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. I "ported" it to 2.4 API and codingstylized it a bit: http://mitch.gimp.org/auntiealias.c Since we consider including it, I have some questions: - The licensing would be changed to GPL, would that be ok?
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.
