I have a digital camera which has developed a few stuck pixels and I'd like to automate the process of fixing them.

I figure I can create either a bitmap with said pixels set or a text list of pixel coordinates, but how can I get Gimp to do an interpolation of the surrounding pixels at each of those points?

Thanks!

If you have your bitmap with the dead pixels ready: - add it as a layer to your photo.
- select by color, pick the color of the good pixels - invert selection
- move to photo layer
- expand selection by 1 pisel (selection->expand) - Gassusian blur (filter->bluer->gaussian blur)

The blur, however, will still take in to account the value of the bad pixel, right? Is there any way to avoid that?

And..on gimp-devel, people are talking of a soon-to-be-reality macro recorder that will let you automate this without typing a single line of code.

I was thinking of writing a plug-in and making use of some of the advanced interpolation algorithms present in the "panorama tools" suite, but that's a fair amount of work and a bit more than I'd like to bite of as a first attempt at such things.

let me suggest thinline.c available at the registry.

Okay. I found it, but I the English documentation page seems to be gone. What does it do and how do I use it?

I was thinking some more and figure I might be able to do it as script-fu (I've always wanted to learn scheme). It wouldn't be fast, but there are only a few pixels to do.
