I would like to draw a curved line in ImageJ, and then duplicate the line and move it downward for certain pixels. My final goal is to make a selection of the area in between the two curved lines.
Right now I can use the freehand lines tool to draw the curved line, and if I press T and then move it manually for certain pixels and press T again, I will have two lines with certain pixels in between. However, it is a bit time-consuming and can be hard to adjust the pixels manually. Is there a way that I can type in the pixel number to move the line? Also, how can I connect the two line to make a selection for the area in between them?
I would really appreciate if someone can offer some solutions / thoughts. Thanks
