Fill tool at 0% tolerance + Alpha Blend illogical behavior

[avidichard]

It's hard to define exactly so here is a gif of what I mean:

As you can see, the last layer of dots at the bottom before the completely white area is alpha blended when my tolerance is at 0%. I expect NO alpha blend when there is no tolerance at all. If I add tolerance, THEN, I expect it to slightly cover up some extra space blending in but not at 0%. I put 0% tollerance because I did not want the fill tool to tolerate any color differences and since that layer has a completely white area and a completely transparent area, I expect, at 0% tolerance, to ONLY fill the transparent area, nothing more.

As your .gif shows, this occurs with Antialiasing Enabled.

 

With Antialiasing Disabled it doesn't happen.

 

I think it is meant to be that way.

I understand that Antialiasing is supposed to work as it does but not when the tolerance is at 0. A tolerance of 0% means no place for tolerance even for antialiasing. If the antialiasing would happen INBOUND, I would have understood and accepted it, but now, the antialiasing is happening OUTBOUND which means that there is a slight tolerance.

 

The reason I am pointing that out is that I spent time trying to figure out why my dots were grey at the bottom. THEN, I realised that it went over my tolerated color and spilled outside the region I was prepared to fill. In short, the region that should be touched is the same region that the magic wand tool would select and nothing outside.

 

I would have ALSO accepted this outbound antialiasing if I would have tolerated 1%. But at 0%, I think it should stay within the range of the accepted color region from the tolerance slider.

In Settings at the bottom of the Tools section there is an option

to make Antialiasing Disabled your default choice.

That's not the point. I know all this. All I am saying is that a 0% tolerance should not wash over the tolerated area. There should be no outbound antialiasing.

 

Anyways. I am just pointing this out as a possible confusion. It's the author's discretion to decide to work on this or not. I'm not expecting to much because because Paint.Net is already my top editing app I use. Photo editing, sprite creation, wallpaper creation, name it. I just think that at 0% my antialiasing should be inbound if any, not out. It would have helped me search a lot less longer about why I had grey dot issues.
