projected on a screen when using the js api?
More precisely what I'm trying to achieve is to zoom an RBox on the entire view port and then calculate its pixel size and the pixel size of all of the entities contained inside that RBox.


Thanks,
Yair

You can convert between vector measurements and screen measurements (pixels) using the map functions in RGraphicsView (mapToView, mapDistanceToView, mapFromView, mapDistanceFromView).
