Dear Peter,

The macro code below draws a line between two points in the ROI-manager.

roiManager("Select", 0);
getSelectionCoordinates(x, y);
x1 = x[0];
y1 = y[0];
roiManager("Select", 1);
getSelectionCoordinates(x, y);
x2 = x[0];
y2 = y[0];
makeLine(x1, y1, x2, y2);

Best wishes

Kees

Subject: snap points in roi and draw line

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.

With best regards Peter.
