I took the binary of the mosaic from Gimp 2.4 and put in in Gimp 2.10's plugins and now I have the legacy mosaic filter.



I recommend others follow as the current mosaic filter is WAY TO SLOW!

Can you share it please, I'm very interested in it (I'm on Linux)

By the GPL's regulations I have to link the source code which is in here somewhere when you search for mosaic.
https://download.gimp.org/pub/gimp/v2.4/

UPDATE-Source Code for 2.4's Mosaic is here.

Now here is the binary that only works on Linux. It goes in the normal plugins folder.

Why did you take the 2.4 one? The 2.8 one should also work and its history says:

2013-09-22 Bug 677275 - Mosaic Filter produces ugly artifacts

This 2013 date is contemporaneous with the 2.8 versions (2012-2015).

Edit: Some Git magic shows that the latest fix is in 2.8.8.

The source of the latest 2.8 is here. On Linux you can likely download it and compile/install it with the gimptool utility.

I have a chroot of Gimp 2.4 on my Linux machine that I made using a tool called CDE (Code Data Environment) back in 2019. I tried porting Gimp 2.8 using CDE and it failed. Only 2.4 worked.


CDE is like an ancient mid 2000s precursor to flatpak and appimage

Thanks for the binary, it's working fine
Although it's way faster it has the exact same behavior -> the shadows hard to remove,
more to study for me => on everything opaque single color it draws the grid by making transparency (kind of color erase mode)... but if I check then uncheck it does it black even if my FG/BG are all white .


Thanks, that nice, but how do you do that (compile)?

AFAIK gimptool handles the compilation, it identifies the particulars of the local gimp installation and calls GCC with the adequate options...

And in English, like normal English, not programmer English, what do I need to do?

A Gimp 2.8 version ? I have one of those tucked away. From Gimp 2.8.22 Unzip, pop it into your user profile plugins folder. Find it bottom of Filters -> Distorts along with the other non-GEGL filters

Thanks a lot rich2005

I did many tries and comparison, with the 2.4, the 2.8 and the GEGL...
The 2.8 is capable of drawing (while triangle is selected) and horizontal transparent line with the other black or white...

2.4 and 2.8 are faster than GEGL, but can have some unexpected behavior depending on what color it is drawing, and may have some bug (like need to deactivate then activate again the FG/BG to get the right color) where GEGL is consistent and feel bug-less .
The drawing itself is the same as GEGL (that tiny shadow for example) but with GEGL you have more options which can "trick" that shadow to not appear.

In the end I did remove 2.4/2.8 as GEGL might be a little bit slower, but IMO it's a big improvement compared to 2.4, and 2.8... like night and day
In all case thanks a lot @contrast_ and @rich2005 for providing these version, it was very useful to me for these tests

I still use the large preview Filters>Distorts>Mosaic filter and it works fine in Gimp-2.10.32



If anyone is interested i will upload the zip here.
