Hi Rob, I've started work on translating your Multifill script to a C plugin. The code has finally become intelligible to me, after I read a basic Scheme tutorial. It's all about lists!

Anyway, as a start I managed to convert the simpler Flatten procedure. Result was no discernible speed-up. I didn't really expect to see much speed-up on a while loop that doesn't run many times.

Oh well, now to see if I can translate the more complex Multifill procedure.

Thanks for the rep whacking

What do I need to be able to compile gimp plugins (written in C) on WinXP? You mentioned MinGW/MSYS. Anything else?

Superb work. Thanks very much. I will put it all together in a zip file with a readme and release it to the GIMP plugin registry, and also announce it in the Mapping Elements forum of this web site.

Here's a preview (linear taper for now):

Need to add a dialog window with taper options.

OK thanks. Problem is turning out much more difficult than I first thought.

Sorry to keep annoying you, but I had an idea for making a better-looking tapered stroke. No offence intended, but your tapered path script produces aliasing effects which can be ugly depending on the brush sizes chosen. Instead of using brushes of different sizes like you have in your script, my idea is to create the outline of the tapered path (by transforming the original path), convert it to a selection, and then fill with foreground color. I think this may avoid ugly aliasing effects, but I'm not sure; only way to be sure is to try it out.

So here I am spamming you and criticising your work (sorry, sorry), but would you have a problem if I created and released such a plugin? I was thinking of using the name "Stroke Path with Taper", so it wouldn't be too easily confused with your "Tapered Stroke Path". I don't want to steal your thunder, so to speak, so let me know what you think.

Alright I'm done, I hope there's no major bugs: Download.

I've read that it's a pain to compile GIMP plugins on Windows, but if you can do it that would be great.

Meanwhile, I've decided to add an option to allow users to preserve sharp corners (e.g. which allows them to draw things like crescent moons). So I'm still working on the dialog for that.

Once I'm finished I'll send you a link to my source code so you can try to compile it. Then I'll release the plugin to an unsuspecting public.

I fixed the undo problem. For some reason I can't add the plugin to <Vectors> (i.e. where you put your Fractalize Path script), so I put it in <Image>/Edit, same place as your Tapered Stroke script. Do you know of anyone who can compile these plugins on Windows? I'm pretty much ready to release but I'll wait if someone wants to compile for Windows.

Here's a crazy image I created in a couple of minutes with my plugin:
