Salve Andrea,
Thanks for the input, I will read the info send by Ben in order to add this
new +1 parameter to repository.
*More Info*
I have read the idea behind the cellsize and the actual cluster position.
Having this parameter set on *true*, the issue with with crossing the grid
can be mitigated with the cellSize and (min|max)zoomdenimination (in my
particular case under a certain zoom the points are shown at their true
location).
The gain in having this parameter is that the cluster is positioned inside
the area where points are located (see use-case-1.jpg and
use-case-desired.jpg).
*Behind the scene*
Some developers may want this behavior in order to have an alternative to
OpenLayers's clusterization strategy. I had some issues with 13.000 points
to be clustered at the client side. The browser memory spiked to 3-400 MB.
Having this option can alleviate the memory foot print on the client side
not to mention issues regarding mobile's app development.
*On a side note:*
- I do have some plans to add more parameters to point stacker.
- I have seen that if you treat it as* tiled layer* some weird artifacts
appear. I will investigate further.
Have a nice day.
