copied!<p>It is probably a roundabout way of going about it, but you might find some useful stuff in the javascript and XAML from <a href="http://www.silverlightearth.com/" rel="noreferrer">SilverlightEarth.com</a> which a Silverlight 1.0-based map-tile-client. It can load VE, Google, Yahoo (there is a <a href="http://www.silverlightearth.com/2/" rel="noreferrer">DeepZoom version</a> that can load OpenStreetMap, Moon and Mars too; but since it uses MSI it doesn't really help on the WPF 3/3.5 front).</p> <p>Although the javascript is a little untidy, you can clearly see it is creating a Silverlight 1.0 Xaml (dynamically sized) Canvas, filling it with tiles (Image controls) and handling zoom in/out and pan requests. You would need to make sense of all the javascript and convert it to C# - the XAML should mostly come into WPF unaltered. I have <a href="http://conceptdev.blogspot.com/2008/03/deepzoom-in-silverlight-10.html" rel="noreferrer">tested this Silverlight 1.0 with a Deep Zoom tile pyramid</a> (and <a href="http://conceptdev.blogspot.com/2008/03/deepzoom-in-silverlight-10-part-deux.html" rel="noreferrer">here</a>) so the concepts are applicable (ie. not just for maps).</p> <p>I know this works because I have done it myself to build the map viewer in <a href="http://geoquery2008.com/" rel="noreferrer">Geoquery2008.com</a> (<a href="http://geoquery2008.com/screenshots/072_Across180a.png" rel="noreferrer">screenshot</a>) which is WPF/c#. Unfortunately the Geoquery2008 assemblies are obfuscated, but you might still glean some ideas or useful code via DASM/Reflector. It is still a beta so I wouldn't claim it is 100% done. I hadn't really thought of factoring out the map code into a separate control but may I will look into that if another one doesn't appear...</p> <p>Incidentally I also started off with the ScrollViewer, but am planning to ditch it and mimic the javascript more closely so it's easier to re-use Image objects when panning/zooming (by gaining more control over the process than ScrollViewer provides).</p> <p>These MSDN pages on the <a href="http://msdn.microsoft.com/en-us/library/bb259689.aspx" rel="noreferrer">Virtual Earth tile system</a> and the <a href="http://msdn.microsoft.com/en-us/library/cc645077(VS.95).aspx" rel="noreferrer">Deep Zoom file format</a> and related links is probably also a useful reference.</p> <p>Finally - I guess you've seen since this post that DeepZoom/MultiScaleImage is likely to be in <a href="http://www.ddj.com/windows/211601295" rel="noreferrer">.NET 4.0/Studio 2010</a>.</p>
