Powerstroke cusps
Hi all, I've been working on cusps on powerstroked paths. And I've obtained a first success. The attached picture shows a comparison between how powerstroke strokes thick cusps, and how Inkscape does it normally (I suppose according to SVG spec). I think the powerstroke solution is more artistically pleasing, what do you think? :-)
Cheers, Johan

Not a big fan of your pointy cusp, sorry. It looks overdone, at least for the style of work I tend to do (which is more technical, less artistic...)

Your solution looks better for my point of view because Inkscape solution shows visual discontinuities (an optical illusion?)

At first I didn't like it so much... but the longer I stared at it the more I liked it. I don't think it would work for all styles and what happens at small angles? Will the point get too long?

The way it works is quite simple and hopefully intuitive. See attachment.
Ciao, Johan
I think it looks really awesome from an artistic perspective. I tend to view LPEs as either technical or as artistic honestly, so I have no problem (personally) if it's just how powerstroke works.
Cheers, Josh

I like LPE! A lot!
Cusps like these are a delight in typography and graphic work and usually have to be outlined by hand. On the other hand, I understand Rob, too, since these cusps 'cheat a little' to provide a nice optical effect and might not resonate in technical applications. Is it possible to have both?
... Looking at the nice explanation you submitted, the mirror axis is perpendicular to the tangent, right? How would mirroring come out on the middle point on a curve like this: { (a curly brace)? (I am imagining something, and think it would look very lovely, and provide unique miter, but I might be wrong, as usual)

My explanation of how it works is not quite the way it works... The curly brace curve will appear with a beveled cusp.
I just committed the SVG miter cusp type. I've named the smoother cusp type: "Extrapolated", as it extrapolates the curve to obtain the cusp shape.

See attachment. I've added the normal SVG miter, but... come on... you *must* like the extrapolated one!

OK - I will agree these look pretty darn nice ;)
I believe the variation I found too long was when two convex curves came together at an acute angle. This can make the extrapolated cusp very long.

I added a miter limit setting (like SVG has). If the miter would be too big, the join will be beveled.
