Thanks Andrea, It is a mad concept to try and implement - but I expect users will love it as it is more inuitive than the use of feature type style to control z-order.
Feedback (i.e. suggestions feel free to say no)... *Single layer z-ordering* For the sorting within a feature type style change - can we represent that explicitly as a SortBy object (the vendor-option only has to be used for the XML representation right?). This would make easier (and more object oriented) for java developers ... The rest of the workflow/tradeoffs here makes sense and you have explained it very clearly. *Cross layer z-ordering* For point 2 changing from the painter model - which seems to be the difficult part. Is it possible to review the data and process the style into the painter model? Would require some kind of histogram of the data in question, and would only work in a few narrow cases I guess ... Is it possible to break out a new StreamingRenderer (or subclass) in order to avoid making streaming renderer more complicated. guess this is an implementation detail and not really the subject of the proposal. The sortByGroup makes sense, and thanks for noting the CSS representation of this stuff. aside: I hurt my head trying to picture the interaction between this idea and the composite / composite base vendor extension. *Timeframe* Given that we are nearing the code freeze I wanted to check if this proposal is a race before August 18th? -- Jody Garnett On 3 August 2015 at 05:48, Andrea Aime <[email protected]> wrote: > Hi, > as already anticipated during the bi-weekly meetings, here > is the proposal for single and cross layer z-ordering in map rendering: > > > https://github.com/geotools/geotools/wiki/Z-order-control-during-map-production > > The proposal might not have been needed, there are no API changes, but > the change is large enough that I wanted to float it to the PMC anyways > > Cheers > Andrea > > -- > == > GeoServer Professional Services from the experts!
