Thank you for your kind reply!
I just calibrated the Image with these steps:
- Line Tool: 1mm = lenght = 29pixel
Distance in pixel 29
Known Distance 1
Unit of lenght mm
Now if i mark an area usino the Freehand Tool and Measure, do i get squaremm in the Area Field? And could you maybe tell me what in this case mean/min an Max stands for, because i doubt that this area is really 33square mm in reality…so i think i have
an error somewhere.
If you have an idea i would gladly hear it! Greetings from Austria,
