Drawing with TeX

There are many packages to do pictures in (La)TeX itself (rather than importing graphics created externally), ranging from simple use of LaTeX picture environment, through enhancements like eepic, to sophisticated (but slow) drawing with PicTeX. Depending on your type of drawing, and setup, here are a few systems you may consider:

- The picture environment provides rather primitive

  drawing capabilities (anything requiring more than linear
  calculations is excluded, unless a font can come to your help).  The
  environment's tedious insistence on its own ''\unitlength'', as the
  basic measurement in a diagram, may be avoided by use of the
  [[ctanpkg>picture|picture]] package, which detects whether a length is quoted
  as a number or as a length, and acts accordingly.

- epic was designed to make use of the LaTeX

  ''picture'' environment somewhat less agonising;
  [[ctanpkg>eepic|eepic]] extends it, and is capable of using ''tpic''
  ''\special'' commands to improve printing performance.  (If the
  ''\special''s aren't available, the [[ctanpkg>eepic|eepicemu]] will do the
  business, far less efficiently.

- pict2e; this was advertised in

  [[FAQ-latex-books|the LaTeX manual]], but didn't appear for nearly
  ten years after publication of the book!  It removes all the petty
  restrictions that surround the use of the ''picture''
  environment.  It therefore suffers //only// from the rather
  eccentric drawing language of the environment, and is a far more
  useful tool than the original environment has ever been.  (Note that
  [[ctanpkg>pict2e|pict2e]] supersedes David Carlisle's stop-gap

- PicTeX is a venerable, and very powerful, system, that draws

  by placing dots on the page to give the effect of a line or curve.  While
  this has the potential of great power, it is (of course) much slower
  than any of the other established packages.  What's more, there
  are problems with its [[FAQ-docpictex|documentation]].

- PSTricks gives you access to the (considerable) power of

  PostScript via a set of TeX macros, which talk to PostScript using 
  [[FAQ-specials|''\special'' commands]].  Since PostScript is itself a
  pretty powerful programming language, many astounding things can in
  principle be achieved using [[ctanpkg>PSTricks|PSTricks]] (a wide range of
  contributed packages, ranging from world mapping to lens design
  diagrams, is available).
  [[ctanpkg>Pstricks|Pstricks]]' ''\special''s are
  by default specific to ''dvips'', but there is
  a [[ctanpkg>Pstricks|Pstricks]] "driver" that allow [[ctanpkg>Pstricks|Pstricks]] to
  operate under XeTeX.  pdfTeX users may use [[ctanpkg>pst-pdf|pst-pdf]],
  which (like [[ctanpkg>epstopdf|epstopdf]] --- see 
  [[FAQ-pdftexgraphics|pdfLaTeX graphics]]) generates
  PDF files using an auxiliary program, from [[ctanpkg>PSTricks|PSTricks]]
  commands ([[ctanpkg>pst-pdf|pst-pdf]] also requires a recent installation of
  the [[ctanpkg>preview|preview]] package).
  There is a [[ctanpkg>PSTricks|PSTricks]] mailing list
  (<a href="mailto:pstricks@tug.org">pstricks@tug.org</a>) which you may
  [[https://tug.org/mailman/listinfo/pstricks|join]], or you may
  just browse the 
  [[https://tug.org/pipermail/pstricks/|list archives]].

- pgf: while pstricks is very powerful and

  convenient from "traditional" TeX, using it with pdfLaTeX is
  pretty tiresome: if you 
  simply want the graphical capabilities, [[ctanpkg>pgf|pgf]], together with
  its "user-oriented" interface [[ctanpkg>tikz|tikz]], may be a good
  bet for you.  While PDF has (in essence) the same graphical
  capabilities as PostScript, it isn't programmable; [[ctanpkg>pgf|pgf]] provides
  LaTeX commands that will utilise the graphical capabilities of
  both PostScript and PDF equally.  [[ctanpkg>Pgf|Pgf]] has extensive
  mathematical support, which allows it to rival [[ctanpkg>PSTricks|PSTricks]]'
  use of the computation engine within PostScript.
  The [[ctanpkg>pgf|pgf]] manual is enormous, but a simple introduction which
  allows the user to get a feel for the capabilities of the system, is
  available at <http://cremeronline.com/LaTeX/minimaltikz.pdf>

- MetaPost; you liked MetaFont, but never got to grips with font files?

  Try [[FAQ-MP|MetaPost]] ---
  all the power of MetaFont, but it generates PostScript figures; MetaPost
  is nowadays part of most serious (La)TeX distributions.  Knuth
  uses it for all his work...
  Note that you can 
  [[FAQ-inlgrphapp|"embed" MetaPost source in your document]] (i.e.,
  keep it in-line with your LaTeX code).

- You liked MetaFont (or MetaPost), but find the language difficult?

  ''Mfpic'' makes up MetaFont or MetaPost code for you using
  familiar-looking (La)TeX macros.  Not //quite// the full power
  of MetaFont or MetaPost, but a friendlier interface, and with MetaPost output
  the results can be used equally well in either LaTeX or pdfLaTeX.

- You liked PicTeX but don't have enough memory or time? Look

  at the late Eitan Gurari's [[ctanpkg>dratex|dratex]]: it is just as powerful,
  but is an entirely new implementation which is not as hard on
  memory, is much more readable,
  as well as in the author's book
  "TeX and LaTeX: Drawing and Literate Programming",
  which remains available from on-line booksellers.

In addition, there are several means of generating code for your graphics application (asymptote, gnuplot and MetaPost, at least) in-line in your document, and then have them processed in a command spawned from your (La)TeX run. For details, see question.
