ExternalGraphic is a style property of a Point Symbolizer like the others, if you defined 2 rules depends on the scale it should work :

A little bit like this:

new OpenLayers.Rule({

maxScaleDenominator: 200000000,

minScaleDenominator: 100000000,

symbolizer: {

externalGraphic: 'a_img/travauxorange.png',

graphicHeight: 60*18/10 ,

graphicWidth: 65*18/10});

}),

new OpenLayers.Rule({

maxScaleDenominator: 100000000,

symbolizer: {

externalGraphic: 'a_img/travauxorange.png',

graphicHeight: 60*18/5 ,

graphicWidth: 65*18/5

}

})

HI Olivier,

yes I saw a lot of example like this one

http://www.geotribu.net/applications/tutoriaux/openlayers/style/style-attribut.html

they use OpenLayers.Style but are you sure than it's work with a external
graphic ?

I was thinking it's work just for an elementary symbol like circle polygon
and so on....

Best Regards

Christian
