converts latex to .png

latex2png.sh

#!/bin/bash
# converts latex to .png. It doesn't do this directly, there are temporary files saved in $dir
# To make a LaTeX-Document suitable for this, you should include

# \pagestyle{empty}

# or there will be loads of whitespace around the thing you actually want.
# Usage:
# latex2png file [density]
# file: latex file
# density: the resolution of the resulting image depends on this. 100 is rather small, 200 rather big, in my opinion. Defaults to 150.
