How can I undo rotation or modify it?

[ChrisDelClea]

I want the the tool to draw from the top left corner instead of bottom left croner. How can I modify the roation? Something like a.set_rotation(180) might do?

Also examples for how to draw lines, polgyons etc. like with the square (code) would be helpful :)

pdf-annotate just uses pdfrw, if you check their docs, you should be able to use the pdf object from pdfrw to rotate the page.
