Dear all, I am using tpsDig2 to digitized my samples and I wish to scale the photos to life size using the "measure" fucntion in "Image Tools" menu. I input 10 mm as the reference length and selected two points on a ruler that are 10 mm away and then clicked "OK" to accept. The software told me that there were 66 pixels between the two points on the ruler and showed that the scale factor was 0.151359. (As the attached figure)
However, a manual calculation of 10/66 yields 0.1515152, rather than 0.151359. I am confused about why there would be such a difference, even though it is small in magnitude. Thank you in advance.
