# Dumb question

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 ****ing 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.
