Vertigo BigPicture (aka Hard Rock?) sample code

Vertigo has published their BigPicture code on codeplex. As of this time, only the mouse handler code is available but hopefully this will change. The mouse handler code is clean and well documented though so I am going to use it on my project.

One of the known issues with MultiScaleImages is that it doesn't properly handle relative URI in the Source property. Vertigo has found a neat workaround by converting a relative Uri to an absolute Uri using the Uri.TryCreate method

// Directly lifted from http://www.codeplex.com/BigPicture
Uri collectionUri;

if (Uri.TryCreate(App.Current.Host.Source, "/Collection/items.bin", out collectionUri))
    image.Source = collectionUri;
