Apologies for not following up on the list, but the resolution to J's problem can be summarized as such (quoting ArcGISCache layer author, dmiddlecamp):<br><br>"Basically this problem crops up when ArcGIS is configured to serve
tiles for a fixed extent that is different from the full extent of
something like spherical mercator. The trick here is to set the actual
RestrictedExtent to the correct extent on your server, and make sure the
DPI of your tiles matches what OpenLayers expects (typically 72). Once
that is set, it changes how the map pans and zooms, and the layer
behaves normally.
<div><br></div><div>The jumping people experience is that ArcGIS
mis-represents the actual extent of all the features on the map. When
you're zoomed out, the server adds 'whitespace' to the edge which causes
confusion. As you zoom in this whitespace is reduced. Setting the
restricted extent prevents you from zooming / panning beyond the max
extent, and allows the layer to fix this problem. There may be other
ways to resolve this issue, but this fix worked for this situation."</div><br>Hope this helps,<br>Z<br><br><div class="gmail_quote">On Wed, Aug 24, 2011 at 3:56 AM, Bart van den Eijnden <span dir="ltr"><<a href="mailto:bartvde@osgis.nl">bartvde@osgis.nl</a>></span> wrote:<br>
