Can I scale a selection region from the center?

[atkulp]

When I select an image against a solid background to convert it to a transparent background, there are often extra half-background pixels due to the anti-aliasing. Is there a way to either a) scale the selection toward the center instead of from a corner, or use a smarter selection tool to outline an object and convert anti-aliased pixels to their semi-transparent equivalents?

Sorry if this is a common question or there is a common plugin for it. I'm a long-time Paint.NET user but first-time poster. I searched the forums and tried some plugins first!

that blasted outline is a scourge to all, and i know of no selection tool that can handle the job. however, hope is not lost! the feather effect is here to save you. cunning use of this miracle of PDN will fade those edges perfectly. and dont forget feathers best friend- AAs assistant. when these two team up the results are astounding.
