Bonjour,

File > Create > Patterns > Pursuit Curve ...

Each polygon is saved as a path.

The script-fu "Pursuit_Curve.scm" is in the archive "Pursuit_Curve_Version-3.zip".

Edit 20130527 : Version 5 - More options for filling polygons.
Edit 20130527 : Version 4 - New option : Fill polygons gray / Remplir polygones de gris
Edit 20130526 : Version 3 - Ajouts : Types B , C , Inversion A , Inversion C | Tangency / Tangence
Edit 20130525 : Version 2 - Changes on the advice of Saulgoode and add "Variation forme polygone".

That looks really cool samj. Are your scripts only for 2.8 or will they work in 2.6?

If I might offer a couple of suggestions, though nothing of critical importance.

When you are creating a new image, I'd recommend using 'gimp-undo-disable/enable' rather than 'gimp-undo-group-start/end'. There is never any need to undo things with a brand new image; it just takes you back to a completely useless, empty image. The individual steps in an undo group also use up steps/memory allocated to the undo history, potentially causing GIMP to forget undo steps from other images that are open.

Also, 'gimp-context-push' should save all of the settings that you are currently storing in temporary variables (e.g., 'old_context-antialias'). All of the original settings can then be restored with a single call to 'gimp-context-pop'.

Finally, you might consider using 'script-fu-menu-register' instead of specifying the menu path in 'script-fu-register' (a methodology which has been deprecated).

For example, instead of:

Code: Select all

(script-fu-register "Pursuit_Curve_samj"
                    _"<Image>/File/Create/Patterns/Pursuit Curve ..."
                    :
                    :
                    :

use:

Code: Select all

(script-fu-register "Pursuit_Curve_samj"
                    _"Pursuit Curve ..."
                    :
                    :
                    : )
(script-fu-menu-register "Pursuit_Curve_samj"
                    _"<Image>/File/Create/Patterns"

Looks really good samj. Thank you again.

sallyanne · **Posted:** Mon May 27, 2013 6:40 am **(#13)**

Took me awhile to find the location - finally figured out why I couldn't find it. Hadn't restarted my gimp. (oops). Then I had another while to work it out but finally came up with this. Haven't tried adding colours yet.

Last one for the night - to get it in my brain how it works

Thanks again Samj

Hi Sallyanne,
Just a hint, if you copy new '.scm' scripts into your gimp, you only need to 'refresh' the scripts rather than exit and re-start gimp.

Use Filters->Script-Fu->Refresh Scripts

Thanks FB, will have to remember that.

sallyanne: nice job on those! i really like the one where you added the supernova.

sallyanne · **Posted:** Tue May 28, 2013 1:45 am **(#19)**

Two more

After colouring this with two gradients I added a flower to the centre and then a 6 sided polygon to the centre of that.

Coloured the same then added a swirl on top.

Wow, Sallyanne. That top one really has depth.

When I stare at the center, it starts moving and I feel like I've been hip-mo-tized. :shock:
