TeXdraw Package

The TeXdraw package consists of a set of macro definitions for the TeX typesetting program. These macros allow the user to produce PostScript drawings from within TeX and LaTeX. The main benefits of TeXdraw accrue from the ability to produce drawings from within TeX, using TeX fonts for labelling the drawing. Basic drawing features include:

• moves, lines and arrow vectors, with selectable gray level, line width, pattern, arrowhead size and type
• circles, ellipses, arcs, and Bezier curves
• general fill command to fill a region defined by lines and Bezier curves (selectable gray level)
• TeX text, including mathematics, can be positioned and superimposed on the drawing

TeXdraw has been designed to be extensible. Drawing "segments" are relocatable, self-contained units. Using a combination of the begingroup / endgroup mechanism in TeX and the gsave / grestore mechanism in PostScript, drawing segments allow for local changes to the scaling and line parameters. Using TeX's macro definition capability, new drawing commands can be constructed from drawing segments. The extensibility features include,

• relocatable drawing segments to keep changes local
• local segment scaling
• saving and restoring positions using symbolic positions
