Creating a measure distanced annotation does not display the correct measurement unit, nor gives the correct calculation. Any idea which part I am doing wrong? or if there is some lacking data.
I am currently creating a measure distance annotation. Using pixel, it works just fine. but since now i am taking into account actual measurement and unit, i am not sure which part of code i am having problem with or if i am lacking something.
Please see image. That is some application i use to create a distance annotation and i calibrate it that that distance is 14.5cm so by dividing it by pixel, the calibration value per pixel would be 0.0519548.
Now, when I apply it to iText code, i am confused why the display is always still in inches? Even if i set my code to be inches and not cm, the calculation is incorrect.
I am not entirely sure what the problem is.
