(it only affects opaque areas, but does not antialias between opaque and transparent parts) - Do you maybe have a newer version around? ciao, --mitch ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

Hi there! Michael Natterer wrote: yesterday, i stumbled across this mail, and it looks as if this plug-in is doing exactly the right thing to lineart images.

It wouldn't be my first choice as I took pains to non-taint it in the first place, but re-licensing to GPL is one of the things implicitly permitted by the existing license so if you must, do so. - Do you have any link to that Scale3X algorithm? I would be nice to include an URL in the help. This was *probably* the page I used as reference: http://scale2x.sourceforge.net/algorithm.html though to be fair that's just a page of pseudocode not especially clearer than the plugin's. :) - Is the behavior on images with alpha intentional? (it only affects opaque areas, but does not antialias between opaque and transparent parts) It refuses to antialias between not-entirely-transparent and entirely-transparent to avoid the possibility of giving some partial opacity to undefined colours. This was intentional but heavyhandedly implemented; there is likely to be a more delicate compromise. - Do you maybe have a newer version around? I'm afraid not; it was a one-day fire-and-forget experiment. Since there's some interest I'll have a quick hack to change the moronic subsambling kernel right now (n.b. that's not related to the alpha thing) and if the results are better I'll submit a patch.
