Anti-alias Plugin

Anti-alias Plugin is an extension developed for Paint.net, which facilitates a simple interface for customizing settings when it comes to the anti-aliasing effect. It can be handled not only by experienced users, but also those new to this well-known graphic editing application.

Easy to set up and access

Unlike regular software products, this tool isn't wrapped in a setup kit. Instead, it's packed in a single DLL file that can be downloaded and copied to the "Effects" directory of Paint.net's installed files.
If the photo processing utility is already launched, it's necessary to restart it to be able to access Anti-alias Plugin. It can be found in the "Effects" menu, which is marked by a small icon that looks like a puzzle piece (applies to all Paint.net third-party plugins).

Set the anti-alias amount, strength and soft outline

The main panel is small and shows all tweaks provided by the tool. It's possible to adjust the anti-aliasing amount, strength and soft outline by moving a slider or by entering the numerical values, in case you have these exact details at hand.
Any of these three settings can be reverted to default with the click of a button. Another aspect worth mentioning is that the modifications made to the photographs can be viewed in real time, which means that there's no need to commit changes, preview effects, and undo your actions if you're not satisfied with the new images.

Evaluation and conclusion

It worked smoothly in our tests, without causing Paint.net to freeze, crash or display error messages. Although the plugin hasn't been updated for a long time, we haven't experienced any compatibility issues with the latest version of Paint.net.
Overall, Anti-alias Plugin offers a solution for Paint.net users looking to easily adjust anti-alias settings for photographs.
