Oh good! The center of mass (centroid or first central moment) is also a graphically relevant construct, so we should think about that too! It’s easily scriptable for integrable curves (well, heck, I suppose they don’t even need to be integrable* do they?) but declarative access to the centroid would be good for realistic rotation (even sans gravity).

Yep, and the plan to enable this is for SVG2 to follow the combined SVG/CSS Transforms spec, where transform will become a property (instead of an attribute) and the transform-origin property will also be available. So in the future you'll be able to do: <g transform="scale(2)" transform-origin="50% 50%"> [Non-text portions of this message have been removed] ------------------------------------ ----- To unsubscribe send a message to: [email protected] -or- visit http://groups.yahoo.com/group/svg-developers and click "edit my membership" ----Yahoo!
