The latex2png scripts are tools for parsing LaTeX snippets into png images. It comes in several flavors: a shell-script, a perl-script and an Octave/Matlab-script and a python script.
I built this in 2008 while playing with mimetex.
All scripts require
- A LaTeX distribution e.g. LaTeX, MikTeX or TeTeX
- dvipng
- convert
All three scripts require a LaTeX distribution and dvipng. The shell-script will only work in a Linux distribution, e.g. Ubuntu. I have only tested this script in Ubuntu 14.01 and Travis CI.
To install a LaTeX distribution in Ubuntu type in a terminal
sudo apt-get install texlive-full
To install dvipng in Ubuntu type in a terminal
sudo apt-get install dvipng
Comment: In most Linux distributions, you will find a LaTeX binary/link in /usr/bin/latex as well as another for dvipng in /usr/bin/dvipng.
For latex2png.m, the Matlab-version of the script, you need Matlab. Matlab is a propietary scientific tool for Linux, Windows and MacOSX among others. I use Matlab a lot, and I thought about writing a function that would do the same job. I think that if you use Matlab Distributing Toolbox and/or run Matlab on a server you will find this script very useful.
The script has also been tested in Octave. To install Octave in Ubuntu type in a terminal
sudo apt-get install octave
