# Dumb question

Discussion in 'Digital Photography' started by Keith Nuttle, Oct 10, 2004.

I have been working with some maps I down loaded and was looking at
distances. It occured to me that some programs, like Irfanview, will
give you the size of a the area defined by the cursor on pixels ie used
in cropping.

Using trigometric function I can determine the diagonals in pixels of
that rectangle and then measure distance on the map.

Dumb question are pixel symmetrical? Round or square pixels; the above
works. rectangle or elipses pixels and it fails.

It depends on your monitor and PC settings.

Measure your monitor display area and calculate the ratio - its usually 3/4...
now check your scan settings... 1024 x 768 for example is also 3/4.

You can adj the scanning of your monitor and check with a ruler... when you get
it all the same ratio, it will mean square pixels.

NOW - some CRT monitors are not linear, meaning squares will only be square on
one side or on the top only, or whatever... LCD monitors are scanned cell by
cell in a matrix so they are more accurate.

I might be wrong, but I don't think this is relevant for
the original poster. I assume that he wants to meassure
distances on the map (and not on the monitor display).

Then - it depends on the map maker. It is probably OK for

If you hadn't of snipped the relevant post...

You would now see that he asked if his pixels were square or not... so he could
measure maps on his display...

Moreover -- the original poster said that he used the size
information given by IrfanView (and not an ordinary ruler).
So ... it seems like I understand the language better also

Try reading it again... here it is since you morons keep snipping the relevant
post.

Read the word 'pixels' ?? Why would he be concerned with the squareness of the
pixels? You don't have a fucking clue do you?

Pixels in Irfanview refer to the screen, not a printed map!

Comprends tu??

Now go suck your stupids friends cock and **** you!!

You are wrong and you are rude and you are stupid.
You just plonked me. But if you are to stupid to
really know how to do it, you will see this also.
And if you answer to this one we got the proof that
you cannot even plonk.

Hi Keith - the thread just went out the window
with that rude and crazy Bob.

Now - yes it will work - iff the map maker has
made a map that is symmetrical in x an y direction.
To a certain size though. When the map gets larger
you are mapping a part of a sphere to the flat map.
Then you get problems. So - I assume that it will
not work all that well for a map of the entire US
or Europe or Eurasien. But for a map of a State or
smaller it should work just fine I assume.

Sometimes you find people like this Bob one on USENET.
You just gets amazed by how dense they are - does not
seem to understand even the simplest things. And very
often they cannot write either.

Why the intense interest in sucking cock? Is it a part of your
daily routine?

If you let me know what newsreader you use, maybe I can teach
you how to plonk me, too.

why? You interested?

And what is this thread to you?

Some guy asked me if pixels were square or not because he was using the bounding
box in Irfanview to measure maps on his screen... let me quote what the trolls
keep snipping...

>I have been working with some maps I down loaded and was looking at
>distances. It occured to me that some programs, like Irfanview, will

He was using the cursor in Irfanview to draw a square box on a map on his
screen.

>Using trigometric function I can determine the diagonals in pixels of
>that rectangle and then measure distance on the map.

By using Pythagoras theorem on the number of pixels measured, he could also
measure distances in lines that intersect his boundary box coordinates.

>Dumb question are pixel symmetrical? Round or square pixels; the above

Here he wanted to know if the pixels on PC screens were square - really he was
asking if the dimensions up and down are equal - and I told him how to find out
by testing the ratio of his screen with the ratio of his display card.

So I answered his question, but he never came back.

Meanwhile, some trolls decided to tell me I was wrong for some reason - but they
snipped the post AND they didn't give the OP any answer to his question. And
this last guy decided to insult me as well - I'm just fed up with these trolls
who contribute nothing and scare off the people who try to help.

I'm not going to plonk you - I really don't care anymore. I'll just stop trying
to help people, that's all, and go back to being a lurker. I'm an electronics
technologist, and a photographer, I don't need to ask questions here for the
most part. But maybe someone's questions will go unanswered, who knows.

Peace

You raised the issue. SInce itt did not relate to the issue in
question, I thought you might have some intense interest in it.

Just one where I found someone making irrelevant and baseless
reference to someone's sexual habits on the basis of no evidence.

However, this being usenet, I don't need to gain your
permission to chime in.

Since no one but me answered the OP question... wonder why you were so
attracted?

Funny you didn't say anything about the people who made irrelevant and baseless
remarks about me... all I did was answer someone's question - and now 3
irrelevant posts against me! And I note you didn't contribute an answer
either...

It's better then war! Remember buddy - I didn't start this - the trolls did!

Anyway - color me gone, I'm deleting this useless group... and yes I know - who

I don't!
