[Python] How to rotate a page by arbitrary angle in pymupdf?

I couldn't find how to rotate a text page of a PDF by an arbitraty angle in the pymupdf documentation.

There is page.set_rotation(angle), however, which only allows for 0, 90, 180, 270 degrees, which is also combined in case of 90 and 270 degrees by a page orientation change.

So, I was hoping for something like:

import pymupdf

doc = pymupdf.open("Rest.pdf") # open document
page = doc[0] # get the 1st page of the document
page.set_rotation(0) # rotate the page

matrix = pymupdf.Matrix(1,0,0,1,0,0)
matrix.prerotate(2.5) # 2.5 degrees

page.add_transformation(matrix) # BUT THIS DOES NOT EXIST!

doc.save("Test_rotated.pdf")


Can this be done at all? Or do I maybe have to convert the text to an image and then rotate that image? Thank you for any hints.
