Hi all, well i guess this primarly goes to Eric but anyone can jump in :)
Ive just tried gridStrategy from vector-behavior http://dev.openlayers.org/sandbox/vector-behavior/ and im pretty happy how it works. So i just want to drop few lines while impressions are still fresh. i know its still in develop. so maybe thats the answear to some of my questions ;) First improvment one can see beetwen strategies Grid & BBOX is the similar one to WMS & WMS.Untiled. When you drag the map, features dont dissapear but only new ones load. Very very nice! But when you observe XHR traffic, there are much more requests, cuz it splits big request to 256x256 tiled requests. First thing i did is to set option tileSize: new OpenLayers.Size(512,512) and I got satisfing number of 4-8 request per map move. As i used only points features i put options safe: false. 1)First question, setting tile size different then map is perfectly ok, right? Doesnt affect anythign else then Grid strategy? Few words about buffer option: Setting buffer to lets say 2, i could see that there are much more requests, and inside strategy-grid-grid object i can see that there are many more objects (tiles). But when i move my map just for 20px, new requests are being issued 2) Shouldnt I have at least 512px (tile size) before new requests are made? And one more question, featuresadded event is triggered for every tile loaded, thus it makes it little bit harder to see when all the features are loaded. What would be the right way to do it? I just saw that inside Grid.js /* FIXME addTileMonitoringHooks: function(tile) { that should answear my question. Any tickets for that issue maybe? That would be all from me, for now :) Thank you PS http://dev.openlayers.org/sandbox/vector-behavior/examples/strategy-grid.html gives error: this.format is null [Break on this error] return this.format.read(doc); ...and i also have one bug, but ill just write it aside, and ask it later to keep email smaller :) Cheers -- Ivan Grcic _______________________________________________ Dev mailing list Dev@openlayers.org http://openlayers.org/mailman/listinfo/dev
