Flip Selection Effect

Flip Selection Effect is a plugin made for Paint.net users, which offers a simple solution for flipping an entire picture or just a selection. The movement can be done horizontally or vertically.
The tool contains just a couple of intuitive settings that can be figured out even by those who have just started getting to know this advanced graphic editing utility.

How to set up and access

There is no installation kit involved. Unlike regular software products, all you have to do is copy the downloaded DLL file to the installed location of Paint.net, find the "Effects" subfolder, and drop it inside.
In the following step, you can start or restart the tool to commit changes, as well as open the "Effects" menu to view and use Flip Selection Effect. It's marked with a tiny icon that looks like the piece of a puzzle, which can be found near all plugins originating from other sources than Paint.net.

Flip selections horizontally or vertically

The control panel of this add-on is very small. By using the Paint.net built-in drawing tools, you can make a selection in the image and resort to this plugin to flip it horizontally or vertically, by just specifying the preferred action from a drop-down list.
Unlike other Paint.net plugins, this one doesn't have an option implemented for previewing the new flipped image. This means that, if you're not pleased with the outcome, it's necessary to undo the action or remove the newly created layer to make new adjustments. There are no other notable options available here.

Evaluation and conclusion

We haven't experienced any compatibility issues with the newest edition of Paint.net in our tests. Thanks to its straightforward options, Flip Selection Effect can be easily used by anyone.
