We aren't talking about printer software, we're talking about what the ppi tag embedded in a digital image does. We haven't even sent it to a printer yet.




If x=y, then x*z=y*z. That's called proof.

But what you're doing is not a proof.
What you've been doing is a demonstration; you're using particular numbers - results may be different if you used different numbers, and you don't know in advance which numbers might be important. That is where the software comes into play - that is where you find the x, y, and z.

Example: A prime number is a number divisible only by 1 and itself.

Dman's Theorem: "All odd numbers are prime"

"Proof"......
1 is divisible only by 1 and 1 so 1 is prime.
3 is divisible only by 1 and 3 so 3 is prime
5 is divisible only by 1 and 5 so 5 is prime
7 is divisible only by 1 and 7 so 7 is prime
that should be enough to show the theorem is right.

The problem is that 9 is divisible by 1, 3, and 9.
In fact, we could find an infinite number of odd numbers that don't work.
For a proof, you have to go beyond just numbers, and you haven't done that.

I don't know what the printers are dealing with. We would have to look at every printer driver in use to be absolutely certain of your words. I think it is likely that modern software doesn't look at that parameter, but we don't actually know that.


added: "m is divisible by n" means m/n is a whole number

Sigh. The x is the ppi and the Y is a pixel dimension. They're not buried somewhere in the software, they're right there for you to see. Here's a screenshot showing you the x and y. Try multiplying one by two and see if the other is also multiplied by two. If you want to know if this is true in all cases, I simply refer you to the Multiplication Property of Equality.

Again, we aren't dealing with printer drivers. Photoshop is not a printer driver. The ppi meta tag is embedded in every image on the web. Printer drivers don't affect those images. We're simply asking what effect that ppi tag does and does not have on a digital image.

You have got to be kidding. Neither the way you asked the question, nor the way you answered it was very well done, in my opinion. But the important point is that you were not sincerely asking a question, as you already knew the answer. Instead, you were trying to disrupt the new section and you then dragged us all through this ridiculous charade.

The rules for participating in the section read, in part, as follows:



You were not having an issue with "resolution," you were not seeking help, you were not being clear about your intent. You wanted to "settle the age old questions" and to get "each of you" to respond, and to "get a consensus." Granted, you have been very clever in all of this, as you slyly tried to exploit any weakness in the new section and in the comments by the members here, members you have insulted and played games with here, but that only makes the offense worse.

I fully support the moderator locking that thread, and furthermore I would support you being banned from the site for what you did here on this thread. You have been lying throughout this entire fiasco.

You keep on saying stuff like that and not backing it up with details. Please, tell us what parts you didn't think were well done, and why. I suspect I'll hear what parts weren't clear right after you tell me how I was misleading people about Adobe.




For a guy that's complaining that I wasn't clear about my intent, you sure seem to know what my intent was.




Asking it questions? Are answering questions its weakness?

I support you being banned from the site for constantly accusing me of things and not being able to back any of it up. I back up what I say. You don't.

rehess Loc: South Bend, Indiana, USA

I was with you until you started appealing to the Queen of the Sciences. Mathematics is not a genie that you pull out of a bottle when you need something to support you. And, images do not exist in a vacuum; the ultimate meaning of these parameters is what the software makes of them - until you actually see that, you have an incomplete understanding. Thus, I'm not willing to sweep away what the printers say without seeing an actual print from their systems; they may be experts also.

Meanwhile, I have things to do today. I'll stop by later with my popcorn and see if you've made any progress.

TheDman Loc: USA

Heh, wow. Because who would use math to examine relationships between numbers, right? Actually it IS what you "pull out of a bottle" when you're examining numbers. Without math, you wouldn't be typing on the internet or have a digital camera. I've never seen anyone argue against using math before. I don't believe there can be any clearer way of showing you're on the wrong side of an argument. You're in new territory here.



They exist on the internet, which may as well be a vacuum as far as printers are concerned. There are billions of images on the internet, 99.99% of which will never be printed. So please, tell us what effect a printer driver has on them all.

TheDman, You were trolling, I was trawling.

Full disclosure:
_____________________________________
When you created your thread you intent was blatant.
I was in a no win situation.
If I locked the thread you would have had cause to scream bloody murder. A loss.
If I unlocked, I exposed the mentors to potential grief. Also a loss.
I unlocked and in PM sent a warning MSG to ALL the mentors.
Some did not read it (even as now) other did not care and a couple who felt the same way I did asked me to kill the thread.
Since I knew killing the thread was a bad idea, I did not. I let it go but watched for your answers, if any.
Your first answer was not unexpected but not sufficient.
You second answer was the hook I needed.
I blocked the thread, for cause. A win.
_____________________________________
Contrarily to your premise that I was posting as a mentor I posted as a moderator.
I subsequently created a public thread in the main photo area to report the moderation action and create a discussion on what happened. The admin nixed that. I did not anticipate his reaction.
_____________________________________
In the mean time you started screaming bloody murder all over the place. I did not answer until now.
_____________________________________
As I see it you served multiple purposes in your actions. A BIG Thank you
You allowed me to show that I was a serious moderator, not a temperamental floozy. Thank you.
By trawling and reeling you in I showed what will happen to folks trying to troll the section. Thank you, we needed an example.
The mentors also learned something. Not to answer trolls when identified. Thank you.
Folks who were not paying attention are now. Thank you.
You have acted like a vaccine for us. Thank you.
You continuing objections and behavior led folks to revise their initial opinion of the section. Thank you.
You have lost quite a bit of your impact anywhere as you are still in the process of hurting yourself. I do not thank you for that, you just look ridiculous at the moment.
_____________________________________
Now what is next?
More tantrums?
I have no idea.
As I said in the beginning, you were trolling, I was trawling. I reeled you in. The catch of the day was good.
_____________________________________
Am I trolling you now?
No. I am stating what went on and what your impact is/was.

TheDman Loc: USA

Likely because I typed it in my post.




How you win: let everyone who wants to answer, leave it at that.




Answering questions about ppi causes grief?




"Criticizing Adobe", right? That makes sense.





"It is a setup in Adobe software that is useful in some cases, not always." Sure looks like you're trying to be a mentor. And a bad one.





Definition of troll: Anyone who asks a question that Wrongy doesn't know the answer to.

Rongnongno Loc: FL

Too bad, you had a chance to stop making a fool of yourself.

Good luck in your next endeavor.

TheDman Loc: USA

The guy making a fool of himself is the one trying to make excuses for his actions.

From my own perspective, well said, Sir. The Dman has damaged his reputation.

If stating facts damages my reputation, I'll continue to damage it until the day I die. None of you have been able to refute any of the ppi info, nor will you ever, but you'll never admit that because of this .
