Exponential Growth?

[jediguitar101@yahoo.com]

Is there a way to grow a line/segment (one with curves) exponentially? Thus, sharp/pointed at one end and fat at the other?

To get a smooth line, usually best to create the line as a path. (unless you are using a graphics tablet)

Then stroke the path, Edit -> Stroke Path, using a brush dynamic. Depends on path direction. Ofnuts has a plugin (ofn-path-edits) to reverse direction. see: http://sourceforge.net/projects/gimp-pat...s/scripts/    

   

Have to confess, not always obvious how to make your own dynamic. 

see: https://docs.gimp.org/en/gimp-tool-dynamics.html

Edit:
Still using paths, but an old (ancient) compiled plugin, but it does have an exponent option. Pulled out of my archive.
I do not know which OS you are using so both linux and Windows versions, use the the appropriate. Sorry if you are a Mac user.  Looks like this:

   

Tried with Gimp 2.10.32 / kubuntu 20.04 / Win 10 and it still works. Unzip and put in your plugins folder. Registers in the Edit Menu

@rich2005 ...that's exactly what I was after! Thank you VERY much. I'll give this a whirl. Thank you for the plugin as well

RobA has a script that could be an option:
--➤ tapered_stroke_along_path

Have you tried this ? 2008 Really for Gimp 2.6, sort of works with Gimp 2.8 but not Gimp 2.10

I haven't actually tested it.
I happened to come across it while browsing the web.

On the other hand, I found a nice plugin by the same author (RobA) from 2009 - Subterranean Map Prettier, which is working on Gimp 2.10.

So I thought it would be possible that this Tapered Stroke Path plugin could also be ok with Gimp2.10.
