I am very new to ImageJ and developing macros, and the extent of my experience is my familiarization with the User Guide and introduction to macros and built in macro functions. I asked this question at the end of my previous post, but the answer I received just directed me to the User Guide. I was wondering if anyone could answer this question I have and provide guidance on developing the macro that is more than just a URL to the User Guide:
How can I have a user draw an ROI (like draw a rectangle in a certain region of one of those sample images I uploaded) and then find the edges based on that ROI? I would then want to output those x coordinates of the edges into a text file.
I would appreciate any help that is specific to the functions and the thought process behind selecting the functions when creating a macro for this.
Thank you all very much!
