I am measuring bacteria ratios for various species and I need to be able to make several measurement at the center and quarter marks of the diameter. I did a macro to get the quarter points along the diameter to make the three other horizontal measurements when I hit draw. This works perfectly on my larger bacteria with very clear images, but this width is too large when I get to my smallest bacteria. I have found that the line segment tool is the perfect size for all my measurements and line widths, but I believe it is in screen pixels rather then image pixels. I have drawn a picture that shows what I need, but I need it done at the thickness of the line segment tool (on the right) for smaller bacteria.
