Point Warp

Point Warp is a small-sized plugin designed for Paint.net users, giving them the possibility to apply a point warp effect to any selected spot in their images, which is basically a bulge effect.
It comes packed with several customization options that can be easily tackled, even by those with little experience in this advanced photo editor.

Simple integration with Paint.net

There is no actual setup kit involved. Instead, you can download and copy the DLL file to the "Effects" folder of Paint.net, whether you have an installed or portable edition available.
If the application was already launched prior to this step, it's necessary to restart it to finalize setup and gain access to the new extension. It can be found in the "Effects" menu, which can be quickly spotted by the small icon that looks like a puzzle piece.

Apply warp effect and customize settings

After loading an image and making a selection using the built-in Paint.net drawing tools, you can bring up the configuration panel of Point Warp to apply the bulge effect and configure settings related to the point width, distance, center, direction and radial influence.
This can be done by moving sliders, entering numerical values, or clicking on arrow buttons to increase or decrease these values. Any setting can be reverted to default with one click.
Worth noting is that modifications can be previewed in real time, so there's no need to commit changes just to be able to view results and undo the action or remove the newly created layer if you're not pleased with the outcome.

Compatibility issues with the latest Paint.net

The add-on hasn't been updated for a pretty long time and this is probably why we've experienced compatibility issues with the newest version of Paint.net in our tests. However, Point Warp still works smoothly with older editions, enabling you to apply a bulge effect to photographs and tinker with filter properties with ease.
