I need to duplicate this image in many other slides. I want to avoid repeating the whole code again and again. Is there any way to force latex to compile the picture once and use it in many places?
Code: Select all
\usepackage{tikz}
\usepackage{tikz-timing}
\usepackage{tikz-qtree}
\usetikzlibrary{arrows,shapes,positioning,shadows,trees,scopes,snakes}
