White line around textures with alpha channel
This uses to happen me for a long time but I used to know a trick on Paint.NET to fix it, but seems it doesn't work now. Basically, on textures with alpha channel and transparency, there's a white line arround the opaque part of it. It's very odd and look bad in game, and seems there's no way to fix it. The line is not on the texture. Does anybody knows how to fix this?

I suggest to use GIMP or another similar free program to get a better managing of the color and alpha channels. I don't see Paint.Net good to work with games textures and the TGA format.

"with games and the TGA format"
Paint.NET writes proper TGA files that match perfectly to the TGA specification.

I didn't meant that Paint.Net is bad in saving in TGA format. From my little experience with that program, I suddenly noticed that isn't possible to view and edit the color and alpha channels separately, this last very important for games textures making. That's what I meant.

Thanks for the answers. I downloaded and tryed GIMP (which I tryed before, back to my first days here when I began learning about image editing). The editable alpha channel is surely an advantage there, however even on that software I couldn't fix the issue because technically the alpha channel is working properly.
After some search on the Web I found that in some games, when textures using transparency are stretched on the objects, the alpha channel may not be presented properly and it's visible part of the pixels alpha channel was covering (white) and the way to "fix" this would be changing the color of the pixels covered by the alpha channel to the same of the rest of the texture, so the white lime I'm game would be unnoticeable. But, maybe because of my lack of knowledge about GIMP, I couldn't do so.
Anyways, I found a plugin for Paint.NET that could cover up most of it, AA's Assistant.
