如何使用指定的坐标在斐济（imagej）中进行线选择

Question

How to select a line in an image using ImageJ/Fiji by setting its start and end points? As in not drawing it over the image, but inputting the coordinates directly somewhere.

Answer 1

open script editor, select IJ1 macro and then type the code below and then run.

makeLine(1, 1, 100, 100);

This will create a line ROI between (1,1) and (100, 100).
