Hi,

Sorry, I can't comment anything, because I don't know what you mean with "measurement area annotation" (is this in the PDF specification?), and I don't understand what you mean with "when the pdf is created and i move the annotation the value is not the same". So it was right initially? And how did you move it?

To verify, maybe start with a simple shape, e.g. a right triangle or a rectangle so you can verify who is correct.

hi all

need input

so i create a measurement area annotation and this is the formula i
followed

http://www.techbluff.com/javascript/function-to-calculate-polygon-area/

however, when the pdf is created and i move the annotation the value is not
the same.

my formula for converting pixel to inches is correct since my measurement
distance annotation computation shows correct value(distance from 1 point
to the end).

i just dont understand why the area calculation is incorrect. am i missing
something else?

please advise
