Question

I’d like to be able to programmatically distort an image in C#. Specifically, I’d like to re-weight an image spatially, such that the central pixels are expanded and peripheral pixels occupy proportionately less space. Think fish-eye lens. Kinda.

Are there any .NET tools that can do this? I don’t mind whether they’re built into the .NET core, or an addon.

Our free imaging SDK DotImage Photo Free, can do this:

Look at Atalasoft.Imaging.ImageProcessing.Transforms.LensTransform. You would do something like

AtalaImage img = new AtalaImage("file.jpg");
LensTransform cmd = new LensTransform();
cmd.Radius = 100;
cmd.Offset = new Point(100, 100); // set the center
AtalaImage img2 = cmd.Apply(img).Image;
