How do I detect if a pdf contains text that has been rotated?

[cabal-chan]

I've been looking through the docs and I can't seem to find anything on here that allows for this? This is causing issues when adding annotations to the document. How I see addressing this would be to detect if this needs to be rotated, rotate it to that amount, add annotations, and rotate it back. What's the best way to address this issue?
