Today I updated the Deep Zoom demo I originally published a few months ago for the RTW release of Silverlight 2. The new version shows how to do mouseovers on the individual subimages in a Deep Zoom scene—something that wasn’t at all obvious to me how to do until I read Jaime Rodriguez’s excellent blog post explaining that the order of the subimages in the MultiScaleImage control’s SubImages collection mirrors the indexes in Metadata.xml. When the cursor enters a subimage in the revised demo, a caption identifying the location depicted in the image appears at the top of the page.
I’ll post the source code for the sample once I figure out how to decrease its compressed size of 373 MB. I suppose I’ll have to post the project without the images, but that somehow seems to defeat the purpose.
