The unit of the data in Kappa

Hi,

I would like to use the data exported by Kappa, and I have known that the measurements are based on a scale factor (in μm/pixel).

But does the curve length refer to the length in the picture? Does zooming in and out of the picture affect that length?
data
The picture I use is 500×333 pixel, does it means the curve length is 159.1544×500×333? Isn’t the value too large?

Any help would be greatly appreciated.

Thanks,
Cassie

All the measurements are set according to the scale factor you can modify in the GUI. The zoom does not affect those measurements.

If you think your curve lenght is wrong please provide an image so we can debug it.
