Francis:
I've only heard of Livepix as well, and heard of others seeing demos.
It is one incredible revolution in pixel pushing. The best analogy to
describe Live Pix is that it will do to pixels what Postscript did for
typefaces...namely get rid of the jaggies!
They call it resolution independent...but the size of your original
scan will still limit what you can do. The FITS (functional
interpolative transformation system...I think that's what the acronym
means) system is really a brilliant idea. So much so that Kodak has
bought into FITS imaging (the muscle behind Live Picture) and will
incorporate the technology into the new interation of Photo-CD.
The biggest feature is that it allows you to work on an image in real
time, and then "render" the image to the file size you need
afterwards. Then you can do a quick render and get a laser copy, or
fax off to the client...and then if they want it billboard size, you
go back and just re-render...no hours at the monitor!
Part of this is available in Micrografx Picture Publisher 5.0. They
have a "virtual imaging" system that allows you to take a low res
proxy of the file. You do whatever manipulations you want on the
image, and then save the set of operations as a command list or MACRO,
close WITHOUT saving. Reopen the full res file and apply the macro.
I'm been able to successfully render a 14.2 MB file from a Photo-CD on
a 90MgHz Pentium with 16 MB of RAM. It's really sweet.
JPEG can definately get "funky" looking if you go too far. Again, best
to do some fine tuning by running the system all the way through. You
may find that you get OK results using a file twice as large, and then
compressed 4:1 JPEG. Another option might be LZW or some other form of
lossless compression.
Nice talking with you.
