Dear me, I thought your lazy mind had decided to duck out of this
thread, but here you quack on again.

Why should I dither when I have the ability to attempt a true
representation of 16-bit? Again, read the fucking thread properly.

Software vendors decide? Dear me! I think it should be the fucking
customer that decides. Bloody hell, are you lot so bloody meek as to
let people like Microsoft dictate to you what you can and cannot do.

As for convenience as an excuse - I call that laziness.

No. He said that JPEG2000 is inappropriate for this venue. He didn't
mention anything about discussing it. Not that there's been much
discussion. Just a load of ducks quacking about not being able to see
the image. Hardly anyone here is willing to discuss the pros and cons
of JPEG2000.

>way to do it...

The time for politeness is way gone. After having one of my posts
mangled by some careless person, you people deserve a piece of my
mind.

Why should I when I have the chance to deliver a true 16-bit image?
Yes, the chances are that it will not be perfectly displayed at the
end machine, but at least the 16-bit intent will be maintained.

This is not the newsgroup for scene files. Bloody hell, get your

Typical. Another lazy person who can't be bothered to think about it.

READ THE REST OF THIS FUCKING THREAD. GET ALL OF THE FACTS BEFORE YOU
QUACK ON LIKE THAT.

What did I say elsewhere? I'LL TELL YOU WHAT: YES, I SHALL BE POSTING
IN JPEG FORMAT FROM NOW ON AT THE REQUEST OF ONE OF THE POV-EAY TEAM
MEMBERS.

I totally disagree with the point of limiting ones options due to
laziness, but those are the so-called rules.

Ok, whatever, pal. You really shouldn't take things that seriously...

Don't be a smart-arse. You know full well the purpose of caps in this
case. Get the message. If this is best you can do in response, get

    Hey, hang on there for a moment and calm down. I don't believe for
one minute that any of the guys and girls here *wouldn't want* a
better file format to show others their images. I for one, certainly
would, and agree with your efforts to show/prove this with JPEG2000.
BUT, sweeping statements like yours above though, Imjer, offend even
me, but then again, who am I? I've been using PoV for only four years,
and I still consider myself as a novice. I'm not a professional pover,
and I know I *never* will be, but I love these groups and the images
posted, and the people here, and the advice and ideas given. To me,
jpg's fine. Hey, most of the time, I don't even see an artifact, so
PNG or JPEG2000 is useless to me!

    The whole crux of this is that you should have presented your
argument in a much better way, present your argument and ask something
like, "I'm trying this JPEG2000 format, I think it's better and we
should at least have a look at it - what do you guys think? Can anyone
download it?"

    You would have then had the honest answers that you required and
could have moved on further to perhaps complete that goal somehow,
perhaps with support from someone in these groups.

   Personally, I think your work is fantastic and wish that you would
post more often, it's not *my* poving style, but nevertheless, I
always wonder how you do such images - you have a great talent there.

   KIS. Keep It Simple. I think we're all FOR moving forwards, but
let's take it one step at a time eh...?

Judging by the lazy attitudes I'm getting I beg to differ.

You must look closer, they are there I promise you.

I posted an image and mainly all I got was grief and some cheeky
person mangling it. I wasn't even posting it to advocate JPEG2000 -
but that's how it ended. I was merely doing it to preserve the 16-bit
output of the POV scene (though that may now be pointless after at
least some sensible discussion om the subject), but also to minimise
the artifacts.

No, my posting just revealed a lot of lazy people with fixed views.

Cheers. Considering that don't use POV much that's a kind comment.

Believe you me, I would have thought that was just a single step.

Anyway, this is all moot. It seems that it actually acceptable to post
such images. So where I feel it is required, I will.

No. I would but I have other commitments. Sheesh. You are too lazy to

I do not know to whom you refer. Normally, I would not swear, but
experiencing the wave of apathy and lame excuses here makes me eff.

It is not lazy, it is merely a part of the language. People with
notions that swearing is somehow wrong are generally wrong in many
other matters too.
