Silverlight 2 and Opera

To make the previous example also work on Opera I would have to

  • Set the data on the object to be "data:application/x-silverlight-2," to get it to work at all
  • to restore the effect of transparency remove the <param name="windowless" value="true" />
  • set an opaque value rather than <param name="background" value="#00000000" /> matching the page background colour
  • manually tile a matching background image and set background image brush with Stretch="None" to match any page background image

In particular, there seems to be no obvious way to get at the parameter set of the object from JavaScript via a DOM look-up on the <object> tag, otherwise I would have done some jQuery magic via browser sniffing instead.

Bug in my jQuery usage. BRB

You can do something like

but once you've tiled with an opaque image, there's no effect (even if this substitution were in fact in time to be useful).

Sample here.

I guess such customization would be possible via the silverlight.js file; however that needs tome work of its own to fix up to provise silverlight 2 data types.
