Although they are not needed for many circuit diagrams, these sizes may be required explicitly for calculations or implicitly for determining the diagram bounding ... [11]. This document describes a method for drawing electric circuits and other diagrams in L A T E X and web documents. The diagrams are drawn in the simple pic drawing language [10] augmented with m4 ... solution is to process the diagram twice. The diagram source is processed as usual by m4 and a pic processor, and the main document source is L A T E Xed to input the diagram and format the text,...
