I am using the annotation button to annotate an image. I did several annotations, however the "Length" and "Area" (in the annotation window, in the "layer regions" ) of all the annotations equal to zero. Why is that?
The annotation length and area being displayed as 0 could be a software glitch or a user error. Try restarting the program, ensuring the annotations are done correctly, or reaching out to the program's support team for further assistance.
