Have a look here. I made a video showing how I made my snowflakes.

Wallace, I knew you never sleep - thanks for the video reference, its a case of "A GIMP neophyte can learn more from a Wallace video than a fool can learn from a wise answer".

best thing is learning from you guys is fun, in my working days learning was a chore!

You're welcome and enjoy.

2.8.10 32 bit Windows and I am selecting it there as well as making it the 'current selected brush'. Is there somewhere in that dialogue to change the size?

Are you looking to change the brush size?

I know it can be changed in the brush tool options but can it be changed in the window that pops up when doing the Script? I haven't seen any settings there for the brush except to change the type and spacing.

No you can't change the size of the brush within the Extrude from Path script. Also unfortunately, there is a bug that will not allow the brush size to be changed while using Gimp 2.8.10. for this and many other scripts.
The brush size will remain at it's default size. So I would suggest using a brush with a default size that is close to what you're looking to create.
I don't think I'm wrong about this.

@Wallace ... all the gimp neophyte needs is a brush bug!

@Graechan ... thanks for the brushes download; just tested one out and am 'gobsmacked' at the result. Looks like my garden is going to suffer this summer!

oldmangrumpy, spacing means the following. When you run the "stroke path" the spacing will define the distance between a stroke and the following, measured in pixel. In other words, if you choose a small spacing the rope will appear right next to each other, sometimes overlaping. If the spacing is enormous the rope will appear well spaced, with gaps between them. For better understanding, make a simple path and ask to stroke. Change the spacing gradually to observe what happens. Also change the brush to better understand. If I want the stroke to appear alongside each other, but not overlapping, I have to set the spacing depending on the size of the brush. Therefore, the ideal spacing depends on the brush and the expected goal. If I have a 1 pixel brush and I want to fill a line completely, I have to choose a spacing of 1. If the brush is a large butterfly and I want the butterfly to appear sparsely, I have to greatly increase the spacing.

Finally got some free time to play and wanted to test this script.Here is my result using text.



Thanks, Graechan!

That is very cool Tux, it looks like the texture of a balloon where you can squeeze it and it will make a dent... very nice.

Thanks a lot for that info Carlos Diniz it helps a lot; I realise that most such info is available somewhere and that practice makes perfect (well sometimes!) but I am going at such a fast learning pace right now I am probably trying to do different things with insufficient knowledge/preparation - but I love this GIMP so much!!

So onwards and upwards!!

Graechan, I didn't understand. A % of what?

Graechen
Even at 1% some brushes are still too big to create an effect
