LTXimg – LaTeX environments to image and standalone files

Release v2.2 [2024-04-15]

Description

ltximg is a perl script that automates the process of extracting and converting environments provided by TikZ, PStricks and other packages from input file to image formats and standalone files using ghostscript and poppler-utils. Generates a file with only extracted environments and another with all extracted environments converted to \includegraphics.

Syntax

$ ltximg [<options>] [--] <input file>.<tex|ltx>

Relative or absolute paths for directories and files is not supported. Options that accept a value require either a blank space or = between the option and the value. Multiple short options can be bundling and if the last option takes a comma separated list you need -- at the end.

Usage

$ ltximg --latex  [<options>] <file.tex>
$ ltximg --arara  [<options>] <file.tex>
$ ltximg [<options>] <file.tex>
$ ltximg <file.tex>

If used without [<options>] the extracted environments are converted to pdf image format and saved in the ./images directory using pdflatex and preview package to process <input file>.

Default environments extract

 preview  pspicture  tikzpicture  pgfpicture  psgraph  postscript  PSTexample

Example

$ ltximg --latex -e -p --subenv --imgdir mypics -o test-out test-in.ltx

Create a ./mypics directory (if it doesn’t exist) with all extracted environments converted to images (.pdf, .eps, .png) and standalone files (.ltx), a file test-in-fig-all.ltx with all extracted environments and the file test-out.ltx with all environments converted to \includegraphics using latex>dvips>ps2pdf and preview package for <input file> and pdflatex for <output file>.
