tex­draw – Graph­i­cal macros, us­ing em­bed­ded PostScript

TeXdraw is a set of macro def­i­ni­tions for TeX, which al­low the user to pro­duce PostScript draw­ings from within TeX and LaTeX. TeXdraw has been de­signed to be ex­ten­si­ble. Draw­ing ‘seg­ments’ are re­lo­cat­able, self-con­tained units. Us­ing a com­bi­na­tion of the TeX’s group­ing mech­a­nism 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.
