Hello all,

I’m very new to Image J! I would like to know if it is possible to measure an image with the line tool and afterward get the line to stay in its place so that I can know where it was measured.

Thank you all in advance.

dear @brunomramoa,
yes ImageJ/Fiji is thought to measure and analyse and visualize images;)

I think you can start from here:
https://imagej.net/ij/docs/guide/146-30.html
and in particulare for what you are asking, you can refer to the ROI Manager:
https://imagej.net/ij/docs/guide/146-30.html#fig:The-ROI-Manager

Essentially you can draw a line with line tool then add to the ROI Manager (Analyse->Tools->ROI Manager then with Add you can add your line) and you can also save it (under the More menu of the ROI Manager.


To save the Image with line overlaid you can use the Flatten command (just look that now your new flattened image is an RGB and you can save it in your fav format).

Hoping to be helpful,
have a nice day
