I'm using Expression Blend 2 August Preview to build path shapes. Those shapes are stored in path markup Data="M232, ..."
However, I'd like to animate (in C#) various points in the path geometry. I don't see anyway in the tool to convert the output from Stream to Path Geometry, nor do I see any library for doing the same. Before I go and write my own, does anyone know of a tool or method or converting a StreamGeometry into a PathGeometry? (either in XAML or code)...

I've written code to convert (created by the Blend editor)

That should let me name points and animate them. There are cases in the path markup mini-language I'm sure I'm not handling (the documentation isn't entirely clear), but if someone wants the code - it should be a decent starting place. Let me know...

hello.
well, since you've built it and can/want to share it with us, then please go ahead and send us a link to it ;)

I've got set up something so I can send a link. Anyone recommend a place I can do this - like a public developer blogging site?

Should you send me please the code to my email: yocheved@i-rox.net ?
