Hi Tav,

Given your input, I think we should have a new discussion on the topic during a conference you can attend.

Hello SVG,
The live path effect plus the original path (inkscape:original-d) are small compared to the eventual path which results.


I was a bit disappointed to see in the minutes that Skeleton Paths have
been thrown into a separate module with mesh transforms. Creating a
pattern-along-a-path is much simpler than any kind of mesh transform
could be, both for an SVG renderer and for someone creating content. I
am afraid that mesh transforms are unlikely to be implemented leaving
LPE's in the cold (especially with the talk of CSS Shaders).

The main advantage of handling LPE's in the browser is the ability to
animate them. I am told that Inkscape's implementation of
pattern-along-a-path is very quick. The path data is converted to an
"sbasis" notation, manipulated, and then converted back to SVG paths.
(This is much faster than doing direct manipulations on Bezier curves.)

Yes, one could create LPE's using JavaScript but that adds a high
entrance threshold for content creators.
