Render LaTeX inline code to a small image

README.md

Quick boilerplate for when you need a LaTeX inline thing converted to an image. Enter the expression in fig.tex, and run:

pdflatex fig.tex < /dev/null && convert -density 600 fig.pdf -flatten -scale 50% -quality 90 fig.jpg

Things you may want to change:

• To render block content (i.e. an equation) instead of a float or inline content, add varwidth=40em to the document options, or use \minipage for a fixed width.
• Tweak the -density, -quality and border accordingly, or produce a .png.
• Change the language.

The standalone class has a convert option but this makes babel go nuts for unknown reasons.
