All, I'm using OpenLayers (latest trunk version) with GeoServer 2.0.1 to display various layers which have scale rules defined on them within the GeoServer SLD (i.e. MaxScaleDenominator and / or MinScaleDenominator).
I initially found that the scale in OpenLayers didn't match that in GeoServer but I have followed the steps outlined in this post http://openlayers.org/pipermail/users/2008-October/008453.html and as such added the following line before I use any of the OpenLayers classes: OpenLayers.DOTS_PER_INCH = 25.4 / 0.28; This means that the scale displayed by OpenLayers now matches that used by GeoServer to one / two decimal places. However, I have found that the map.zoomToScale function no longer works as expected. As such when I invoke map.zoomToScale(4578, false) the map zooms to a scale of 1:6800 instead of 4578 as expected. Does anybody have any ideas as to what I am doing wrong? Do I need to change something in addition to OpenLayers.DOTS_PER_INCH? Thanks Andrew
