# Upload Tex

`POST /image/upload-tex`

Accepts a base64-encoded LaTeX source, compiles it in a sandboxed temp
dir, rasterises the PDF and returns one image URL per page.

Used by the exercise import to recover the figures a .tex draws (TikZ,
tables of variations, probability trees): the source is imported as
text either way, the page images only exist so the printed figures can
be cropped out of them. A source that does not compile answers
compiled=False with 200 — the import carries on without figures.
