Only 90, 180 and 270 are accepted; anything else (including 0 and 360) fails instead of being skipped silently.
Frequently asked questions
Can I rotate only some pages?
Every page gets the same angle; per-page angles are not supported.
Do repeated rotations stack?
Yes. The written value is (existing + new) modulo 360, so rotating a 180-degree document by 90 gives 270.
Why are 0 and 360 rejected?
They mean “do nothing”, which is a meaningless request here; only the three real angles are accepted so a run can never silently succeed without changing anything.
Are content streams rewritten?
No. Only the page /Rotate entry changes; text and resources stay as they are.
