How Rotate PDF works
How does the rotation actually get applied to each page?
For pages you select, the tool wraps the imported page template in TCPDF's StartTransform()/Rotate()/StopTransform() calls, rotating it around its own center and swapping the page's width and height in the new document when the angle is 90° or 270° so the canvas matches the new orientation. Pages you did not select are simply re-imported and placed unchanged.
What is a typical reason to use it?
Handy for fixing pages that were scanned sideways or upside-down in an otherwise correct document, especially when only some pages need correcting rather than the whole file.
Any quirks worth knowing about?
You can target specific pages with the same "1,3,5-8" range syntax used elsewhere in these tools, or leave it blank to rotate every page; only 90, 180, or 270 degree steps are accepted, not arbitrary angles. The code itself carries a comment flagging that its clockwise-versus-counter-clockwise sign convention was reasoned through rather than exhaustively verified, so a page rotating the "wrong" way is a known, documented edge case in the source.
