Yes, I agree that the whole filters editor probably needs to be recreated from scratch.

The licensing of a mockup is entirely irrelevant (imo).  The mockup is just an example, not the real thing.  Plus, as Moini mentioned, the website gallery is designed to host mockups.  You could host it in both places, and it could have 2 licenses.  But again, for a mockup, the license isn't very important.  (well, maybe for a proprietary software, but not for open source)

Anyway, it's just that you have so much talent and experience with Inkscape by now, and especially with filters, but with lots of other areas as well.  And your understanding and knowledge could benefit the project on the development side, in addition to helping users.  I was just trying to nudge you towards becoming more involved, in case you wanted to, but maybe just need an invitation, or a little push.


Thank's for the kind words. Surely I'll try getting into it in a way. Some plans for the future.



Also, season greetings to anyone!

New pack, for drawing contour lines around different tone levels of the source object.
Intended use with creating gradient meshes, to help the placement of the mesh nodes.

Interesting!  So you would place the mesh nodes along these lines?  I've been working with just the opposite approach, and I would try to center the nodes between the lines.  I'll test this for you, but I'm just about to log off for the night.  Maybe tomorrow  :)

I see your point. If you increase the number of tone contours drawn then they would fall in somewhere there. Haven't tested myself either, and not so familiar where to place mesh nodes effectively considering the mesh topology.

I was just thinking that the contour lines must fall at the point where the color change is at the maximum.  But the nodes of the mesh is where the color change is zero.

I'm going to try and download the apple image.  Or maybe find some other simple image and test it.

I'm almost finished with my first test of the mesh.  Of course, you know me, I'm aiming for realism!  So I need to find the right kind of filter to make the right kind of texture.  Or I might try an make the texture myself.  We'll see.  You could probably whip out a perfect filter for it.  But I'll see what I can do.  Oh, maybe I'll post it....didn't I make a topic for gradient mesh tests?  I meant to, but I might have forgotten.

Can change the contour lines to have two different colours following eachoder, and then one could say add nodes to the white lines, and the black should be at the middle at the transition.

And posted a filter with that leaf in the mentioned topic.

One could say add nodes to the white line.  But then, why make the black lines?

I finished my leaf, but need to take a break before I tackle another mesh!  They take a lot more time than I ever expected!  But soon I'll test it, I promise.

Made a colour reduction pack, just as V1nce did a few years ago.



Unfortunately there are a couple issues with it.
0.91 renders it off as on the openclipart thumbnail, zooming in more than 5000% blacks out the rendering and somehow the bounding box is off on the clones.

Now another colour reduction filter pack.




Contrary the previous filter pack, which was made by one component transfer filter primitive this one is rather complex.
The last filter in the bottom right is built up from 113 filter primitives, of which there are 18 blurring.


Also, with this one there are other "issues" at openclipart.
They use 0.91 to generate thumbnails and it turns out that 0.91 had a transparent black alpha.
In the filter a component transfer is used to bring up the alpha values of the blurred appearance, and it results in a fading to black in ocal's thumbnail/opened with 0.91.

A variant of the concept, with a blurring added into the chain.



-rendering is off in 0.91-

This can be used better with photographs than the previous one, and 5 tones are enough to create a proper shading in a drawing.
There is a component transfer added in the link which can be used adjusting the filter to the original image's tones.
Will see how this pack can help creating gradient meshes.

Could make some cool abstract art with some of those!  Especially the top-right.

Made a megapack out of that weathered wood grain pack:





And some new variants on the previous triangle tiling:

Some glitch-art wallpapers with filtering:

































Use latest prerelease with this because 0.91 renders them badly due to an issue with the alpha compositing -"transparent black".

"glitch art" - reminds me, I should finish something I've done with the spiro spline scribbling.  I just didn't know there was a word for it!

From that other post, here is the result
-kaleidoscope background reworked from scratch.



This time, no cloning is used for repeating tiles to minimize the number of unnecessary transformations, however preserving the filter transformations is painful.
As there are issues with it.

Same as with the intarsia design, it would be so much easier if there were handles to adjust the filters just like the pattern fills.

Colormap filter extension testing.



Yes, that's right: inkscape will be getting this feature to generate colormap filters into extensions/modify color/adjust/colormap.
At least that's where it is located now -extension made by su_v, available at gitlab:

Those look very realistic!
The majority seems to be different sandstones and shale. Could also be suitable for moon and mars surface :)

And here it is:



Pack of 1024 filters. Not so satisfied with all of them, but in every colour scheme there are filters that look decent.

Those don't look the same as the first pack.  I wonder why?

Edit
Yeah, I learned my lesson about installing whole packs.  There's just not enough room.  I've decided to just install specific ones, when I need them, rather than have so many hundreds not being used.

Although that first stone pack really might be worth it!
