Hello folks !

I'd wanted to share some news with you about the G'MIC project. I've just added a new filter today in the G'MIC plug-in for GIMP, located in Artistic / Brushify, which basically try to repaint an input image, using a user-defined brush.
This filter requires the latest version 1.7.0 to work properly.

Basically, it is how is looks by default:



How it works ? Well, that is quite simple. On the top left of the preview window, you can see the "brush" that will be used for rendering the image.
The filter actually paint over the input image with this brush, and rotate/rescale it locally according to the image geometry : if there are contours,
the brush becomes smaller, and oriented along the image contour. There are a lot of parameters to set the different behaviors of the synthesized painting process.
Now, the interesting thing is that you can choose between pre-defined brushs (rectangles, ellipses, octogons, and so on...), but you can also specify
your own brush, by painting the brush shape on a top or bottom layer.
This, plus the different parameters available make the filter very versatile. Possibilities are almost infinite

I show here a few of the experiments I've made with the same single input image. You can already see the range of different results you can get.



A zoom on the image details :



Isn't that nice ?
If you want to play with it, just press the 'Update' button, as usual, and the filter should appear in the Artistic section.
Beware, it may takes a lot of time to render (particularly if you choose big sizes for the brush).
The filter is parallelized anyway, so having multiple cores helps a lot !

Of course, I'd be interested by what you get ! Please share here

Looks promising David, but slow on my computer (relatively speaking; this one took around 3 minutes (give or take; wasn't timing it; lol).

Original tried this with the picture dimensions 4896x3672 after 25 minutes gave up.
I resized it to 896x672 and it took just a couple.
I have a 8 core FX-8350 oc'd to 4.5 ghz and 16 gigs of memory.
all 8 cores were @ 98-100%
It works great on smaller pictures !

Thank you so much David. I like it a lot as the results are great.

I tried Stars but I didn't post as the Default didn't look like much. Must have to fiddle around to get a good result. Reminds me of Gimpressionist.

I get this result, but with a trick:



using the following values:



After this, I applied the main steps of this PhotoShop tutorial with these Gimp filters:

Clairs & Obscurs by Samj, similar parameters values as PS
Morphology Edges Detection by Leon, power:4 and Invert
Advanced Tone Mapping by tasuki, default values

In the same way of work:

I like your results Jamac, they are good.

Wow! That's kind of a neat effect! I used a photo of some Phlox...

I love it! Though it really needs a lot of power and/or time... Attached picture in size 3068x562 (showing only one half here) took 3 minutes on my Phenom 9550 with 8 GB, I've never seen all 4 cores at 100% before. Double power would be appropriate I guess...

I decided to try this filter out for Memorial Day. All your work is appreciated David!

Playing with Brushify and using my own brushes. Here are some results and I am including my brushes for Brushify.

Here are my brushes because I could only attach 3 at a time.

Heart brush at default, thank you for the filter.
