Ruled Line

The final product being a straight line with the tick marks that can be
saved alone and or cut and pasted into a separate document.
Thank you

Dear Alex,
The following macro tool does this.
Draw the wrapping line first, and add it to the ROI manager pressing T,
then you can add tick marks using the custom tool.
All lines end in the ROI manager, so to get your 'final product', you could
create an empty copy of your image, draw all rois on it, restore the first
roi and run the straighten command.
Sincerely,

Jerome

macro "tick marks Tool - C00cT0f16T" {
if (roiManager('count')<1) exit("add at least one ROI the the roiManager");
roiManager("Show All");
getCursorLoc(x, y, z, flags);
roiManager('select',0);
run("Interpolate", "interval=1 adjust");
getSelectionCoordinates(xp, yp);
while (flags&16!=0) {
Overlay.clear;
getCursorLoc(x, y, z, flags);
d=getWidth;
for (i=0;i<xp.length;i++) {
di =  sqrt ((x-xp[i])*(x-xp[i])+(y-yp[i])*(y-yp[i]));
if (di<d) { d=di; cp = i;
}
Overlay.drawLine(x, y, xp[cp], yp[cp]);
Overlay.show;
wait(50);
}
makeLine(x, y, xp[cp], yp[cp]);
roiManager('add');
roiManager('select',0);
}

Dear Alex,
I'm sorry I deleted a curly brace while cleaning the code, so the macro in
the previous mail doesn't work. Please rather try this version, in which I
added a second tool that outputs the final line with the ticks:
https://gist.github.com/mutterer/6c19cf27938c81256f64

You can also see it in action there:
