Input: I have a LaTeX file, with plain text & math formulas.

Desired output: I want a list of elements, where each element is:

x-coordinate y-coordinate font_name character_id

Basically, I want to take a LaTeX file, r"render it", but instead of printing it / getting an image, I want it to say "okay, you have a Sigma symbol here, then you have a 'x' symbol there, ...)

What's the easiest way to achieve this? (I'm on Linux)

Thanks!
