Hi,

Is it possible to get measurement value from one page with JavaScript? If Yes, I want to add all the values up.

Thanks for help.

Do you mean the value of a "Measurement" comment? If so, then yes, it's possible.
It's simply a Line annotation and the result of the measurement is its "contents" property.

So if you select it with the mouse and run this code:

selectedAnnots[0].contents

It will print out something like this:

Distance:

6.56 cm

Since it's two lines you can access just the second one like this:

selectedAnnots[0].contents.split("\r")[1]

Yes, I measure from a pdf drawing. I want to add all the distance values up.

Then you can write a script that iterates over all the comments (annotations) in the file, checking if they're of the Line type (and maybe also if their subject is "Distance Measurement") and then parse their contents in the way I described above and add them up.
