RULER(9.1) RULER(9.1) NAME ruler - measure things on the screen SYNOPSIS ruler DESCRIPTION Ruler measures things on a mux(9.1) screen. Press button 1 to sweep out a rectangle anywhere on the screen. For each rectangle swept, ruler displays the coordinates of the rectangle's corners (labeled down and up), the size of the rectangle and length of its diagonal. There is a menu on button 3. The pixels and chars items control whether the size and diagonal are measured in units of pixels or characters; stop deactivates ruler without exiting; measure reactivates ruler. BUGS Character units are arbitrarily defined as the width and height of a `0' in the ruler layer. This may have nothing to do with character sizes in other layers. Ruler's menu must pop up in its own layer, perhaps far away from the cursor.
