All,<br><br>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).<br>
<br>I initially found that the scale in OpenLayers didn't match that in GeoServer but I have followed the steps outlined in this post <a href="http://openlayers.org/pipermail/users/2008-October/008453.html">http://openlayers.org/pipermail/users/2008-October/008453.html</a> and as such added the following line before I use any of the OpenLayers classes:<br>
<div style="margin-left: 40px;"><br>OpenLayers.DOTS_PER_INCH = 25.4 / 0.28;<br></div><br>This means that the scale displayed by OpenLayers now matches that used by GeoServer to one / two decimal places.<br><br>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.<br>
<br>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?<br><br>Thanks<br><br>Andrew<br><br>
