Graphics, Figures & Tables ⇒ Produce EPS from LaTeX File

[ghostanime2001]

How do you produce a .eps file from .tex file so that whatever is drawn in one .tex can be used in another .tex file to be included as a \includegraphics?

This is what I want to be exported as a .eps file:

Code: Select all

\documentclass{article} 
\usepackage{amsmath}
\usepackage{pgfplots}
\begin{document}

This is explained in the "Externalization Library" section of the TikZ manual. You add this to your preamble after loading the pgfplots package:

Code: Select all

\usetikzlibrary{external}
\tikzexternalize
\tikzset{external/system call={latex \tikzexternalcheckshellescape
 -halt-on-error -interaction=batchmode -jobname "\image" "\texsource";
 dvips -o "\image".eps "\image".dvi}}

If your example LaTeX source file is called file.tex, then you would get one .eps file for each tikzpicture, so in your case you'd get four: file-figure0.eps, file-figure1.eps, file-figure2.eps, file-figure3.eps. If instead you want all four tikzpictures to be exported together into a single .eps file, you'd have to modify your TikZ code to have everything in just one tikzpicture. For example, this worked for me:

Code: Select all

\documentclass{article}
\usepackage{amsmath}
\usepackage{pgfplots}
\usetikzlibrary{external}
\tikzexternalize
\tikzset{external/system call={latex \tikzexternalcheckshellescape
 -halt-on-error -interaction=batchmode -jobname "\image" "\texsource";
 dvips -o "\image".eps "\image".dvi}}

When I ran latex (not pdflatex) on that file, I got a single .eps file (file-figure0.eps) containing all four pictures.

How do I run just LaTeX ?

How do I run just LaTeX ?

Code: Select all

latex file.tex

[ghostanime2001]

I still don't understand. I am using TexWorks. Do you mean just renaming the file to .tex ?

[shadgrind]

No, just run that command in a terminal window.

If you want to do it through the TeXworks GUI, I'm not that familiar with it so I'm not the best person to ask. Maybe this guide will help. You need to setup "latex" as one of the Typeset commands.

[ghostanime2001]

What do you exactly want me to do with my .tex document. And where do I find and what do I do with a terminal window? Are u asking about cmd command window in windows 7 ?

I'd suggest you have a look at the Ghostscript utility "ps2epsi"; this will take your PostScript output (*.ps) and make an EPS out of it (the EPSI format is EPS vector graphics plus a low-resolution bitmapped "thumbnail" image, which is ignored by applications which understand EPS but used by those that don't, such as MS-Word).

If you need help with using command-line LaTeX (e.g., why a file might be called [name].tex and what it means to process this file with latex and dvips), I'd find someone locally who can help you. Using a shell (DOS, Bourne, or otherwise) is an integral part of understanding this post.

[ghostanime2001]

What if by taking the \tikzpicture environment and running pdflatex on it and making a PDF of just the diagram and crop it to include in another .tex document ? Is there a quality difference between making a encapsulated postscript of a diagram and using the plain PDF cropping way of including pictures ?
