Hi Devs, First of all, great work! It has been a pleasure to use the framework.
My app contains a vector based drilldown style map. United States (labels: 2 char state abbreviation) -> State (labels: 2 char county abbreviation) -> County (labels: 5 digit Zip code). The target browser is IE 7/8. While it renders fine on non-IE browsers, IE itself spends a significant amount of time drawing text according to the built-in profiling tool. I've tweaked the geometries to have max 2000 vertices but some levels contain over 200 features (extreme cases: 254 Texas counties, 282 Los Angeles zip codes). I was thinking of preventing the label from being drawn if it does not fit within the width of the geometry at the centroid for the current zoom. It seems like some time is spent rendering the VML textbox offline to determine the size. I would be fine with estimating the width from the number of characters since the label text characters are relatively equal width. VML rendering is beyond what my brain can wrap around so any suggestions of how I can tweak VML.js to do this? Thanks! -=Cliff -- View this message in context: http://n2.nabble.com/Need-ideas-for-VML-feature-text-label-rendering-speed-improvement-tp4866820p4866820.html Sent from the OpenLayers Dev mailing list archive at Nabble.com. _______________________________________________ Dev mailing list Dev@openlayers.org http://openlayers.org/mailman/listinfo/dev
