Nice, you did all the work of adapting the algorithm for my needs. :D

 

A fast algorithm indeed.

Edge Expander can be used to remove thin scratches from photos:

 

1. Erase the scratches with the Eraser Tool.

2. Duplicate the layer.

3. Use the Edge Expander on the lower layer.

Guess : What is hidden in this image? Use Edge Expander if you can not see it. :)

Very interesting, Eli!

 

In my initial comment I said:

Though the plugin was mostly written as an experiment, I can think of a few possible uses for it, including softening edges for antialiasing and as a sort of more flexible Crystallize effect, which I'll explain in a follow-up comment.

 

I never did post a follow-up comment, but that's the type of thing I had in mind. The effect is much like Crystallize, except the distribution of the centers (and therefore the distribution and size of the cells) can be modified.

IS it possible to use this feature to match the "expand image" feature in Micrographix's Picture Publisher 10 where you can "add" some additional blank cells to an image

I want to add / paste an image alongside an existing image so the final result is as if the two were stuck with selotape

To answer the question, I'd need to see examples of what you're talking about.

It's OK, I worked out that the Expand Canvas "sort of" does what I want, the nice thing about the Micrographix solution was that you could expand all 4 edges by differing amounts, whereas the Paint.Net solution old extends the Right & bottom edge

Not so. Anchor the existing image to the center and the canvas will be enlarged around all four sides.
