path-to-shape: the hidden son of Gfig and shape-paths

Possibly worth a mention that the path does not have to be continuous. You can merge (or link) a couple of paths together before applying the plug-in.

Ooh, this is snazzy! I can't wait to try this out. Thanks, ofnuts!

Another great plugin. :jumpclap

Thank you for longer - and ask for more ?
Is it possible that add heart and epicycloid ?

Thank you, ofnuts!
Will be playing a lot with this.

For the cycloid, see my path-waves plugin.

For the heart, will think about it

It is totally irrelevant to this script but how do you add anchor point to a path (Bezier curve
or straight line) right in the segment's center? Is there a script of yours that can do that, divide a path into power of 2 number of segments?
E.g. we have a straight line between two anchor points, apply the script = 2 equal segments, reapply the script = 4 segments and so on.

Not very difficult, but none of my script does that so far. I can put that on my bucket list

Please, do.

I was trying to make concentric circles with path-to-shape's 'circle from radius'
where radii would be nx2, then realized, there is no precise way to do it in gimp. Now I can think of a few more cases
where I would need such a script. Thank you ofnuts!

Hmm. What you need is a way to split a line into N segments. So you would do something like:

And then the script would evenly spread the nodes:

does your generate intermediate paths not do something similar?

True

No, I was talking about a script that would find a center on pre-existing/imported path (linear or curved) and place an anchor there.
To create such a path from scratch I don't need a script, I'd probably do just fine using guides, grids and rulers.
The script would have a more general purpose than just creating a number of concentric circles.

Besides, I don't see how intermediate paths plugin would do the task for the curves, e.g. an arc.

ofnuts, please, tell us how to make the "CircleOnDiameterOverRegularPolygon."

False.

A new beauty concept to create paths.
I appreciate the path-waves - but your new approach to creating paths is completely different (I thought of a few points create Cykloid)

- Make a regular polygon (any of three methods)
- Right-click polygon path -> Shapes>Circle>Circle from diameter

So that begs the two questions:

1) How does one approximates a cycloid with Bezier splines, and 2) what are the point you would have in mind?

Is it possible this way?

Thanks, ofnuts.

ofnuts, that's the result after your explanation. I did a little modification. Thanks again.
