I spent a lot of time in preparing/adjusting this style.
It started from an experiment conducted by Tin (with the help of Ofnuts) one year ago approx, but I don't remember exactly a link to it.
It creates a brush starting from a texture and applies it on the image following (rotation included) the borders of each selected colour area.
Unfortunately, during my tests I discovered that it's not well supported by the current version on Gimp: after some trials (5 to 10 usually), Gimp shuts down suddenly.
I tought it could be my environment, so I sent the experimental filter to my friend Issabella to have a double-check: she confermed the same bevaviour.
Then I tried also to install Partha version (I usually run Samj's version), but in that environment the performances are so bad (for this filter) that I could not procede with the tests.
Bottom line: I open this thread to follow my "special alphabet" philosophy of drawing filters, but it will remain "suspended" until I get a version of Gimp where no sudden shut-down occurs.

Just to see what we are talking about, I post here some outcomes.




Outcomes look different each other because of the source pattern used to create the brush.

Yes, you are right Diego. It's a pity that the new version of Gimp doesn't support the process of this nice drawing effect G.
Anyway, I post a few of my results in G effect.

Thanks a lot, Issabella, for the very nice outcomes.

Slowly, I still worked on the wip "suspended" filter.
A new outcome.

It is a shame that there is an incompatibility. I like the lovely outcomes on most all of the images.

Can you enlighten me on what you think is causing this to happen?

@Mahvin
I guess it's on creating new temporary brushes, use them, then delete them, at each run.
And during tests you have a lot of runs...
I'm still working on that, hope to have a solution.

Only to recall this style.
Worked a lot on the procedure, reduced drastically the gimp "fatal errors" or simply "auto close", but still from time to time it happens.
Added also new strokes (new patterns which are transformed into brush strokes by the filter).

Same image, but stroking with a smaller generated brush.

so not available for 2.10 yet?

I prefer to wait for a release that does not cause Gimp to abort.
It would be a "poisonous" gift to the user.
In any case I will continue testing (and improving) it.
As I made today, I will tell when some significant step forward will be reached.

I like vegan Humans a lot.

What are you talking about?

Who is there?

Remembering...

What do you think, Sir?

Dinasset, I find your outcomes to be very nice.
I have continued my tests with this style.
Some images are more suitable than others, so they admit this style better. IMO
Also, I must say that there are still auto-close events by Gimp, but more rarely.
I post some of my results. Some of them I have applied to the black mask a selection with a gradient and played with layer modes, after that.
