Image enlargement software

What's currently the best way to enlarge an image with interpolation?

Are there some tools around which are better than others?

I find the most useful is OnOne Software's "Perfect Resize" formerly
"Genuine Fractals".

it depends why you're enlarging it and what you want to do with the
result. if it's to be printed, let the printer do it.

yes.

ImageMagick tools have more options and a better selection of
filters than anything else.

That is the easiest way, but it approaches using Photoshop as the worst
way.

I looked into this at one time for software I was
writing. From what I could gather, bicubic is the
best method for enlarging. I think Adobe claims to
have their own "secret sauce" method that's better.
I don't know whether there's anything to their claim,
but the algorythm is not available, in any case, so
you could only find out if you're using PS/CS.

There was an interesting webpage somewhere that
showed sample images of a lizard that had been treated
with various methods, but I can't seem to find that
page now.

In any case, it will all boil down to adding in extra pixels
to enlarge the image. The only difference I know of is in
how many neighboring pixels are taken into account to
decide the color value of a given added pixel.

nope. the printer designers know far more about what is best than you
do and photoshop is quite good at scaling.

your repeated jabs at photoshop not only show how ignorant you are
about photoshop and what it can do, but just how jealous you are of
quality software you can't use.

more importantly, it's not possible to tell the difference without
pixel peeping and even then, probably not. nobody is going to look at a
print and say "you used the printer to scale it."

But (probably) some softwares are better at preserving edge sharpness,
from what I remember. Some special algorithms to recognise edges and
reconstruct/resharpen them when resizing. I believe I read this
somewhere, but I can't remember where.

First, this is highly printer dependent.

Second, Photoshop gives you plenty of options when it comes to image resizing.
