Nowadays, I draw (and save) my own path with Gimp's Path Tool and use something nearer the opposite of a bluezillion; I never go over a few dozen points. Then I then dupe the path and reposition the nodes away from the originals, trying to anticipate the directions which will result in the smoothest transitions in PB.

@GraMP
Thank you for putting that in!
[I had already forGOT how I do it... Still you might have pointed out that, even though there are fewer path nodes, you, er we, still have to adjust the handles for the right curve. (Or do we, er me/I/us? Hmmm....)]

RobA - I have been trying to install mathmap on gimp 2.8.10 running on unbuntu 12.04, I have been using the terminal to help identify errors in loading Mathmap.

One particular error kept coming up

(gimp:4475): LibGimpBase-WARNING **: gimp: gimp_wire_read(): error
RMA-path-blend: image-type contains unrecognizable parts:'RGB*, GREY*'

Tried out the path blend and it all seems to be working correctly, just thought I'd bring this to your attention.

SOLVED,

Just had to change the spelling of GREY to GRAY.

Thanks! Darn American spelling! I also spell colour with a "u" which often breaks code on me...

Back to work after a hiatus.

I started renaming things inside the script source for v1.3, v1.4, and v1.4wStatus, w/o making copies ("we don't need no stinkeen safety nets!") and ended up learning more about Scheme than I ever wanted. Hard to concentrate with the little voice sobbing, "What have we done, what have we done?"

But I did get it all put back by theorizing that it might be possible that SOME things in the script DEPEND on some OTHER things in the script. (I had renamed something that I took to be informational only to discover it was that and operational.)

THE REASON FOR THE POST:
I discovered, and turned on (by uncommenting) this debug statement:

Code: Select all

(gimp-display-new img) ;uncomment for debugging...

which I find Very Useful Indeed for tracking progress along the path.

Thanks for having that in there Rob. And thanks again (from 2014) for the paradigm-shifting script.

Cheers!

we've probably talked about this somewhere else, but a search gave me nothing - i've tried and failed to download the path blender to see if it would run on my antiquity of a laptop. where would i download the script from now?

AnMal, Have you tried the link in the RobA first post? When I select the link in Firefox an Open/Save dialog pops-up. If that doesn't work for you try Right click, Save Link As...

odinbc:thank you! i didnt get any result when i just clicked that link, but right clicking and choosing "save as" actually did the trick

My first try with your script. Rob, thank you so much for such a great one and sharing it with us all. :tyspin

jazzon · **Posted:** Tue Aug 25, 2015 2:18 am **(#73)**

Darken the verticles (just a touch), and add a stamen and it would be just looking straight into a flower!

Great job!

Issabella · **Posted:** Tue Aug 25, 2015 2:34 am **(#74)**

Thank you jazzon for your tips. I'll try to do it. :bigthup

Rob, I tried your script on a lemniscata shape. It worked all right but taking a long time to give the result and giving this message at the same time. Perhaps is it because of the shape?

Issabella · **Posted:** Tue Aug 25, 2015 11:56 am **(#76)**

Another one, this without error message.

Issabella - very nice blends and shapes and thank you for leading me to this script, which I downloaded this morning to have a play and test out.

How do I put this politely ... I cannot ... I am absolutely 'gobsmacked' by the very first results; two simple shaped paths two different runs of RobA's script, one using a gradient with alpha content, a bit of background jiggery pokery and 'bingo'...

... and I also get to drink lots of coffee while its processing

This script really rocks, I hope it keeps raining here ... :jumpclap

... thankyou RobA.

issabella & oldmangrumpy: wow, you two were quick! and i agree with you that the results you get with it are amazing and lovely. for more complex shapes it's tricky, though, you have to know what you're doing and i don't always

.

i envy you both your playtime, i don't have much of that since i started working

Issabella: How did you make that wonderful shape in the first place! That's gorgeous!

OMG: That looks (the transparent part anyway) like something succulently dangerous in a sci-fi or fantasy game!

Anmal - work ... yes I vaguely remember that, seems like so many years ago now.

But this script is awesome and surpring with its results; I have no idea what the outcome will be, but I can't stop playing with it ...
