G'MIC

Thanks Nicholas!

For instance, src/gmic_stdlib.h and src/gmic_stdlib_community.h, and also all the gmic-qt folder that is present in our .tar.gz archive (will the translation files auto-generated).

OK, I will do that from now. The issue with github "releases" is that it requires a tag, and for G'MIC, the code in the github repository is not exactly the same as the .tar.gz file we provide on the website (in it, we add additional generated files that are actually required to compile G'MIC properly).

Hello Nicholas, Is there something I can do to help passing the info more easily?

That's because there were already a filter named "Twisted Rays" by someone else, which has been renamed to "Twisted Rays [Samj]". Press the "Filter Update" button to get my newest version.

Here it is, I've added a new filter in the G'MIC-Qt plug-in, named Rendering / Twisted Rays. It should cover most of the case @frio described in his post. And with a bit of scripting, you can render nice animations too 😁 I hope this will be useful for someone!

Super cool @frio, well done. I think the whole process would make a cool new filter in the G'MIC-Qt plug-in !

Hello. FYI, the G'MIC project celebrates 15 years of development. For this occasion, I wrote a progress report of the development done this last 1½ year : https://gmic.eu/gmic325/ If you are interested by the project news, then this (long) one is for you 😉 Thanks to @null54 for making our G'MIC-Qt plug-in available for Paint.NET. Cheers, David.

Really I don't know. I'm not the author of this particular filter ("Dream Smoothing" has been done by Arto Huotari), so I cannot say why it behaves like that. There might be some hidden parameters automatically set according to the specified number of iterations, in the filter implementation. Arto could tell us, but I'm afraid he is not around (nor on the G'MIC forums). His filter got its latest update almost 10 years ago... EDIT: I've checked and the code of the dream smoothing filter definitely computes some smoothing parameters according to the number of iterations (see https://github.com/GreycLab/gmic-community/blob/master/include/arto_huotari.gmic#L71). So that explains the difference.

Suggestion : Select the filter you want to apply multiple times, then click on the "Copy the G'MIC command button", located on the top-right of the filter parameter (just beside the "reset parameters" button). It will copy the G'MIC command in the clipboard. Then, select filter "Various / Custom Code [Local]", copy-paste the content of your clipboard in the "Code" section (replace everything that would be already set there). And now, embed it with a "repeat { ... }" syntax, as shown in the image below. Click "OK", and you're done.

I've written a report about our two last years of developement on the G'MIC plug-in. You may be interested : https://gmic.eu/gmic300/

My fault, sorry. Everything should have returned to a correct state now. Users of G'MIC 2.9.7 will get your filters working as expected.

Interesting to know, thanks @null54!

Why isn't it possible to do like in GIMP and Krita, and be able to pass multiple layers to the G'MIC plug-in ? Are there any technical limitations ?

@ScrapbookWithPDN, many thanks for the kind words. We have good news to share, as we have been able to fix the various performance issues we got for years on Windows. I'll release a new stable version 2.4.4 of G'MIC tomorrow. Hope you'll notice the improvements with the "Stylize filter" !
