measurements in pixel?

Antje-2
Hi all,

I just installed the WCIF ImageJ (Version 1.38w).
I have a gray scale image, used a threshold and created a ROI from it.
Then I wanted to measure the area and got a value like 15.16 which is
definitely not in pixels... I have seen, that in the image properties
are information on how many pixels are 1 inch. So probably, it's
measured in inch???
How can I turn it off? I just want to measure in pixels and nothing else...

Could anybody help me?

Antje

Antje,

go to the menu ANALYZE

select the option SET SCALE

and write the following values in the window that pops-up:

Distance in Pixels:    1
Known Distance:     1
Pixel Aspect Ratio:  1
Unit of Length:         pixel

This will reset the scaling and give you the values of your measurements in
pixels. Cheers,

Pedro
