but shouldn't those transparent pixels be 255*3 ? I do want a WHITE line. this is okay, I can just use brightness or up the tolerance a little.
this happens even with anti-aliasing off, I'm not talking about those edge pixels, it's the main part.
and I just tried this
open paint.net--add a new layer
1. if I fill it with 255*3 trans-alpha from 1-48, then use color picker to check, it is exactly the color I use
2. if I fill it with 255*3 trans-alpha from 49-254, then use color picker to check, it is 254*3 trans-alpha the same
(overwrite, not normal blending)
(ok, I just did again with 128*3, even weirder, 128*3 trans-alpha 5 turns into 153*3 trans-alpha 5)
and can someone tell me the right way to say a color with transperancy, please? :oops:
