Once you create paths, you then stroke with a 1px dot with 800px spacing, Diego. You then save the result as a PBM file and reopen it (converting to 2-bit doesn't cut it and I've not tried to find an alternative method). Once you get your dots, you run G'MIC>Contours>Skeleton (quick method) which converts those dots to blocks. You then invert for the mask. I add an outline (isophots) to give you a more accurate mask. Use the mask under Testing>Lylejk>Blend (shape average) to colorize the blocks.

OK Diego; quick and dirty tut.: viewtopic.php?f=10&t=13703

No reason to start yet another thread. I used di Blasi's mosaic creator just to create the outlines (see attached) and then did some advanced texturing to make the cobbles look real.

These are exceptional, Lyle. Now wouldn't it be great if a filter could be created to do this for us technically disabled!

I'm hoping Diego is working on this 2-ton.

Nice one lylejk.

Thanks Odin; cheated a bit with this one (used Amphisoft's Metalwork2 as part of the texturing.).

Yes Lyle, I'm working...
I need a lot of tests.
When ready I will post my "variation on the theme" following your tut and hints.
The filter will be called "DIEGO_Mosaic_Lyle_Style"....

Looking forward to trying it, Diego.
