title: How to measure distance between two point in an image and directly save in a sheet?
body: <p>I am in need to measure the distance between two point in an radiographyimage acquired (many) so i need a software that do save the distance between two point in a sheet automatically.
  I found an opensource software ImageJ that maybe can help me do this work.
  this <a href="http://imagej.nih.gov/ij/index.html" rel="nofollow">ImageJ Home page</a></p>
  
  <p>What i need also is that the line that I draw between the two point is memorized on the image.
  I see at a very first look that the program calculate the distance between one point that i draw and the zero cordinate and memorize it on a sheet.</p>
  
  <p>so i think that it can handle my need of measuring distance between two point and store in a sheet, just need to know if there is a way to do it or a plugin that can do this.</p>
  
  <p>Thanks alot</p>

  <p>P.S. Like a Two Point-by-Point measurement</p>
  
  <p>or better </p>
  
  <p>a <strong>Line by line measurement</strong> automated on every line it must memorize the lenght in result and label the line. </p>
