I've been trying the GeoServer Rendering Transformations - Point Stacker. According to this docs there's an optional cellSize parameter for setting the "Size of the cells in which to aggregate points, in pixels, default = 1".
I made the SLD based on the SLD example in the above OpenGeo docs.
I tried 2 cellSize (30 and 150). Here are the results:
Blue squares are points (exact, not clustered). Orange circles are clusters. Both layers (blue squares & orange circles) are WMS.
There are 41 points in the island.
Now the question:The Graphic circles (defined in SLD as ) seems to be positioned incorrectly. The above pictures show that displacement grow with cellSize parameter.
Why does this happen? Please advise.
heaps of thanks.
