ofn-tartan - Ofnuts - 06-07-2021 Somewhat automated a recent tutorial. Starting with this: [attachment=6148]
The script produces this: [attachment=6147]
And optionally this: [attachment=6149]

Would it be easy (or possible) to make the plugin insert pre-informed silhouettes (logos, etc) into the final unhatched areas of the tartan? I wanted to get something like this (obtained after execution of the plug-in - manually). But understandably what I get is something like: Not a real necessity, as manual insertion is possible and not so laborious. RE: ofn-tartan - Ofnuts - 06-08-2021 There are no un-hatched areas. Like on a real tartan, you get a uniform color when warp and weft are the same color, but in 4 consecutive vertical pixels two are from the warp and two from the weft. And the hatching is really the alternance between warp and weft, because tartan is woven like this: [attachment=6154]
RE: ofn-tartan - Ofnuts - 06-09-2021 A couple more fixes (performance improvement and image names). RE: ofn-tartan - Ofnuts - 06-10-2021 One more performance tweak (100x gain ), and a None option for the weaving pattern.

The new 'None, Transparency' option is cool! =============//-//=============
I started with a 100x200 px image, getting a 400x400 px tile to be used as a pattern. But I needed to reduce this pattern by 25% (maybe even more than 25%) to use it in an image. Even if I set it with Scale = 1;Test image (W/H) = 1; I still get a 200x200 px tile, which is still bigger than what I got with the previous 25% reduction. I use another plugin/script to scale the obtained pattern, but not everyone has this plugin or even knows of its existence. If Ofn-tartan.py could offer this option to get a desired % in the final tile, it would avoid the need for another plugin just for that. Thx! RE: ofn-tartan - Ofnuts - 06-10-2021 If your image 100px wide, you should get a 200x200px tile. Why do you need a plugin to scale the result? What does it do that the Scale tool or Layer ➤ Scale layer won't do?

I can get 200x200 px even with the initial image being 100x200 px. Just use: Scale =1; Test image W=1; Test image H=1; But I wanted it even smaller, so I scaled it down by 25%.

I've done it in the same way so many times that I forgot that there are 1001 other ways to do the same thing! My bad. Thx. |
