Hi all,
Because my GSoC student had no progress at the midterm evaluation deadline, I decided to fail him for GSoC. But since I was screaming so loud at LGM that this summer we would have a PowerStroke LPE, I couldn't escape coding it myself. Too bad, I should have applied for GSoC as a student myself...
For those interested: I think the PowerStroke LPE is ready for some playing and testing. You have to build Inkscape 0.48+devel with experimental LPEs enabled. [1]

Cusp nodes behave funny. To see clearly what happens, you have to apply a stroke to the path, and no fill. I do not yet know whether I am going to take the effort to properly handle cusp nodes... ;)
I know it is buggy, so please only mail *ideas* for improvement, etc.
thanks! Johan
[1] You have to build Inkscape with "#define LPE_ENABLE_TEST_EFFECTS", otherwise the LPE won't show in the LPE dialog. (uncommenting line 9 in src/live_effects/effect.cpp will do the trick)

Do you think some sort of presets library is possible? I'm talking about LivePen-like functionality.

Unfortunately the IP was acquired by FontLab who closed the project, so there is no "native" URL.

Hi,
I've played with the LPE a bit. It has potential. I have a few comments:
1. It would be nice if the end nodes were switchable to allow the end to be a straight line rather than folded (more calligraphic like).
2. I couldn't figure out how to add another control point. I see four in your screen shot.
3. It seems to me that this effect could be implemented as a special case of the pattern along path with a few changes:
Start with a rectangular pattern.
Display the pattern and control points along the path.
Adding a control point to the pattern adds a mirrored control point on the opposite side.
