[OpenLayers-Users] Different renderIntents when features have different styles?

[Jeff Dege]

My problem is that I can only apply a StyleMap to a layer, and I need a different appearance for each feature.

It looks, though, as if using a parameterized StyleMap, as the example shows, should work.  

I can the same StyleMap for all features, but have individual settings within it (strokecolor, fillcolor, etc.) determined by attributes on each feature.

Thanks.

Hi,

If feature.style is set, it will always take precedence over layer styles. To achieve what you want, create a stylemap with a "default"
and a "select" renderIntent. See
http://openlayers.org/dev/examples/styles-rotation.html for an example that does this.
