Hi Greg.
I like your new Avitar.

What do you mean by "defished".

Thanks. Defished means that an image is flattened using a particular software, removing the distorted horizon and corners caused by the fisheye. Thus the term, defished. Or perhaps, fish-no-mo, or possibly nonfishiness, or bychance unfishified.

And if you want to un-unfishify it - is that what the "Scale Image" tool is for?

http://www.epaperpress.com/ptlens/index.html is what I use.

fish...scales....ok, it was pretty weak

I totally missed the pun.

Thanks for the explanation.

Yes, well, I'm pretty embarrassed by how weak it was. About 20 years ago, they'd cleaned up the River Thames in London enough that fish reappeared. I tried to make a joke that next they'd clean up the glaciers and the price of frozen fish would come down. I still think that's funny but nobody else seems to...
