>
> Dear ImageJ users.
>
> I would like to ask for some advice.
>
> I would like to measure line distance between two points with line tool. I
> add the points to ROI manager and would like to snap one point as a line
> begining and second point as line end. Is it possible to tell the ImageJ to
> take my point 1 (x1,y1) and point 2 (x2,y2) and draw line between them? I
> know that I can use DrawLine(x1,y2,x2,y2) but only with manual editing of
> points coordinates. Is it possible to tell the ImageJ to draw lines between
> points I have added to ROI manager in some order.
>
> Thank you for all your advices.
