Looks like binary code to me. It sure isn't human readable :)

So you'd have no trouble reading it then? ;)

Or don't you have the appropriate parser installed on your AI yet?

Bye for now,
     Jamie.

It does not compute!

	I get nice results when I render with 1/3 the number of pixels compared
to the dots on the printer. Usually an image that looks good at 100
pixels per inch on the screen will be nice at 300 dpi on the printer and
about the same size. But of course you may like it better at 600 or even
1200 dpi : then it will be respectively twice and four times smaller. So
you'll need two or four times as many pixels to get the same size as it
was at 300 dpi.

	I use The Gimp to post-process my images : that's a lot to learn but it
beats the crap of anything else on Linux. Among other things you'll find
out how many pixels an inch you have right now, accounting for you
resolution and monitor size.

	Have fun.

	Jean M.

	DON'T USE XV to print since it produces crapped ps files
when the image is big (from my experience, don't know why).
	Use The Gimp or other image manipulation system.

My interpretation of the behaviour of xv is that it resizes the image in
such a way that it fits on the screen. This limits the resolution (in terms
of pixels) to the resolution of the screen.

I second this.

	You should compile his nice C source code and see the
result, which is expected from a signature code... I still have
trouble (after more than one year I first time saw Warp's msgs)
to understand how it works. Warp, did you participate to this kind
of "most infamous C code" contest or something like that ?

  Well, this is actually true. The string in the code is binary data
(basically a bitmap) with an offset so that the values are shifted to
printable characters (kind of same type of thing as uuencode or mimencode do,
but more simple).

: Warp, did you participate to this kind

  I have participated in the IOCCC but have no big expectations (the results
are very late this year). The quality of the competition is too high for
me (much like in the IRTC).
