Length measurement

 

 

1. If you click on 'Length measurement' menu       * Menu > Analysis > Length measurement

    you are allowed to move selection line to a reference ruler (bottom arrow).

    Because length of line (454 pixels) is equal to 20 cm, you can set 20 cm (upper arrow)

 

 

2. Click on 'Lock current conversion factor' to maintain the same conversion factor (right arrow).

    Please move the selection line to other place (left arrow).

    As shown in the image, current length is 8.733 cm.
