Unable to find documentation for how to rotate a cell, text, etc.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Starting with tuto1.py and modified it a below.

from pyfpdf import FPDF

pdf=FPDF()
pdf.add_page()
pdf.set_font('Arial','B',16)
g=pdf.cell(40,10,'Hello World!')
pdf.rotate(g,45)

2. I have tried to use pdf.rotate(...) to rotate the cell to an arbitray angle.
3. This may just be a documentation issue.

What is the expected output? What do you see instead?
I hope to see the text rotate by the input angle.  What I get instead is and 
error as shown below.

Thanks

For documentation, if python one isn't available, you could see php one, it 
should be similar.
