Hi!

I was using the code presenting in this documentation https://www.mathworks.com/help/images/measure-distances-in-images.html and I get an error in the first line of the startDrawing function. The error is: Undefined variable "images" or class "images.roi.Line".

Why this is happening?

Thanks!

It will be solved if you install the 'image processing toolbox' :)

It needed at least R2018b.

images.roi.Line needs at least R2018b I believe.

Do you know other way of doing this measurement?
