Sorry i replied to the wrong email address please ignore my previous email
measurement area, i meant polygonDimension annotation. i specify a calculation and set it as content to the annotation. when i move the polygonDimension annotation, it updates its calculation whether it is resized or moved. however, the resulting calculation is different in acrobat. i based the calculation of the area with this http://www.techbluff.com/javascript/function-to-calculate-polygon-area/ or is this incorrect?
